Notes: C527 is an inhibitor of USP1/UAF complex deubiquitinase activity (IC50 = 0.88 µM).{36957} It also inhibits USP5, UCL-H3, and USP12/46 but not UCL-H1 activity (IC50s = 1.65, 2.18, 5.97, and >10 µM, respectively). C527 increases ubiquinated Fanconi anemia complementation group D2 (FANCD2-Ub) and FANCI-Ub levels in a concentration-dependent manner. It inhibits homologous recombination repair, cell proliferation, and sensitizes HeLa cells to the DNA crosslinker mitomycin C (Item No. 11435). C527 also inhibits proliferation of PC3 and LNCap prostate cancer cells (IC50s = 0.24 and 0.03 µM, respectively, after 72 hours).{36958}
