Methotrexate Analogs with Enhanced Efficacy and Safety Profile

Scientists at NCATS have developed an analog of Methotrexate (MTX) that incorporates the proteasome-targeting properties of E3-ubiquitin ligase small molecule ligands (MTX-PROTACs) to directly bind to the MTX target dihydrofolate reductase (DHFR) and mark the protein for proteasomal degradation. This unique property may dramatically lower the therapeutic dose required in a treatment setting.

Real-time Cellular Thermal Shift Assay and Analysis (RT-CETSA) for Research and Drug Discovery

Scientists at NCATS have developed a novel Cellular Thermal Shift Assay (CETSA), named “Real-time CETSA” in which temperature-induced aggregation of proteins can be monitored in cells in real time across a range of compound concentrations and simultaneously across a temperature gradient in a high-throughput manner. Real-time CETSA streamlines the thermal shift assay and allows investigators to capture full aggregation profiles for every sample.

Substituted Quinoline Analogs as Aldehyde Dehydrogenase 1A1 (ALDH1A1) Inhibitors

Aldehyde dehydrogenase enzymes (ALDHs) have a broad spectrum of biological activities through the oxidation of both endogenous and exogenous aldehydes. Unbalanced expression levels of ALDHs have been associated with a variety of disease states such as alcoholic liver disease, Parkinson’s disease, obesity, and multiple types of cancers. ALDH1A1 also plays a major role in preserving the tumor microenvironment via differentiation, self-protection, and proliferation of cancer stem cells.

Use of Auranofin for the Treatment of Chronic Lymphocytic Leukemia (CLL)

This technology includes the use of auranofin for the treatment of Chronic Lymphocytic Leukemia (CLL). Auranofin is currently approved for the treatment of rheumatoid arthritis and has been shown to display anti-cancer activity. CLL is a blood and bone marrow disease that usually progresses over a lengthy period of time and normally occurs in middle-age adults. The current therapeutic options for CLL patients are limited, and there are few therapies under development.

Generation of Anti-TAT FXN Polyclonal and Monoclonal Antibodies to TAT Domain for Use in Quantitating or Detecting TATFrataxin (TAT-FXN) and Analogs

This technology includes a strategy to generate antibodies of rabbit origin, both polyclonal and monoclonal, which have strong affinity to the TAT sequence and which enable specific immunocapture or immunodetection of TAT containing frataxin and analogs for quantitative or qualitative assays. In addition, antibodies that react with the FXN region have also been generated with this strategy. The HIV virus encoded a translational activator protein containing a 12 amino acid domain which permits transmembrane delivery of any therapeutic protein containing the sequence.

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.

Treatment for Wolfram Syndrome and Other Endoplasmic Reticulum Stress Disorders with Endoplasmic Reticulum Calcium Modulators

This technology includes the use of JTV-519 and oxidized form of JTV-519, as a novel treatment for Wolfram syndrome and other diseases associated with endoplasmic reticulum (ER). JTV-519 can prevent the leakage of ER calcium to the cytosol and abnormal activation of a pro-apoptotic enzyme, calpain 2, in cell models of Wolfram syndrome. Further, these compounds can prevent cell death in beta cell models of these diseases.

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.

Pyrazolo[1,5-a]pyrimidine Derivatives as Selective ALK Kinases Inhibitors for Inhibition of the Bone Morphogenetic Proteins Signaling Pathway for Treatment of Fibrodysplasia Ossificans Progressiva

This technology includes compounds which are selective inhibitors of anaplastic lymphoma kinases (ALK1, ALK2, ALK3 and ALK6), which inhibit these ALKs with low nanomolar potency. These compounds could be developed as a treatment of Fibrodysplasia ossificans progressiva (FOP) and other BMP-related diseases. FOP is a rare congenital disease with no current treatment options. Since the disease is driven by constitutively active ALK2, inhibition of ALK2 would be like hitting the Achilles’ heel of the disease and would potentially be an efficacious therapy for FOP patients.
