Selisistat racemate is a racemic mixture of EX-527, an inhibitor of sirtuin 1 (SIRT1; IC50 = 0.098 µM).1 It is selective for SIRT1 over SIRT2, and SIRT3 (IC50s = 19.6 and 48.7 µM, respectively) and the cytochrome P450 (CYP) isoforms CYP3A4, CYP2D6, CYP2C9, CYP2C19, and CYP1A2 at 1 µM. EX-527 (50 µM) induces cell cycle arrest at the G1 phase in MCF-7 cells.
