Congratulations to ICB&DD Member, Dr. Tadashi Honda for his research breakthrough on NASH (non-alcoholic steatohepatitis) published recently in the Journal of Cellular and Molecular Gastroenterology and Hepatology (CMGH).
(Press release from University of Dundee)
ICB&DD Member and Research Professor of the Department of Chemistry, Dr. Tadashi Honda along with a team of scientists from University of Dundee and Saint Andrews University in the United Kingdom, recently published their research breakthrough on NASH (non-alcoholic steatohepatitis). NASH, a form of liver disease which threatens to become a modern epidemic due to its association with obesity and type 2 diabetes. Both major health issues for modern society may be stopped in its tracks thanks to this research breakthrough. They found that the liver disease known as NASH (non-alcoholic steatohepatitis) could not only be stopped but that the damage it causes, including cirrhosis of the liver, could be reversed. Lifestyle choices within industrialised societies that entail over-consumption of energy-dense food and physical inactivity have led to an explosion in the incidence of obesity and type-2 diabetes. Approximately 10-15 per cent of obese individuals with type-2 diabetes will develop the form of liver disease called NASH, which is characterised by the coexistence of fat deposits and inflammation within the liver. “This condition is particularly sinister because it is difficult to identify affected patients, and even when a correct diagnosis is made there are currently no satisfactory treatments for the disease,” said Professor John Hayes, Chair of Molecular Carcinogenesis in the School of Medicine at the University of Dundee. “Most alarmingly, NASH will progress into more serious irreversible forms of liver disease in a substantial number of patients that can only be remedied by liver transplantation. In particular, NASH can progress to liver cirrhosis, and this in turn can ultimately give rise to liver cancer. Given the large portion of the population that are obese (30% of adults), many health professionals regard type-2 diabetes and NASH as a modern epidemic which in the long term will create enormous societal and economic distress. Clearly, we urgently need treatments that can inhibit NASH and prevent it from developing into cirrhosis and cancer.”
Professor Hayes and colleagues including Professor David Harrison at the University of St Andrews and Professor Tadashi Honda at Stony Brook University in the USA have now reported a breakthrough which could lead to just such treatments. They focused on the fact that NASH is associated with the accumulation within the liver of a group of highly damaging and oxidizing molecules called reactive oxygen species (ROS). They believed that the `master controller’ of cellular antioxidant systems, called Nrf2, might prevent NASH resulting from obesity, based on a hypothesis that antioxidants neutralise ROS. Professor Hayes explained, “We used an existing pre-clinical drug called TBE-31, that was invented and made by Professor Honda to activate Nrf2 in mice, anticipating that natural antioxidant defence systems within liver cells would be switched on and that this should supress ROS levels and prevent liver damage. “We found that treatment with TBE-31 not only decreased the severity of diabetes and improved insulin sensitivity but it also exerted a range of beneficial effects within the liver.”
The drug greatly diminished fat synthesis and fat accumulation, inflammation and oxidative damage within the liver. The researchers also found, to their surprise, that TBE-31 also markedly decreased scarring in the liver. “These results are particularly exciting because they show for the first time that a drug that activates Nrf2 and switches on antioxidant defence genes can reverse both NASH and cirrhosis,” said Professor Hayes. “The fact that Nrf2 activation targets both liver disease and diabetes is quite remarkable. Moreover, the fact Nrf2 activation confers multiple benefits makes the strategy clinically attractive and potentially very robust. "This study demonstrates that established NASH and fibrosis can be reversed using drugs that activate Nrf2 and provides the proof of concept for moving this research into patients. Importantly, there are already drugs that are known to be safe in humans that can activate Nrf2. We should now move forward into clinical trials of Nrf2 activators in patients with NASH.”
The results of the research are published in the journal Cellular and Molecular Gastroenterology and Hepatology (CMGH). The research has been funded by the Medical Research Council, Stony Brook Foundation and Reata Pharmaceuticals, Inc.

ICB&DD Eleventh Annual Symposium
On Friday, October 6, 2017, the ICB&DD hosted its Eleventh Annual Symposium entitled, “Frontiers in Chemical Biology and Drug Discovery” at the Charles B. Wang Center, Stony Brook University. This year it was also held as the second joint-symposium with Icahn School of Medicine at Mount Sinai. The Symposium featured eight Plenary Lecturers: Dr. Michael Airola, Assistant Professor, Department of Biochemistry and Cell Biology, Dr. Jingfang Ju, Department of Pathology, Stony Brook School of Medicine, Dr. Dima Kozakov, Assistant Professor, Department of Applied Mathematics and Statistics and Dr. Nicole Sampson, Professor, Department of Chemistry. These four speakers represented Stony Brook University. Dr. Ming-Ming Zhou, Professor and Chairman, Department of Pharmacological Sciences, Dr. Dusan Bogunovic, Assistant Professor, Department of Microbiology, Dr. Arvin Dar, Assistant Professor, Department of Oncological Sciences and Dr. Michael Lazarus, Assistant Professor, Department of Pharmacological Sciences. They represented Icahn School of Medicine at Mt. Sinai. The event was very well attended by a diversified audience composed of faculty, research staff and students on campus, as well as universities and industries in the Greater New York metropolitan area. The Poster Session equally attracted a large participation of students from Stony Brook University, the Laufer Center for Physical and Quantitative Biology, Icahn School of Medicine at Mt. Sinai School, Chembio Diagnostics Systems Inc., among others. There were 60 scientific posters presented at the Poster Session.
Dr. John Haley, Research Associate Professor of Pathology, Stony Brook University and Chair of the Symposium Organizing Committee, opened the Symposium and introduced Dr. Scott L. Friedman, Dean of Therapeutic Discovery, Icahn School of Medicine at Mount Sinai, who gave the welcoming remarks and briefly described the background and importance of the SBU-ISMMS joint-symposiums. Then, Dr. Haley introduced Dr. Kenneth Kaushansky, Dean, Stony Brook University School of Medicine. Dr. Kaushansky congratulated the joint symposium, emphasized the importance of the collaboration between the two institutions, and then introduced Dr. Iwao Ojima, Distinguished Professor and Director of ICB&DD. Dr. Ojima concisely summarized the history of accomplishments and the current and future goals of ICB&DD.
Dr. Steven Glynn, Assistant Professor, Department of Biochemistry, introduced the First Plenary Lecturer, Dr. Ming-Ming Zhou, Dr. Harold and Golden Lamport Professor and Chairman, Department of Pharmacological Sciences, Icahn School of Medicine at Mount Sinai, who gave a lecture entitled, “From Epigenetic Structural Mechanism to Targeted Therapy”. In his presentation, Dr. Zhou provided an overview of his investigative team’s latest structural and mechanistic study of protein-protein interactions involving master transcription factors and core histones that play an important role in epigenetic control of gene transcription, cell proliferation and lineage-specific differentiation. In addition, he discussed the functional implications of the new findings on the basic principles that govern the molecular interactions and regulation in gene expression and strategies for developing new targeted epigenetic therapy for human diseases, including cancer and inflammation.
Dr. John Haley, introduced the second Plenary Lecturer, Dr. Jingfang Ju, Professor, Department of Pathology, Stony Brook University School of Medicine, who gave a lecture entitled, “The Development of miRNA-Based Therapeutics for Colorectal Cancer”. In his presentation, Dr. Ju discussed his laboratory’s findings that the translational regulation of suspected genes in cancer has come to a new frontier in recent years. He stated that, “Mounting evidence showed that post-transcriptional and translational controls mediated by various regulatory molecules, such as RNA-binding proteins and non-coding RNAs (e.g. miRNAs), are critically important.” His team “uncovered a novel mechanism that a number of miRNAs were regulated by tumor suppressor p53 in colon cancer. Such a regulatory mechanism is important in regulating cell proliferation and cell cycle control.” He believes that, given the significant role of miRNAs in many aspects of tumor development such as proliferation, autophagy, cell cycle control, invasion, EMT and maintained tumor stem cell phenotype, he is hopeful that miRNA based therapeutics, diagnosis and prognosis may emerge in the near future to benefit patients.
Dr. Maurizio Del Poeta, Professor, Department of Molecular Genetics and Microbiology introduced the third Plenary Lecturer, Dr. Dusan Bogunovic, Assistant Professor, Department of Oncological Sciences and Department of Pharmacological Sciences, Icahn School of Medicine at Mount Sinai, who gave a lecture entitled, “Broad Spectrum Antivirals: Human Genetics Leading Therapy”. In his presentation, Dr. Bugunovic discussed his group’s use of next-generation sequencing in the discovery of humans who have augmented protection against viral infections. He stated that, “These individuals have loss-of-function mutations in ISG15, a negative regulator of Type I interferon (IFN) pathway. Clinically, ISG15 deficient individuals are largely asymptomatic, but functionally have low-level, persistent transcription of IFN stimulated genes”. He reported that his research group has recently demonstrated that “this small amount of IFN stimulated gene transcripts confers increased protection against a broad spectrum of viruses”.
Dr. Martin Kaczocha, Assistant Professor, Department of Anesthesiology , introduced the fourth Plenary Lecturer, Dr. Arvin Dar, Department of Oncological Sciences and Department of Pharmacological Sciences, Icahn School of Medicine at Mount Sinai, who gave a lecture entitled, “A Whole Animal Platform to Advance a Clinical Kinase Inhibitor into New Disease Space”. In his presentation, Dr. Dar described his research and studies on signal transduction networks at multiple levels: structurally, biochemically, within cells, and also within whole animals. He stressed that a goal of his research program is “to build the tools that will allow us to modulate signaling networks within the context of cells and animals for therapeutic applications”. In his talk, Dr. Dar presented his recent work, employing methods from synthetic organic chemistry, X-ray crystallography, informatics, biochemistry and model organism genetics to develop novel kinase inhibitors.
Dr. Scott Laughlin, Assistant Professor, Department of Chemistry, introduced the fifth Plenary Lecturer, Dr. Nicole Sampson, Department of Chemistry, Stony Brook University, who gave a lecture entitled, “Cholesterol Metabolic Pathways in M. tuberculosis: Opportunities for Tuberculosis Drug Discovery and Diagnosis”. In her presentation, Dr. Sampson stated that, “Tuberculosis (TB) is the number one killer from infectious disease in the world. Current drug regiments are lengthy and toxic, and new approaches to TB treatment are needed.” She stressed that, “existing diagnostic tools fail to confirm TB in most children, who typically have disease with low bacterial counts”. Mycobacterium tuberculosis (Mtb), is the causative agent of TB, and infects and divides inside human immune cells. The ability of Mtb to metabolize human cholesterol is critical for the maintenance of the Mtb infection in these cells. She stressed that, building on her laboratory’s biochemical basis on the cholesterol metabolism, her team has identified potential avenues for both diagnosing TB disease more readily, particularly in children and improving treatment of TB.
Dr. Robert Rizzo, Professor, Department of Mathematics introduced the sixth Plenary Lecturer, Dr. Dima Kozakov, Assistant Professor, Department of Applied Mathematics and Statistics, Faculty Member, Laufer Center for Physical Quantitative Biology, Stony Brook University, who gave a lecture entitled, “Modeling and Modulation of Protein Interactions”. In his presentation, Dr. Kozakov focused on the understanding of the key principles of disrupting protein-protein interactions using small molecules, macrocycles or other compounds because modulating protein interactions for therapeutic purposes has become one of the modern frontiers of biomedical research. His group accomplished the disruption of the protein-protein interactions by introducing the concept of hot spots, which are regions of surface that disproportionally contribute to binding free energy. Hot spots were determined by modeling the interaction of proteins with a number of small molecules used as probes. This method is a direct computational analogue of experimental techniques, and uses the FFT-based sampling approach. Dr. Kozakov then demonstrated how these hot spots provided information on the ability of drug-like small molecules for binding to the site of protein-protein interactions, as well as allosteric sites.
Dr. Jarrod French, Department of Biochemistry, introduced the seventh Plenary Lecturer, Dr. Michael Airola, Assistant Professor, Department of Biochemistry and Cell Biology, Stony Brook University, who gave a lecture entitled, "Structure, Function, and Inhibition of Lipid Metabolism in Cancer". In his presentation, Dr. Airola explored his observation, “During the past thirty years, the perceived role of lipids has shifted from simple structural components of cell membranes to bioactive molecules that regulate critical cellular and pathological processes”. He stated that, “The enzymes that generate and breakdown these bioactive lipids have emerged as novel therapeutic targets for treating the leading causes of diseases in the United States, including cancer”. In his talk, Dr. Airola presented new insight into the way that two key enzymes in sphingolipid metabolism work at the molecular and structural level. These include the colon cancer therapeutic target, human neutral ceramidase, and the membrane-associated enzyme, neutral sphingomyelinase 2 which has established roles in neurodegeneration, metastasis, and intracellular communication.
Dr. Adam Rosebrock, Assistant Professor, Department of Pahtology, introduced the eighth Plenary Lecturer, Dr. Michael Lazarus, Assistant Professor, Department of Pharmacological Sciences, Icahn School of Medicine at Mount Sinai, who gave a lecture entitled, “The Incredible ULKs: Structure and Inhibition of Autophagy Kinases”. In his presentation, Dr. Lazarus discussed his research team’s research on small molecule inhibitors against key enzymes of a family of kinases, called ULKs that initiate autophagy. He identified autophagy as a “fundamental cellular pathway conserved from yeast to humans” which is “necessary for development and normal cellular function”. “These enzymes diverged from the yeast kinase Atg1 and have more complex roles in mammalian cells in general and in cancer in particular.” His group “solved the first structure of ULK1 and is developing inhibitors to probe the therapeutic value of targeting autophagy alone or as a combination treatment for numerous malignancies”. Dr. Lazarus stressed that the strategy of targeting ULK1 and ULK2 could be beneficial for cancer treatment.
Dr. Elizabeth Boon, Associate Professor, Department of Chemistry gave the closing remarks, thanking the Plenary Lecturers for their outstanding presentations as well as the Organizing Committee members for their successful planning and execution of the Eleventh Annual ICB&DD Symposium.
The best three posters of the 60 scientific papers presented in the Poster Session were selected for the Poster Awards. Dr. Jarrod French, Chair of the Poster Session Committee presented the awards to the selected winners. The award winning posters this year were Krupa Haranahalli from the laboratory of Dr. Iwao Ojima for her poster entitled:“SAR Study on Novel Anti-Fungal Agents Targeting the Synthesis of Fungal Sphingolipids”, Pratik Kumar from the laboratory of Scott Laughlin, for his poster entitled: “3-N Spirocyclopropenes Provide Spatiotemporal Control of Bioorthogonal and Jennie B. Altman from the laboratory of Dr. Bogunovic, Department of Microbiology, Icahn School of Medicine at Mount Sinai for her poster entitled: “Broad Spectrum Antivirals - Human Genetics Leading Therapy Utilizing ISG15 Deficiency”.

Congratulations to ICB&DD Project Member, Dr. Galina Botchkina for having her licensed PPT2 Prostate Cancer Stem Cell Line recently launched as a product catalog in Millipore.
ICB&DD congratulates, Project Member, Dr. Galina Botchkina for having her licensed PPT2 Prostate Cancer Stem Cell Line recently launched as a product catalog (# SCC104) in Millipore.
PPT2 is a spontaneously immortalized prostate cancer cell line that expresses cancer stem cell markers including CD133, CD44, EpCAM and CD166. PPT2 cells possess high sphere-forming, clonogenic and tumorigenic capacities and are extremely resistant to anti-cancer drugs. The PPT2 line is negative for tumor suppressor genes p53 and p21 and do not express AR and PSA, and only a small fraction of the PPT2 cells express p63.
The PPT2 prostate adenocarcinoma cell line was established from a stage pT2c pNX pMX prostate cancer patient. Primary tumor cells were obtained by needle biopsy from the resected prostate carcinoma and established in culture on type-I collagen using serum free stem cell media. PPT2 cells were selected based upon their ability to form 3D spheroids over prolonged passages. Cells were serially transplanted in NOD/SCID mice tumor xenografts and propagated as a mixture of floating 3D spheroids and type I collagen adherent cells. PPT2 is a unique, cancer stem cell (CSC) enriched, human prostate cancer cell line useful for CSC-targeted drug development and research focused on cancer cell and CSC biology.

On Thursday, October 6, 2016, the ICB&DD hosted its Tenth Annual Symposium entitled, “Frontiers in Structural and Computational Biology” at the Charles B. Wang Center, Stony Brook University. The Symposium featured eight Plenary Lecturers. Lecturer, Dr. Ken A. Dill, represented the Laufer Center for Physical and Quantitative Biology of Stony Brook University. The event was very well attended by a diversified audience composed of faculty, research staff and students on campus, as well as universities and industries in the Greater New York metropolitan area. The Poster Session equally attracted a large participation of students from Stony Brook University, the Laufer Center for Physical and Quantitative Biology, Mt. Sinai School of Medicine, Chembio Diagnostics Systems Inc., among others. There were 65 scientific posters presented at the Poster Session. Dr. Huilin Li, Professor at the Van Andel Research Institute, former Professor of Biochemistry and Cell Biology, Stony Brook University and Chair of the Symposium Organizing Committee, opened the Symposium and introduced Dr. Richard Reeder, Vice President for Research at Stony Brook University, who gave the welcoming remarks for the Symposium. Then Dr. Lee introduced Dr. Iwao Ojima, Distinguished Professor and Director of ICB&DD. Dr. Ojima concisely summarized the history of accomplishments and the current and future goals of ICB&DD.
Dr. Robert Rizzo, Professor, Department of Applied Mathematics and Statistics, introduced the first Plenary Lecturer, Dr. Wendy Cornell, Principal Research Staff Member, Soft Matter Science, IBM T. J. Watson Research Center, who gave a lecture entitled, “Data Mining and Integration for Drug Discovery Pipeline Decision Support”. In her presentation, Dr. Cornell provided an overview of her research which focuses on the drug discovery process involving numerous stage gates where targets, compounds, clinical trials, and other key options are prioritized and Go/NoGo decisions are made. She described the generation and application of a variety of different decision support models and workflows based on protein structural, protein sequence, and pharmacological data as well as structured and unstructured textual sources and the resulting impact.
Dr. Peter Tonge, Professor, Department of Chemistry, introduced the second Plenary Lecturer, Dr. Da-Neng Wang, Professor, Skirball Institute of Biomolecular Medicine, NYU Medical School, who gave a lecture entitled, “Structure and Mechanism of a Bacterial Sodium-Dependent Dicarboxylate Transporter- Implications in Fatty Acid Synthesis and Obesity”. In his presentation, Dr. Wang discussed the factors, such as its direct import across the plasma membrane via the Na+- dependent citrate transporter (NaCT) which influence the concentration of cytosolic citrate, a major precursor for the synthesis of fatty acids, triacylglycerols, cholesterol and low density lipoprotein in liver and adipose cells. He stated that mutations of the homologous transporter gene in flies (INDY) result in reduced fat storage through calorie restriction. His research team has determined the 3.2 Å crystal structure an INDY homolog from Vibrio cholera. In conclusion, he indicated that homology modeling of the human NaCT protein has been used to understand its interaction with various small molecules.
Dr. David Green, Associate Professor, Department of Applied Mathematics and Statistics, introduced the third Plenary Lecturer, Dr. Ken A. Dill, Distinguished Professor and Director of the Laufer Center for Physical and Quantitative Biology, Member of the National Academy of Sciences, who gave a lecture entitled, “Melding Physical Simulations with Fuzzy Information for Computational Folding and Binding”. In his presentation, Dr. Dill discussed the computing of the folded or docked structures of proteins using physics-based molecular simulations. He stated that physical simulations have the advantage of capturing energies in addition to structural information, satisfying the Boltzmann distribution law, and giving dynamic and mechanistic information. He described the MELD method where he and his research team would speed up physical simulations by using fuzzy and uncertain external information and how MELD could help in experimental structure determination and finding native states of small proteins. He concluded by stating that he was optimistic that the MELD accelerator would add value to molecular dynamics modeling.
Dr. Markus Seeliger, Associate Professor, Department of Pharmacological Sciences, introduced the fourth Plenary Lecturer, Dr. James Wells, Chair, Department of Pharmaceutical Chemistry, University of California, San Francisco, who gave a lecture entitled, “Challenging Targets for Drug Discovery: ‘The High Hanging Fruit’”. In his presentation, Dr. Wells described Tethering, a fragment-based discovery approach used to probe the surfaces of proteins that engage in protein-protein interactions or that may be regulated by allosteric interactions. He stated that for these sites, plasticity and conformational adaptability of proteins has begun to reveal new opportunities for drug discovery on targets previously assumed to be undruggable. Although protein-protein interfaces are generally flat and large, small fragment molecules can be found that bind with much greater ligand efficiency to “hot-spots” and in crevices that protein partners do not exploit. In addition, the site-directed nature of Tethering makes it very useful for exploring allosteric sites that may not be found by typical screening approaches. These technologies and the intrinsic adaptability and flexibility of proteins dramatically expand the opportunities for drug discovery at protein-protein interfaces and allosteric sites.
Dr. Huilin Li, Professor at the Van Andel Research Institute and former Professor of Department of Biochemistry and Cell Biology at Stony Brook University, introduced the fifth Plenary Lecturer, Dr. Grant Jensen, Principal Investigator, HHMI and California Institute of Technology, Department of Biology, Broad Center for the Biological Sciences, who gave a presentation entitled, “Structural Biology in vivo Through Electron Cryotomography”. In his presentation, Dr. Jensen stated that in the last ten years, electron cryotomography has made it possible to visualize large macromolecular assemblies inside intact cells in a near-native, "frozen-hydrated" state in 3-D to a few nanometers resolution and that atomic models of individual proteins and smaller complexes obtained by X-ray crystallography, NMR spectroscopy, or other methods can be fit into cryotomograms to reveal how the various pieces work together inside cells. He stressed that a few good pictures are sometimes all that is needed to distinguish between competing models. Dr. Jensen then summarized the key technological advances that have made electron cryotomography possible and then presented several examples of current results from his research group’s recent work in bacterial cell biology, including new images and mechanistic insights into bacterial chemoreceptor arrays, secretion systems, and the Type IV pilus to illustrate these points.
Dr. Liang Gao, Assistant Professor, Department of Chemistry, introduced the sixth Plenary Lecturer, Dr. Clint Potter, Co-Director, Electron Microscopy, New York Structural Biology Center, who gave a lecture entitled, “New Challenges for Molecular Electron Microscopy”. In his presentation, Dr. Potter focused on the dramatic improvements in the progress of Molecular Electron Microscopy (EM), and a set of techniques and approaches used to analyze the structure of macromolecular machines using a transmission electron microscope (TEM). He stated that new detectors and image processing software have enabled the reconstruction of atomic resolution maps for large well-ordered macromolecules and that high levels of automation in image acquisition and processing have enabled the reconstruction of multiple different states of molecular machines from a single sample. Dr. Potter then provided an overview of the new technology being used to understand structures that may be highly heterogeneous and/or dynamic and illustrated how the power of this method can be applied in the understanding of molecular machines.
Dr. Miguel Garcia-Diaz, Associate Professor, Department of Pharmacological Sciences, introduced the seventh Plenary Lecturer, Dr. Leemor Joshua-Tor, Professor and Dean of Watson School of Biological Sciences, HHMI Investigator, Cold Spring Harbor Laboratory and HHMI, who gave a presentation entitled, “Mad About U: Regulating the Let7 Pre-miRNA”. In her presentation, Dr. Tor explored the key mechanistic features of the steps in the regulation of the let-7 family of regulatory miRNA. She stated that Lin28 is the pluripotency factor that inhibits the biogenesis of the let-7 family. Lin28 is highly expressed in embryonic stem cells and has a fundamental role in development and tissue regeneration. It is an oncogene in a subset of human cancers, while let-7 is a tumor suppressor, that silences several human oncogenes. She described the process by which Lin28 triggers the suppression of mature let-7 expression in stem cells and certain cancer cells.
Dr. Carlos Simmerling, Professor, Department of Chemistry, introduced the eighth Plenary Lecturer, Dr. Charles L. Brooks III, Warner-Lambert/Parke-Davis Professor of Chemistry and Biophysics, Department of Chemistry and Biophysics, University of Michigan, who gave a presentation entitled, “High-Throughput, Free Energy Based Ligand Discovery and Optimization Using Multi-Site λ-Dynamics”. In his presentation, Dr. Brooks discussed his research group’s development of an extended Lagrangian approach to free energy simulations called λ-dynamics and a multi-site version, which he termed multi-site λ-dynamics. He stressed that this system of interest “’evolves’ dynamically in the space of chemical substituents of interest and thus significantly enhances the efficiency of the search problem and convergence of the overall free energy calculations”. Dr. Books then described the extended Lagrangian methodology and illustrated it in the context of large- scale ligand screening calculations and then concluded his presentation by discussing generalizations to permit both sequence-based resistant mutations and ligand affinities.
Dr. Robert Rizzo gave the closing remarks, thanking the Plenary Lecturers for their outstanding presentations as well as the Organizing Committee members for their successful planning and execution of the Tenth Annual ICB&DD Symposium.
The best three of the 65 posters presented in the Poster Session were selected for the Poster Awards. The award winning posters this year were presented by Amber Bonds from the research group of Dr. Nicole Sampson for her poster entitled, “Elucidating the Mechanisms of Cholesterol Metabolism in Mycobacterium Tuberculosis”; T. Dwight McGee Jr. from the research group of Dr. Robert Rizzo for his poster entitled, “Exploiting Targetable Events in HIV Entry with Small-Molecule Inhibitors” and Xin Wang from the research group of Dr. Iwao Ojima for her poster entitled, “SB-T-1214 and Biotin Functionalized Gold Nanoparticles”.
The 10th ICB&DD Symposium culminated with a wonderful dinner at the Chapel of the Charles B. Wang Center. Among the attendees were Kenneth Shroyer, Chair of the Department of Pathology and Maria Ryan, Chair of the Department of Oral Biology and Pathology.

Congratulations to Drs. Francis Johnson and Maria Ryan, Co-Investigators of a newly funded grant from the National Institute of Dental and Craniofacial Research (NIDCR) to advance treatment of Periodontal Disease.
In a pioneering partnership that could lead to new treatments for periodontal disease, Stony Brook University’s School of Dental Medicine and Traverse Biosciences have received a $1.3 million award from the National Institute of Dental and Craniofacial Research (NIDCR) of the National Institutes of Health (NIH). The funding is intended to further evaluate the pre-clinical safety and effectiveness of the Traverse’s leading drug candidate, TRB-N0224, for the treatment of periodontal disease. The research will be led by Lorne Golub, DMD, in the Department of Oral Biology and Pathology, and Ying Gu, PhD, DDS, in the Department of General Dentistry at the School of Dental Medicine. They will serve as co-principle investigators of the award, in close collaboration with Traverse Biosciences.
Periodontal disease is one of the most prevalent diseases in the world, includes the major conditions of gingivitis and periodontitis, and is the primary cause of tooth loss in adults. The Centers for Disease Control (CDC) estimates that the prevalence of periodontitis in U.S. adults aged 30 years and older is 47.2% (64.7 million people). Periodontal disease has also been associated with other chronic conditions such as heart disease, diabetes, and various cancers. Periodontal disease also impacts companion animals, including dogs, cats and horses. Canine periodontal disease affects approximately 80% of dogs by the age of three, with the highest incidence in smaller breeds and older animals.
In 2015, Traverse Biosciences signed an exclusive, worldwide license agreement with the Research Foundation for the State University of New York to develop a drug to treat canine periodontal disease. The leading drug candidate that has emerged and will be evaluated under the this NIDCR grant is derived from laboratory discoveries by Dr. Golub and Dr. Francis Johnson, President of Chem-Master International Inc., and Professor of Chemistry and Pharmacological Sciences at Stony brook University. They developed a library of drug candidates that are chemically-modified curcumins, which are designed to treat inflammation. The patents for the novel compounds list Drs. Golub and Johnson as the inventors. Traverse Biosciences will evaluate TRB-N0224 for the treatment of periodontal disease in both humans and animals.
“I am very pleased that Traverse Biosciences has been able to attract the financial resources necessary to advance this highly collaborative research and development program,” said Dr. Golub, SUNY Distinguished Professor and also a Scientific Co-Founder of Traverse Biosciences. “With this critical support from NIDCR, we can accelerate the commercialization of this platform technology for the treatment of periodontal disease, as well as a variety of other chronic inflammatory conditions.”
Joseph Scaduto, MS, MBA, Founder and CEO of Traverse Biosciences, stated, “We are working to successfully commercialize TRB-N0224 as an FDA-approved pharmaceutical intervention for the treatment of chronic inflammatory diseases in both humans and companion animals, including periodontal disease.” He added, “This award from the National Institute of Dental and Craniofacial Research provides an infusion of non-dilutive capital that will allow us to demonstrate the pre-clinical safety and efficacy of this lead drug candidate.”
Dr. Gu, Associate Professor of Dentistry, commented, “I look forward to evaluating the therapeutic efficacy of TRB-N0224 to treat periodontal disease, and I am very pleased to work with Traverse Biosciences on this project. I strongly believe there is a need to develop new and improved therapeutics to manage chronic inflammatory diseases such as periodontitis. With this grant, we, as a team with Dr. Hsi-Ming Lee, a Research Assistant Professor in Oral Biology and Pathology, will be able to advance our research from bench top to chair side, from idea to commercialization.” She added, “It is exciting to work closely with a new venture to develop a promising biomedical technology invented here at Stony Brook University”
Dr. Maria Ryan, a Co-Investigator on the award and Chair of the Department of Oral Biology and Pathology said, “The Department of Oral Biology and Pathology has been a prolific source of innovation throughout its history with numerous products successfully developed and commercialized. I am so proud to see this legacy continue with the invention of TRB-N0224 and our fruitful partnership with Traverse Biosciences.”
The NIDCR award is defined as a Phase II Small Business Technology Transfer (STTR) grant. Some of the STTR funding goes directly to the laboratory of Drs. Golub and Gu, and the work they and colleagues are doing evaluating the compounds in the School of Dental Medicine. The other portion of the funding goes to Traverse Bioscience for drug development and commercialization.

Antifungal Work Lands Dr. Maurizio Del Poeta $6 million from NIH
Like the fictional Steve Austin, Stony Brook University’s Maurizio Del Poeta has become the ““Six Million Dollar Man.”
No, Del Poeta didn’t crash in an experimental spacecraft; and no, he doesn’t have bionic limbs. Instead, work with a potentially deadly fungus in his laboratory helped Del Poeta, a professor in the Department of Molecular Genetics & Microbiology at Stony Brook University, earn two, multiyear $3 million grants from the National Institutes of Health. Del Poeta is attacking a fungus that can be deadly, particularly for people with weakened immune systems. Recently, his approach yielded an unexpected result that may lead to a vaccine. “We were looking for a gene that would metabolize a fungal sphingolipid on the surface of the fungus,” he said. The gene he mutated caused a different function than expected, leading mice with exposure to this strain to become resistant to fungal infection, Del Poeta said. This change may be the key to providing a vaccination against Cryptococcus neoformans, a fungus present in numerous places, including in bird droppings. “We think that this discovery will open the road to a new vaccination strategy against fungi” including candidiasis caused by Candida albicans or aspergillosis, caused byAspergillus funigatus, Del Poeta said. The same gene for sterol glucosidase that Del Poeta and the researchers in his lab mutated is also found in the genome of these other fungal species. “One could potentially make a vaccine containing the three fungal mutants combined and inject them together to protect simultaneously” against all three species, he said. These three infections account for over 1.3 million deaths per year, according to the Centers for Disease Control and Prevention. This vaccine could prove effective for immunocompetent and immunocompromised individuals. A potential vaccine is particularly important for the latter group.
Del Poeta and his colleagues injected the mutated version of the fungus into an animal model that mirrored the conditions of a patient with the human immunodeficiency virus. The vaccine “protected 100 percent” against an infection, Del Poeta said. “Whatever this mutant is doing, the protection is not determined by the presence of CD4 cells.” CD4 cells are a type of white blood cell that fights infection. They are at the center of vaccines that train the immune system to recognize and destroy live versions of infections. Without those cells, vaccination becomes more difficult, but, clearly, not impossible. His results earned him a 1 score, the top mark from reviewers, from the National Institutes of Health, which recently awarded him a $3 million grant to study this mutated fungus. The grant should become active on July 1. John Perfect, the James B. Duke Professor of Medicine and chief of the Division of Infections Disease at Duke University, brought Del Poeta into his laboratory from Italy. He is proud of his protege, describing Del Poeta in an email as a “major investigator in fungal pathogenesis.” An important question Del Poeta can’t answer is how this attenuated strain conveys resistance. Before this promising early work can become a part of preventive treatment, Del Poeta said he and his team will look for a different formulation of this potential vaccine.
“It will be difficult to convince the FDA to administer a live fungus to an immunocompromised patient, even if the fungus will be attenuated,” he explained. “So, we need to make a better vaccine.” His postdoctoral researcher, Antonella Rella, who is the first author on a paper published in Frontiers in Microbiology describing their results, is making and testing new formulations. She has already found promising results using only certain portions of the cell, Del Poeta said.
Del Poeta is also working in drug development. He received a $3 million grant this past December from the NIH for his continued work on drugs to treat fungal infections. Last June, Del Poeta published a study in mBio, the online journal of the American Society for Microbiology, in which he found two compounds, BHBM and its derivative DO, that decreased the level of a lipid fungal cells need to reproduce. Since then, he has found that some derivatives are more potent and less toxic.
He has teamed up with Iwao Ojima, the director of the Institute of Chemical Biology and Drug Discovery at Stony Brook University, and John Mallamo, who was a director in drug discovery at Cephalon. The scientific team is working with Brian McCarthy, an entrepreneur-in-residence, as a part of a new company called MicroRid Technologies. The first milestone in the next three to four years is to raise additional funds for FDA filing and to perform a Phase 1 clinical trial some time between 2018 and 2020.
Del Poeta “exudes optimism” and his “scientific rigor and thoughts are simply first rate,” said Perfect. When he’s not working to stop potentially deadly fungal infections, Del Poeta lives in Mount Sinai with his wife Chiara Luberto, who is studying leukemia at the Cancer Center at Stony Brook, and his sons Matteo, who is 9, and Francesco, who is 6. Originally from Treia, Italy, which is near Florence on the Adriatic coast, Del Poeta worked in a pizzeria when he was younger. He built a brick oven in his backyard, where he hosts neighbors and the families of his sons’ classmates. His favorite pizza, called Amir Pizza after a former talented postdoctoral student in his lab, is a white pizza with extra-thin-sliced white onions, one thin-sliced hard avocado, a generous portion of pistachios and mozzarella.
While the work Del Poeta does has clinical implications, he has no expectations to move to a biotechnology company. “I love what I do,” he said. “If I can make the life of a patient a little better, if I can bring a new drug to the clinic or even contribute a little bit to improve the survival of a patient, I would be so grateful.”

Dr. Huilin Li partners with BNL in Groundbreaking DNA Research
In a partnership with Stony Brook researchers, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have released the first-ever images of the protein complex that unwinds, splits, and copies double-stranded DNA. The electron microscope images offer new insight into how this molecular machinery functions, including new possibilities about its role in DNA “quality control” and cell differentiation. The images and implications are described in a paper published online by the journal Nature Structural & Molecular Biology, November 2, 2015. Rockefeller University scientists also worked in partnership with the project.
“This work is a continuation of our long-standing research using electron microscopy to understand the mechanism of DNA replication, an essential function for every living cell,” said Huilin Li, a biologist with a joint appointment at Brookhaven Lab and Stony Brook University. These new images show the fully assembled and fully activated ‘helicase’ protein complex-which encircles and separates the two strands of the DNA double helix as it passes through a central pore in the structure-and how the helicase coordinates with the two ‘polymerase’ enzymes that duplicate each strand to copy the genome.” Studying this molecular machinery, known collectively as a “replisome,” and the details of its DNA-copying process can help scientists understand what happens when DNA is miscopied-a major source of mutation that can lead to cancer-or learn more about how a single cell can eventually develop into the many cell types that make up a multicellular organism. But no one has produced a real structure of a replisome at any resolution for any organism until now. “All the textbook drawings and descriptions of how a replisome should look and work are based on biochemical and genetic studies,” Li said, likening the situation to the famous parable of the three blind men trying to describe an elephant, each looking at only one part. Those textbook drawings show the helicase moving along the DNA, separating the two strands of the double helix, with two polymerases located at the back where the DNA strand is split. In this configuration, the polymerases would add nucleotides (molecules containing the complementary A, T, G, and C bases of the genetic code) to the side-by-side split ends as they move out of the helicase to form two new complete double helix DNA strands.
To test these assumptions, Li’s group turned to the technique they had previously used to study individual components of the helicase, electron microscopy (EM). Jingchuan Sun, an EM expert in Li’s lab, was essential to the success of the work. He studied samples of replisomes from baker’s yeast cells-a model for all nucleus-containing cells-prepared and provided by Roxana Georgescu in Michael O’Donnell’s research group at Rockefeller University. O’Donnell’s group had previously published biochemical results related to this work. “DNA replication is one of the most fundamental processes of life, so it is every biochemist’s dream to see what a replisome looks like,” Sun said. “Our lab has expertise and a decade of experience using electron microscopy to study DNA replication, which has prepared us well to tackle the highly mobile therefore very challenging replisome structure. Working together with the O’Donnell lab, which has done beautiful functional studies on the yeast replisome, our two groups brought perfectly complementary expertise to this project,” he said. The team’s first-ever images of an intact replisome revealed that only one of the polymerases is located at the back of the helicase. The other is on the front side of the helicase, where the helicase first encounters the double-stranded helix. This means that while one of the two split DNA strands is acted on by the polymerase at the back end, the other has to thread itself back through or around the helicase to reach the front-side polymerase before having its new complementary strand assembled. The scientists were so surprised by this finding that they asked another group at Rockefeller, led by Brian Chait, to perform additional structural studies using mass spectrometry. Yi Shi, a postdoctoral fellow in Chait’s group performed this work, which confirmed the electron-microscopy-based conclusion about the unexpected architecture of the replisome.
The counterintuitive position of one polymerase at the front of the helicase suggests that it may have an unforeseen function. The authors suggest several possibilities including keeping the two “daughter” strands separate to help organize them during replication and cell division. It might also be possible that, as the single strand moves over other portions of the structure, some “surveillance” protein components check for lesions or mistakes in the nucleotide sequence before it gets copied-a sort of molecular quality control.
This architecture could also potentially play an important role in developmental biology by providing a pathway for treating the two daughter strands differently. Many modifications to DNA, including how it is packaged with other proteins, control which of the many genes in the sequence are eventually expressed in cells. An asymmetric replisome may result in asymmetric treatment of the two daughter strands during cell division-an essential step for making different tissues within a multicellular organism.
As the paper concludes, “Clearly, further studies will be required to understand the functional implications of the unexpected replisome architecture reported here.”
One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security.

The ACS International Chemical Sciences Chapter in Shanghai put on a winner with the 1st International Symposium of Chemistry & Life Sciences, held on Oct. 16–17 in Jiangyin, in Jiangsu province, China. With about 125 attendees, the meeting highlighted the challenges and opportunities in drug discovery for cancer and infectious diseases. An international slate of speakers, led by Nobel Laureate and Harvard University emeritus chemistry professor E. J. Corey, described trends and new approaches to discovering drugs for cancer and infectious diseases. “Infectious diseases and cancer are two major disease classes in China,” said Jingye Zhou, a principal scientist at the Lilly China R&D Center and the chair of the ACS Shanghai chapter. “The symposium shone some light on the R&D work that could help patients in China and worldwide.” The chapter partnered with the E. J. Corey Institute of Biomedical Research (CIBR), in Jiangyin, in organizing the meeting. CIBR is a nonprofit research organization nominally founded by Corey and a group of Chinese returnees and funded by the Jiangyin local government and Jiangsu province. Its mission is to make a difference in the treatment and diagnosis of disease, specifically tuberculosis. In presenting a “superoverview” of cancer, Corey described the disease as caused by cascading dysregulation when things go wrong in the highly ordered, very low entropy system that is the human body. “Cancer is an inevitable condition because of the imperfections of the body transiting from one state to another,” he said. “If we all were to live to a very old age and had otherwise perfect health, we would die of cancer.” The ultimate advance—the real prize—he said, is rapid methods for early diagnosis. The symposium was “excellent” and “very interesting,” Corey told C&EN. “The folks in Jiangyin are delighted to have a connection with ACS. They see ACS as a premier organization that gives them a link to the outside world.” “Many scientists in China are unable to attend ACS national meetings due to logistic hurdles,” Zhou told C&EN. “By creating a local ACS organized symposium, we brought topnotch scientific exchange to a broad community in China. The symposium also enabled local ACS members to network with each other and with international speakers.” (Copied from C&EN)

Stony Brook Researchers Quantify Underlyinglandscape of Cancer
The cellular and genetic hallmarks of cancer development are multiple, and a team of researchers in the Departments of Chemistry and Physics at Stony Brook University have developed a pictorial yet quantitative landscape theory to explore cancer cellular development that could form the foundation to new anticancer tactics. Their research and methods used are published in two new scientific papers. One is published in the Proceedings of the National Academy of Sciences (PNAS) early edition and titled “Landscape and flux reveal a new global view and physical quantification of mammalian cell cycle,” and the other is published in the Journal of the Royal Society Interface and titled “Quantifying the underlying landscape and paths of cancer.” In the PNAS paper, the researchers considered one of the hallmarks of cancer – the cell cycle. The cell cycle speed of cancer is much faster than normal cells. By quantitatively uncovering the landscape of the cell cycle, the researchers are able to visualize the cell cycle progress and illustrate its journey along a “ring valley” with hills and valleys. By showing this unconventional view of the cell cycle quite different from standard texts, they discovered two major forces for the cell cycle: the cycle flux as the driving force originated from the nutrition supply for accelerating cell cycle and the barriers from the “hills and valleys” as the dragging force for decelerating cell cycle. “By identifying two cell cycle driving forces, and the key genes and regulations influencing these forces, we believe this could be the basis for an anti-cancer targeting strategy that targets these key genes and regulations, as well as the nutrition supply to reduce the cell cycle speed from fast cancer back to normal cell speed,” explained Prof. Jin Wang, PhD, a faculty member in the Department of Chemistry, an adjunct faculty member in the Department of Physics, and a member of the Laufer Center for Physical and Quantitative Biology, and a member of the Institute of Chemical Biology and Drug Discovery. In the Journal of the Royal Society paper, the research team developed a global potential landscape and path framework to quantify cancer and associated processes, all of which involves the interaction of genes. In this conceptual and quantitative picture, the cancer and normal cells can be viewed as different basins of a landscape. The landscape topography characterizes important biological states, such as normal, cancer, and cancer cell proliferation. “In this case we are uncovering multiple hallmarks of cancer, not just one, and with that we can identify the key genes and regulations determining the depths of cancer and normal basins as well as the transition barriers in between,” said Professor Wang. “The landscape shape can be used as a potential way to design anti-cancer strategies by targeting multiple genes and gene regulation patterns.” Prof. Wang, and his Stony Brook post-doctoral researcher and co-author Dr. Chunhe Li of the Department of Chemistry, along with scientific collaborators in China will continue the research in order to build and refine quantitative models of the cellular landscape of cancer. The combined research is supported by the National Science Foundation and the National Science Foundation of China. (copied from the SBU news)
ICB&DD congratulates Dr. Scott Laughlin for receiving a National Science Foundation Award for Brain Initiative Research. The National Science Foundation (NSF) has awarded Dr. Scott Laughlin, an Early Concept Grant for Exploratory Research (EAGER). The EAGER awards are part of the foundation’s support of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, a multi-agency research effort that seeks to accelerate the development of new neurotechnologies that promise to help researchers answer fundamental questions about how the brain works. In March of this year, NSF asked researchers to submit ideas for early-stage, potentially ground-breaking new approaches to reveal how neuronal processes in the brain lead to complex behaviors in any organism. NSF reviewed the summaries and invited full proposals from applicants whose ideas best aligned with the outlined research topics. Dr. Laughlin, ICB&DD Project Member and Assistant Professor in the Department of Chemistry at Stony Brook, was among 36 recipients of these EAGER awards. Each EAGER award is for $300,000 over a two-year period, and award recipients will apply this funding to develop a range of conceptual and physical tools, from real-time whole brain imaging, to new theories of neural networks, to next-generation optogenetics. Dr. Laughlin will apply the grant funds to an investigation of the use of synthetic molecules for mapping the connections between neurons in the brain.

From the Lab Bench to the Computer
Brian Ralph ’15 combines two approaches to researching innovative pain medication
A passion for both science and math has been a boon for undergraduate Brian Ralph, catapulting him to the crossroads of a major multidisciplinary research project. Since joining the team at theInstitute for Chemical Biology and Drug Discovery (ICB&DD) at Stony Brook, Brian has worked with researchers in Biochemistry and Cell Biology, Chemistry, Applied Mathematics and Statistics, and Anesthesiology to develop new pain medications that will work by elevating the levels of natural painkillers in the body. “It’s a great group,” says Brian, a member of the Honors College who is a biology major with a concentration in quantitative biology and bioinformatics — in his words “a bit of a crossover between biology and math.” Now a junior, Brian has been working in Dale Deutsch’s biochemistry lab since his freshman year. Deutsch, Professor of Biochemistry and Cell Biology in the College of Arts and Sciences, and his associates are studying new classes of inhibitors that temporarily stop the action of Fatty Acid Body Proteins (FABPs) present in our cells. The result of this inhibition is an artificial elevation in the natural painkillers — called endocannabinoids — that exist in our bodies. Drugs that may eventually be developed from this research will not be addictive, which is a common problem with the opioids now widely used.
Last month, the ICB&DD received a $3.8 million grant from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), to continue its groundbreaking work. Led by Principal Investigator Deutsch, other members of the team include Iwao Ojima, Distinguished Professor of Chemistry and Director of the ICBⅅ Martin Kaczocha, a former post-doctoral fellow in Deutsch’s lab who is now an Assistant Professor in the Department of Anesthesiology; Robert Rizzo, Associate Professor of the Department of Applied Mathematics and Statistics; Bill Berger, a PhD candidate in Ojima’s lab; Huilin Li, a biochemist in both the Department of Biochemistry and Cell Biology and at Brookhaven National Lab; and the Laufer Center for Quantitative and Physical Biology.
To tackle the project from another direction, Brian also works in Rizzo’s lab using software that allows him to visualize and manipulate the FABP protein structures in three-dimensional space. “Different laboratories have different approaches to the same research,” explains Brian. “In Dale’s lab we take a biological approach, and here it’s more of a computational or structural approach.”
In December 2012 Brian co-authored a paper based on the team’s research with Berger and Koczocha in PlosOne. He is also co-author, along with Kaczocha, of a second paper submitted to PlosOne for review. Brian started doing research when he was a student at Smithtown High School West as part of Stony Brook’s Simons Summer Research Program, when he worked with Alan Turner in the Department of Anatomical Sciences. His work in the Deutsch lab has been supported by URECA and a Harvard Lyman award. Brian is a member of both the Undergraduate Biochemistry Society and the Undergraduate Biology Advisory Board.
With the goal of becoming a dentist, Brian is also active in Stony Brook’s Pre-dental Society and has shadowed pediatric dentists and oral surgeons. Will he combine research and dentistry someday? “That’s still up to debate,” says Brian. “I love dentistry. It’s something that’s become very close to me. And while I wish to pursue dentistry, I definitely want to continue with research in the future because it has been such a big part of my life.” In his spare time, Brian plays the cello in Stony Brook’s undergraduate orchestra. He also enjoys cycling and running and is training for a triathlon next spring. “In the end, I would love to live a modest life as a dentist,” he says. “Something where I’d be able to enjoy my life and what I do every day. I’d also like to be able to contribute to the ongoing questions in science and research as part of a lab. And, of course, someday I would love to see Stony Brook’s FABP inhibitor on the market. “You never know. Five, ten years from now, maybe we’ll have advances that can put it through clinical trials, and we’ll see where it goes from there. I’d love to see our whole lab group — the ICB&DD’s — name on a pain inhibitor, something as common as aspirin, hopefully.” (copied from the SBU news by Toby Speed.)
ICB&DD welcomes Dr. Scott T. Laughlin as a Project Member. Dr. Laughlin is an Assistant Professor in the Department of Chemistry. Dr. Laughlin’s research uses chemistry to examine how the brain works. How does the brain sense the environment? How does it decode that sensory information and control behavior? All of the brain’s many functions rely on its neural circuits—a complex web of neurons connected to each other in such a way that they can perform the logical operations that allow us to think, respond to stimuli, etc. Precisely how neural circuits perform their calculations is a mystery whose solution has wide ranging implications for human health. Using organic synthesis, molecular biology, and behavioral neurobiology, he creates chemical tools to help reveal the structure of neural circuits in living animals. Dr. Laughlin’s received his Ph.D. (2008) in Chemistry and Chemical Biology from University of California, Berkeley. He completed his postdoctoral research fellowship in the Department of Molecular and Cell Biology at University of California, Berkeley in the laboratory of Professor John Ngai (2008-2013). Dr. Laughlin has an exceptionally strong background in chemistry and neuroscience. He is exploring the interface of chemistry and neurobiology, i.e., "chemical neurobiology". He is one of the "Chemical Biology Initiative" hires at the Chemistry Department and started this past September. Dr. Laughlin will be an excellent addition to the Chemical Biology Training Program and will lead the establishment of Chemical Neurobiology Program at ICB&DD.
ICB&DD welcomes Dr. Ming-Yu Ngai as a Project Member. Dr. Ngai is an Assistant Professor in the Department of Chemistry. Dr. Ngai’s research focuses on developing novel and practical synthetic methodologies to address unmet challenges in organic synthesis and medicinal chemistry, and (ii) identifying and developing new radiotracers for Positron Emission Tomography (PET) imaging to elucidate disease mechanisms, identify drug targets, assess treatment efficacy, and accelerate drug discovery and development. Dr. Ngai’s research interests are multidisciplinary, covering organic and organometallic chemistry, photochemistry, radiochemistry, and biomedical imaging. Dr. Ngai received his Ph.D. (2008) in Chemistry from University of Texas, Austin. He was awarded a Croucher Foundation Postdoctoral Research Fellowship at Stanford University and worked in the laboratory of Professor Barry M. Trost (2009-2011). He also performed postdoctoral research at Harvard University in the laboratory of Professor Tobias Ritter (2011-2013). Dr. Ngai has an exceptionally strong background in chemical synthesis and will apply it to molecular imaging for diagnosis and therapy. He is one of the "Chemical Biology Initiative" hires at the Chemistry Department and started this past September. Dr. Ngai will be an excellent addition to cancer and infectious diseases research programs, as well as chemical biology training program.
Congratulations to the ICB&DD team, consisting of Drs. Dale Deutsch (PI) Department of Biochemistry, Iwao Ojima (Co-PI) Department of Chemistry, Robert Rizzo (Co-PI) Department of Applied Mathematics and Statistics, Huiling Li (Co-PI) Department of Biochemistry and Martin Kaczocha (Co-PI) Department of Anesthesiology, School of Medicine on receiving a research award from the National In
stitutes of Health, National Institute of Drug Abuse. This ICB&DD multidisciplinary research team has received a five-year $3.8 million grant for the project entitled “Anandamide Transport Inhibitors”. The main focus of this grant is to develop new drugs, inhibiting recently discovered anandamide transporter, for pain, stress and issues with drug addiction and withdrawal. Anandamide is a neurotransmitter that occurs naturally throughout the body for regulation of pain and stress. This is a very exemplary multi-disciplinary research project of productive collaborative efforts among faculty and ICB&DD. Initial funding for the research began with a SBU-BNL seed grant to Dr. Deutsch and Dr. Li from Stony Brook University and Brookhaven National Laboratory in 2010, followed by a Stony Brook University School of Medicine Targeted Research Opportunities (TRO) Fusion award to Drs. Deutsch, Li, and Ojima as well as a New York State SUNY REACH grant for Drs. Deutsch and Haj-Dahmane. Dr. Deutsch also received a previous single investigator grant from the NIH to research FABPs. - See more at:

ICB&DD congratulates Dr. Iwao Ojima for being named as the recipient of the 2013 American Chemical Society (ACS) Award for Creative Work in Fluorine Chemistry! Dr. Ojima is cited “for his outstanding contributions to fluorine chemistry through his pioneering and creative research in synthetic methodology and biomedical applications.” Dr. Ojima’s research, a combination of both transition metal catalysis and medicinal chemistry, has had a profound impact on the fluorine chemistry at the biomedical interface. This is his third ACS National Award in addition to the Arthur C. Cope Scholar Award (organic chemistry) in 1994 and the E. B. Hershberg Award (drug discovery and medicinal chemistry) in 2001, illuminating the exceptional breadth and excellence in his research. Dr. Ojima first introduced catalytic processes into organofluorine chemistry in the early 1980s, and developed highly-efficient methods for the practical synthesis of optically active fluoro-amino acids by means of catalysis and enzymatic resolution. His invention of a highly efficient process for the synthesis of 5-trifluoromethyluracil was commercialized for the production of trifluridine (antiviral drug). He developed successful fluorine-containing molecules for the treatment of high blood pressure and as pain killers. Most recently, he synthesized taxol derivatives containing fluorine as anticancer agents, probes of chemical and structural biology, and to enhance drug potency.

The instrument consists of a 1260 uPLC, a TOF mass analyzer and a UV-Vis diode-array detector (DAD). The DAD provides wavelength measurements from 190-800nm with a 20Hz acquisition rate. The mass spectrometer is a G6224A oaTOF model. It provides MS capabilities in the range m/z=100-20,000. It is typically operated in MS mode in the range m/z=100-3200 while maintaining a resolution of 20,000 at m/z= 1,522 and acquiring 20 spectra/sec with an accuracy of <2 ppm. The instrument has two possible ionization sources: 1) an ESI source and 2) a MultiMode source consisting of combined ESI and APCI ionization modes. Both sources have dual inlets allowing for internal reference mass calibration to achieve <2ppm mass accuracy. The instrument is used exclusively for accurate mass determination, formula verification (HRMS) and sample purity analysis for small molecules and biopolymers. The new Agilent LC-UV-TOF is located in Room 570 of the ICB&DD Analytical Chemistry Laboratory. The acquisition of this instrument was made possible by a generous research support from the Reata Pharmaceuticals to ICB&DD through Dr. Honda (Director, ICB&DD Anti-inflammatory Research Laboratory) and a matching fund from the SBU Office of the Vice-President for Research.

Stony Brook University and Sanofi have announced amulti-year research collaboration with an option to a world-wide license to compounds resulting from the ICB&DD Director, Dr. Ojima’s work on FtsZ inhibition as a potential treatment for Tuberculosis (TB) and other bacterial infections. TB is a lethal and highly contagious infectious disease caused by Mycobacterium tuberculosis. TB is second only to HIV as the most deadly infectious disease. TB is transmitted through the air and may lay dormant in the body in a latent state. It is estimated that one third of the world’s population is infected with latent TB and approximately 12 million people suffer from active infection. Once active, TB is spread through the air by coughing and sneezing. TB is treated with a cocktail of antibiotics over the course of 6 months or more, making it a long, complicated and difficult to follow treatment regimen. Not adhering to the treatment course can lead to the development of multiple drug resistant TB (MDR-TB). Therefore, new drug targets and treatments are needed to shorten treatment times and improve reatment outcomes. Dr. Ojima and his team at ICB&DD have discovered novel compounds that inhibit bacterial cell division by interfering with a critical cellular protein called FtsZ. The FtsZ is responsible for forming a contractile ring within the bacteria that is essential for cell division. By interfering with FtsZ assembly, the bacteria are unable to maintain, divide and propagate. Dr. Ojima’s team at ICB&DD will work with Sanofi to optimize these novel benzimidazole-based compounds with the objective to identify drug candidates ready for translational drug development. ICB&DD is very excited to work with Sanofi, a world leading pharmaceutical industry, including therapeutics for TB and other infectious diseases. This collaboration demonstrates ICB&DD’s innovative approach to finding solutions to unmet medical needs.
