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.

| In vitro | When investigating the inhibition of PF-4981517, an extreme metabolic inactivation efficiency (k inact /K I ) of 3300 to 3800 ml min -1 μmol -1 is observed in human liver microsomes from donors of nonfunctioning CYP3A5 (CYP3A5 * 3/ * 3). This observed efficiency equated to an apparent KI between 420 and 480 nM with a maximal inactivation rate (kinact) equal to 1.6 min -1. When PF-4981517 is tested at a concentration and preincubation time to completely inhibit CYP3A4 in a library of genotyped polymorphic CYP3A5 microsomes, the correlation of the remaining CYP3A activity to CYP3A5 abundance is significant. |
