该产品在溶液状态不稳定，建议您现用现配，即刻使用。 A cell-permeable bis-nitrobenzylidene-piperidinone that inhibits 19S deubiquitinase (DUB) activity (IC50 = 2.1 µM against Ub-AMC hydrolysis) in a reversible manner by directly targeting UCH37/UCH-L5 and USP14, while exhibiting little or no activity toward BAP1, UCH-L1, UCH-L3, USP2, USP7, USP8 (IC50 >100 µM), or POH1/PRN11. Dual UCH37 and USP14 inhibition by a-AP15 results in increased bulk cellular protein ubiquitination level and a blockage of protein proteasomal degradation (Effective conc. ≥770 nM in HCT-116 cells), exactly opposite to the effects seen with USP14 inhibition alone by IU1 (Cat. No. 662210). Effectively suppresses the growth of various tumors in mice (2.5 to 5 mg/kg, i.p. or s.c.) in vivo.
