Mechanism of Action

Targets/IC₅₀/Ki	CYP3A4 ^[1] 30 nM
In vitro	PF-4981517 (CYP3cide) is a potent, efficient, and specific time-dependent inactivator of human CYP3A4. This compound is tested as a reversible inhibitor of several human cytochrome P450 activities in pooled HLMs. It is selective for CYP3A4 with IC50 of 0.03 μM, 17 μM and 70 μM for CYP3A4, 3A5, and 3A7, respectively. This chemical is a mechanism-based inactivator. It serves as an important in vitro tool, which when used side-by-side with ketoconazole to inhibit all CYP3A activity will permit distinction between the contribution of CYP3A4 to CYP3A5 (as well as CYP3A7 and maybe CYP3A43). This compound is useful to investigators seeking to delineate the relative contribution of CYP3A4 versus CYP3A5 in the metabolism of compounds cleared by CYP3A. ^[1]
