Compounds and Methods for Blocking Transmission of Malarial Parasites

Malaria continues to be a life-threatening disease, causing roughly 241 million cases and an estimated 627,000 deaths in 2020, mostly among African children, although in 2020 nearly half of the world’s population was at risk of malaria. There is a big financial burden for antimalarial treatment; direct costs (for example, illness, treatment, premature death) have been estimated to be at least US $12 billion per year and the cost in lost economic growth is many times more than that.

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.

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.

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.

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.

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.

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.

Zika Virus NS-1 Inhibitors for the Treatment of Zika Virus Infection

This technology includes a new Zika virus NS-1 assay which was used for a compound screen. Because the NS-1 protein is synthesized only in the Zika virus replication stage, the inhibition of NS-1 protein level by compounds determined in this NS-1 assay indicates the inhibition of Zika virus replication in human cells. A total of 256 compounds have been identified as active compounds that inhibited NS-1 production in human cells that have the potential to be developed as new therapeutics for the treatment of infection with Zika virus.

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.
