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.

Preparation of Benzene-1,4-disulfonamide Derivatives Useful as Therapeutic TRPML1 Receptor Modulators for the Treatment of Lysosomal Dysfunction and Membrane Repair Disorders

This technology includes a series of novel benzene-1,4-disulfonamides that activate TRPML1 receptor. The TRPML1 receptor is a lysosomal Ca2+ channel that has been shown to be involved in controlling lysosome functions, among then the maintenance of the integrity of the plasma membrane and the modulation of autophagosome-lysosome fusion. The improved ability of the receptor to deliver Ca2+ ions to the cytosol had been correlated with its capacity to modulate autophagy and lysosome exocytosis.

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.

Small Molecule Inhibitors of Clk and Dyrk Kinases for Potential Therapeutic Intervention of Down Syndrome, Alzheimer's Disease and Cancer

This technology includes small molecule inhibitors of the cdc2-like kinase (Clk) and Dyrk kinase which can restore splicing outcomes within many dysregulated splicing events potentially reversing phenotypes associated with diseases associated with abnormal splicing. The Clks regulate the alternative splicing of microtubule-associated protein tau and are implicated in frontotemporal dementia and Parkinson's disease through the phosphorylation of splicing factors (SF).

Small Molecule BET Bromodomain Inhibitors for the Treatment of Cancer and Inflammatory Diseases

This technology includes a new chemical series of substituted bicyclic heteroaryl small molecules as potent bromodomain-containing protein BRD4 inhibitors used for the treatment of cancer and inflammatory diseases. The optimization led to compounds with good potency in enzymatic assay ( 100 nM) and in MV4-11 cell-based assay ( 1000 nM) as well as excellent early ADME properties. We also identified N-methyl 2 pyridone and N-methyl pyrrolopyridone are great replacements of di-methylisoxazole. This chemical series also exhibited good ADME profiles, including PK.

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.

Inhibitors of 3-phosphoglycerate Dehydrogenase as an Anticancer Therapy

This technology includes a family of inhibitors of 3-phosphoglycerate dehydrogenase (PHGDH) which could be utilized as a treatment for cancer. These compounds are based on a carbiothioamide core and represent the first chemotype capable of inhibiting this enzyme. The compounds have in vitro IC50s of 1-5 uM and exhibit selective cytotoxicity towards PHGDH-overexpressing cell lines of ~10 uM. They exhibit at least an order of magnitude lower toxicity towards cell lines that do not express PHGDH.
