Use of NCGC00117362, NCGC117328, NCGC00117505, NCGC00117477 and NCGC00117166 for the Treatment of Ovarian Cancer

This technology includes the use of a chemical series (compounds NCGC00117362, NCGC117328, NCGC00117505, NCGC00117477, NCGC00117166 and their analogs) as potential treatment for ovarian cancer. These compounds were identified through a high throughput screen (HTS) of 44,806 compounds implemented at NCATS using a layered 3D organotypic assay model of human ovarian cancer metastatic microenvironment containing primary human mesothelial cells, primary human fibroblasts, and extracellular matrix.

RALDH1 Inhibitors for the Immunotherapy of Hepatocellular Carcinoma

This technology includes the utility of the novel small molecule inhibitors of ALDH1A1 (RALDH1) in combination with immunotherapy for the treatment of hepatocellular carcinoma (HCC). Recently it was shown that the ALDH1A1 catalyzed production of retinoic acid (RA) in tumor cells promotes their differentiation into immunosuppressive antigen-presenting cells. Therefore, blocking RA production by tumor cells and/or blocking RA signaling in monocytes using our ALDH1A1 inhibitors can alleviate immunosuppression and engender anti-tumor immune responses.

Cell-based High-throughput High-content Assays Using Glycolytic Enzymes for Drug Discovery

This technology includes an assay capable of monitoring glycosome formation for use in high throughput screening (HTS). The reversible assembly and disassembly of a multi-enzyme complex, known as the glycosome, visualized by GFP-labeled human phosphofructokinase-1 (PFK1), is employed as an intracellular marker in human cells to screen small molecule libraries under high-content imaging in a high-throughput fashion. The glycolytic enzymes have been proposed to form a multi-enzyme complex in the cell.

Discovery of DPTIP a Small Molecule Inhibitor of Neutral Sphingomyelinase 2 (nSMase2) for the Treatment of Neurodegenerative and Oncologic Diseases

This technology includes a newly discovered molecule 2,6-Dimethoxy-4-(5-Phenyl-4-Thiophen-2-yl-1H-Imidazol-2-yl)-Phenol (DPTIP) as potent inhibitor of neutral sphingomyelinase 2 (nSMase2), to be used for the treatment of neurodegenerative and oncologic diseases. This discovery was identified through unbiased screening of the National Center for Advancing Chemical Sciences (NCATS) chemical library using our human neutral sphingomyelinase assay.

Nrf2 Inhibitors for the Enhancement of Cancer Chemotherapy and Radiotherapy

This technology includes the identification of small molecule inhibitors of nuclear factor erythroid-2 related factor-2 (Nrf2) as therapeutic anticancer agents. Multiple mechanisms lead to frequent dysregulation of Nrf2 activity in cancer cells, which promotes both tumorigenesis and therapeutic resistance. Dysregulated Nrf2-Keap1 pathway is a novel determinant of chemoresistance/radioresistance and inhibition of Nrf2 signaling will enhance the efficacy of chemotherapeutic and radiotherapy.

Mutant IDH1 Inhibitors for Cancer Treatment

This technology includes a novel chemotype against mutant (R 132H) isocitrate dehydrogenase 1 (IDH1) enzyme to be utilized as an anticancer therapy. We have progressed the structure activity relationship (SAR) and optimized the compound to be low nanomolar inhibitor of the enzyme with low nanomolar inhibition of the target in cells. These compounds lower 2-hydroxyglutarate, which has been termed an 'oncometabolite' and is common in a subset of cancers including glioma, cholangiocarcinoma, chondrosarcoma and acute myeloid leukemia.

Galactose Kinase (GALK) Inhibitors for the Treatment of Galactosemia and Other Disorders of Galactose Metabolism

This technology includes selective inhibitors of the human enzyme galactokinase (EC 2.7.1.6), which may be useful for the treatment of Galactosemia and other diseases caused by aberrant galactose metabolism, including cancer. These compounds inhibit the first step in galactose metabolism, thereby eliminating the build-up of toxic metabolites during the aberrant metabolism of galactose, as well as inhibitor the entry of galactose into glycolysis and other downstream assays.

Identification and Use of Heterocyclic Alcohol Compounds for the Treatment of SULT1A1-expressing Cancers

This technology includes the identification and use of heterocyclic alcohol compounds, including RITA and N-BIC, for the treatment of SULT1A1-expression cancers. A high-throughput screen (qHTS) was performed using >1,000 caner cell lines identified a compound called YC-1 (also called Lificiguat) that is effective across cancer cell types that express the phase 2 detoxifying enzyme SULT1A1.

Inhibitors of Eya2 Phosphatase as an Anticancer Therapy

This technology includes inhibitors of the Eya phosphatase which can be utilized as anticancer therapy. The Eya proteins are essential co-activators of the Six1 transcription factor, a gene that is abnormally re-expressed in a large percentage of breast cancers. This over-expression plays a causal role in the initiation and metastatic development of breast cancers. The Eya family of proteins was also found to contain a unique haloacid dehalogenase phosphatase domain with protein Tyr phosphatase activity which can potentially play a role in Six1- mediated breast tumorigenesis.
