PF-4981517

Description: PF-4981517 (CYP3cide) is a efficient, specific and time-dependent inhibitor of cytochrome P4503A4 (CYP3A4). The IC 50 values for CYP3A activity are 0.03 µM,17 µM, and 71 µM for CYP3A4, CYP3A5, and CYP3A7, respectively. PF-4981517 is able to be used to distinguish the contributions of CYP3A4 versus CYP3A5 on drug Metabolism. Target: P450. Smiles: Cc1ccc(cc1)-c1c(cnn1C)-c1nn(C)c2ncnc(N3CC[C@@H](C3)N3CCCCC3)c12.
