TH-407a is a potent and selective, reversible, non-competitive inhibitor of ubiquitin-specific peptidase 15 (USP15) with IC50 of 0.76 uM.
TH-407a inhibits the hydrolysis of Ub-AMC by USP15 in vitro, also inhibits the binding of USP15 to Ub-PA.
TH-407a exhibits negligible inhibition of USP1, USP2, and USP7 at 10 uM.
TH-407a inhibits USP15 via an allosteric regulatory mechanism rather than direct competition with the catalytic site.
TH-407a inhibits breast cancer cell proliferation with IC50 of 19.57 uM and 38.66 uM for MCF-7 and MDA-MB-436 cells, inhibits colony formation, and cancer cell migration.
TH-407a activates the p53 signaling pathway and inhibits the expression of PARP1.
TH-407a (100 mg/kg, oral gavage daily) significantly reduces tumor growth in mice xenografts with MCF-7 and MDA-MB-436 cells.
