ICB&DD Member's Research Highlights

2018 Highlights

Spin-off companies

Chronus Pharmaceuticals, Inc.
The Chronus Pharm. (Dr. Nicole Sampson, President) acquired a Phase 1 NIH/STTR grant for pediatric TB diagnostic feasibility work. LI BioHub REACH Proof of Concept grant was acquired, as well. Also, the Chronus Pharm. was selected as a StartupNY company by the NYS Governor’s Office. The CEO (Dr. Labros Meimetis) has been appointed.

 MicroRid Technologies, Inc.
Dr. Maurizio Del Poeta founded “MicroRid Technologies Inc.” together with Brian McCarthy (CEO) and John Mallamo (CRO). The company is developing a new class of antifungal agents targeting the synthesis of fungal glucosylceramide with ICB&DD’s Discovery Chemistry
Lab. It is also currently developing a new ceramide synthase assay for the screening and identification of a specific fungal ceramide synthase inhibitor(s).

CuraMir Therapetuic, Inc.
CuraMir Therapeutic, Inc. was established in 2018 founded by Dr. Jingfang Ju. The mission of the company is to develop novel miRNA based cancer therapeutics to improve qualify and extend patient life. The company has licensed several miRNA platform
technologies from Stony Brook University. 

Targagenix Inc.
As reported previously, Targagenix (CEO: James Eagan, Ph.D., MBA from SBU) licensed PUFA-Taxoid anticancer drug conjugates (Inventor: Dr. Ojima) from the Research Foundation of SUNY to develop these drug candidates. An NCI Contract was granted for the development of NE-PUFA-taxoids (nanoemulsion formulation of PUFAtaxoid conjugates) (Targagenix-SBU-Northeastern Univ. consortium). The project has been moving well and pre-IND feedback from FDA was encouraging and informative. Grant applications and VC fund acquisition have been actively ongoing.

Drug Discovery and Development

 Dr. Nicole Sampson is developing azasteroids for treatment of tuberculosis. Cholesterol metabolism is important for persistence of Mycobacterium tuberculosis (Mtb) in mouse models of infection. Dr. Sampson’s group identified lead compounds that show excellent
antibacterial activity against M. tb. The inhibitor scaffold has high host in vivo stability, low host toxicity, and excellent host bioavailability. A lead compound has good bioavailability and is accumulated in the mouse lung, as well as shows no sign of
potential drug-drug interaction by in vitro tests. She assumed the President of Chronus Pharmaceuticals, Inc.  Dr.  Nicole Sampson is also developing a method for early detection of TB. The diagnosis rate of childhood TB is very low due to the lack of accurate diagnostic methods for children who cannot produce sputum samples. Her group identified a modified serum lipoprotein (MtLDL) that results from exposure to Mycobacterium tuberculosis, and have established an ELISA assay using anti-MtLDL mAbs that are being developed as a minimally invasive, robust, serum-based diagnostic tool to detect active tuberculosis. She obtained NIH REACH grant, as well as an STTR grant through Chronus Pharm.  CPI-613, a novel “altered energy metabolism directed (AEMD)” anticancer drug invented
by Dr. Bingham, which was licensed to and being developed by the Cornerstone Pharmaceuticals, has reached Phase II human clinical trials for AML, MDS and solid tumors. Also, it is in Phase I and I/II for several indications and combinations, including
FOLFIRINOX (folic acid + 5-FU).

 Development of NE-DHA-SBT-1214 by TargaGenix, Inc. (Dr. James Egan), based on Dr. Iwao  Ojima’s invention of DHA-taxoids in combination with the unique nanoemulsion technology developed by Dr. Amiji (Northeastern Univ.), against CSC-initiated tumor xenografts are moving well. IND filing is in sight. Combination with anti-PDL-1 antibody exhibited a synergistic effect on highly challenging pancreatic cancer (PDAC) in vivo. 

 Dr. Jarrod French’s laboratory is developing novel Sts-1 inhibitors for deadly pathogen infections through structure-based drug discovery approach. This project/invention has secured a drug discovery grant from DOD, Fusion award from SOM and REACH grant
from NIH.

Dr.  Kenneth Shroyer and Dr. Luisa Escobar-Hoyos discovered that keratin 17 (K17) protein and mRNA serve as excellent prognostic biomarkers for patient survival, independent of tumor grade and stage in triple-negative breast, cervical and pancreatic cancers. They also defined
binding domains that mediate K17 interaction with p27 and made K17 as druggable target. This team received the 2018 Pancreatic Cancer Action Network (PanCAN) Translational Research Award to further promote this project.

Dr.  Jingfang Ju’s invention on novel miR-129 derivatives, bearing 5-FU in place of U units in the sequence show early promise as totally new approach to gene-based chemotherapy. A US Patent application was filed. Three more NTDs have been filed, which will lead to
patent applications. To pursue miRNA-based cancer therapeutics development, CuraMir Therapeutics, Inc. was founded.

Baldoxolone methyl (BARD), invented by Dr. Tadashi Honda, is undergoing two Phase III studies: (i) for connective tissue disease-associated pulmonary arterial hypertension (CTD-PAH) by Reata Pharmaceuticals, Inc. and (ii) for diabetic nephropathy by Kyowa Hakko Kirin.
Both cases showed excellent Phase II and Phase IIb results. Reata is currently conducting a global Phase 3 clinical study on BARD in connective tissue disease associated PAH and a global Phase II/III clinical study in Alport syndrome. 

A tricyclic cyanoenone, TBE-31, invented by Dr. Tadashi Honda, is an another Nrf2 activator, and has various features that BARD does not have. His team found that TBE-31 reverses high-fat diet and fructose-induced nonalcoholic steatohepatitis (NASH) in an Nrf2-
dependent manner. Since currently there are no treatments for NASH other than lifestyle changes, their findings offer hope to patients with NASH.

Dr. Maurizio Del Poeta’s laboratory has identified fungal ceramide synthase as novel drug target, and found a few hit compounds through HTP screening. Then he started collaboration with Dr. Iwao Ojima and ICB&DD’s Drug Discovery Lab. for hit-to-lead optimization. A large
size NIAID grant has been secured and three patent applications were filed and two WO patent applications were published. These compounds will be licensed to MicroRid Inc.

Development of novel fatty acid binding protein (FABP) inhibitors as new type of analgesic and anti-inflammatory agents, based on the lead compound, SB-FI-26, is moving well, a new PCT patent application for optimized compounds, exhibiting higher potency as well as sub-type selectivity, was filed. The FABP targets and FABP inhibitors were licensed to the Artelo Biosciences and preclinical drug development has been actively ongoing.

Dr. Peter Tonge developed [18F]F-PABA, a fluorine-18 analog of p-aminobenzoic acid. [18F]FPABA is able to defect and quantify bacterial infection in a soft tissue model of S. aureus infection using PET imaging. A Phase 1 STTR grant to evaluate [18F]F-PABA in a
preclinical model of prosthetic joint infection was obtained through Chronus Pharm. 

Dr. Lori Chan identified Skp2 E3 ligase as excellent drug target in castration-resistant prostate cancer and a hit compound was identified by HTP assay. A collaboration with  Dr. Jin Wang and Dr. Iwao Ojima for hit-to-lead optimization has led to the identification
of highly potent lead compounds, which will be further optimized.

 Dr. Jarrod French’s laboratory is developing novel Sts-1 inhibitors for deadly pathogen infections through structure-based drug discovery approach. This project/invention has secured a drug discovery grant from DOD, Fusion award from SOM and REACH grant
from NIH. In addition, he received an NIH R21 grant on this drug discovery project.

Biomarkers and Targets

 Keratin 17 was discovered in Dr. Kenneth Shroyer’s laboratory as diagnostic and prognostic biomarkers for cervical intraepithelial neoplasia (CIN) and squamous-cell carcinoma (SCC). Now, Keratin 17 was also validated as a highly sensitive and specific biomarker
for prognosis of pancreatic cancer. Two US Patent applications were filed and published (US20160187341A1, US20180340935A1). In addition, MR spectroscopy models were developed to evaluate metabolic properties impacted by keratin 17 in mouse xenograft
models of pancreatic cancer.

The miRNAs, miR192 and miR215, identified i n Dr.  Jingfang Ju’s laboratory, would serve as new biomarkers in cancer diagnosis and prognosis in colorectal, gastric and endometrial cancers. These miRNAs would also provide excellent targets for novel anti-cancer therapeutics. 

RNF8 E3 ligase was discovered by Dr. C.-H. Chan as a novel cancer stem cell (CSC)/EMT activator and drug target. Dr. Chan also discovered Skp2 E3 ligase as excellent drug target in castration-resistant prostate cancer.  

 Fatty acid binding proteins (FABPs) discovered by Dr. Dale Deutsch’s laboratory are excellent targets for anti-inflammatory and analgesic drug discovery. It has been shown by ICB&DD Team (Deutsch, Kaczocha, Ojima, Rizzo and Li) that the inhibition of FABPs
increases the anandamide level, leading to potent anti-nociceptive effects. In addition, the inhibition of FABP5 and FABP7 have been shown to lead to tumor suppression, and thus FABP inhibitors can be developed for cancer therapy, as well.

FadA5, a flavin adenine dinucleotide and a thiolate from M. tuberculosis was identified by  Dr.  Nicole Sampson to be a new target for anti-TB drug discovery. Structural comparisons to human thiolases revealed that it should be possible to target FadA5 specifically and the
steroid-bound structure provides a solid basis for the development of inhibitors against FadA5.

Dr. Jian Cao has found that the hemopexin domains of MMP9 and 14 are key functional components of these MMPs, which are required for cancer cell migration and invasion. Thus, these hemopexin domains would provide excellent targets for cancer chemotherapeutics to block cancer metastasis.

The V777L and other activated mutant forms of ErbB2 were identified by Dr. Todd Miller as potential target for drug discovery for breast cancer chemotherapy.

Biliverdin reductase B (BLVRB) is considered an excellent target for the development of drugs for oxidative stress-mediated diseases. Dr. Wadie Bahou and Dr. Jin Wang are screening inhibitors of BLVRB.

Cancer initiating cells (CICs), obtained by isolation from clinical samples and cultivation ( Dr. Galina Botchkina, colon and prostate cancers), have been successfully used to produce tumor xenografts in nod-scid mice. These tumor xenografts are essential for drug
discovery targeting CICs.

Phosphoinositide 3-kinase (PI3K) isoform, p100, identified in Dr. Richard Lin’s laboratory, is a potential target for a novel therapy for the treatment of pancreatic cancer, either by targeted therapy or in combination with standard chemotherapy.

Serine hydrolases in the mycobacterial cell wall were identified in Dr. Jessica Seeliger’s laboratory as novel targets for possible intervention of TB by small-molecule inhibitors.
