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...

PF-04981517 is a potent, time-dependent inhibitor of the cytochrome P450 (CYP450) isoform CYP3A4 (IC50 = 30 nM). It is less effective against CYP3A5 and CYP3A7 (IC50s = 17 and 70 µM, respectively). PF-04981517 will be useful for understanding the relative roles of CYP3A4 and CYP3A5 in drug metabolism.Formal Name:...
