- Development of Benzenesulfonamide Derivatives as Potent Glutathione Transferase Omega-1 Inhibitors
-
Glutathione transferase omega-1 (GSTO1-1) is an enzyme whose function supports the activation of interleukin (IL)-1β and IL-18 that are implicated in a variety of inflammatory disease states for which small-molecule inhibitors are sought. The potent reactivity of the active-site cysteine has resulted in reported inhibitors that act by covalent labeling. In this study, structure-activity relationship (SAR) elaboration of the reported GSTO1-1 inhibitor C1-27 was undertaken. Compounds were evaluated for inhibitory activity toward purified recombinant GSTO1-1 and for indicators of target engagement in cell-based assays. As covalent inhibitors, the kinact/KI values of selected compounds were determined, as well as in vivo pharmacokinetics analysis. Cocrystal structures of key novel compounds in complex with GSTO1-1 were also solved. This study represents the first application of a biochemical assay for GSTO1-1 to determine kinact/KI values for tested inhibitors and the most extensive set of cell-based data for a GSTO1-1 inhibitor SAR series reported to date. Our research culminated in the discovery of 25, which we propose as the preferred biochemical tool to interrogate cellular responses to GSTO1-1 inhibition.

- METHODS AND COMPOUNDS FOR TREATING PROLIFERATIVE DISORDERS AND VIRAL INFECTIONS
-
The invention generally relates to methods and compounds for treating proliferative disorders, viral infections, or both. In some embodiments, the invention provides an anticancer or antiviral compound including a substituted nitro phenoxy phenyl, a sulfonylurea, and an alkyl group. In some embodiments, the invention provides a method of treating a proliferative disorder or a viral infection including administering an anticancer or antiviral compound that binds to a thromboxane receptor, has preferential binding for either TPalpha (TPα) or TPbeta (TPβ) receptor subtype.

- Synthesis and evaluation of novel monosubstituted sulfonylurea derivatives as antituberculosis agents
-
A series of novel monosubstituted sulfonylurea derivatives 10a-y were synthesized and characterized by 1H NMR, 13C NMR and HRMS. These compounds were evaluated against Mycobacterium tuberculosis H37Rv in vitro. The results showed compounds 10f, 10k and 10s exhibited moderate antituberculosis activities with MIC values in the range of 20-100 mg/L. Compounds 10b and 10o displayed good antituberculosis activities (MIC 10 mg/L), which were comparable with that of the sulfometuron methyl. Both of the two compounds showed little cytotoxicities, with an IC50 against THP-1 cells greater than 100 mg/L.
