(S)-Orteronel ((S)-Orteronel) 是人17，20-裂解酶 (17,20-lyase, CYP17) 选择性抑制剂(IC50:38 nM)，CYP17对(S)-Orteronel 选择性比对 11-hydroxylase 及 CYP3A4 高 1000 多倍。

fluorometric substrate of cytochrome P450

Cytochrome P450 metabolism of polyunsaturated fatty acids produces numerous bioactive epoxide regioisomers. (±)13(14)-EpDPA is a docosahexaenoic acid epoxygenase metabolite, derived via epoxidation of the 13,14-double bond of DHA. It has been detected in rat brain and spinal cord and is a preferred substrate for soluble epoxide hydrolase with a Km value of 3.2 μM. (±)13(14)-EpDPA demonstrates antihyperalgesic activity in inflammatory and neuropathic pain models. (±)13(14)-EpDPA and other epoxy metabolites of DHA are also reported to potently inhibit angiogenesis and tumor growth in in vitro assays.

6-Hydroxywarfarin 是(+)-华法林的代谢物，也一种较弱的维生素 K 拮抗剂。

Proadifen is a non-selective cytochrome P450 enzymes inhibitor, preventing some types of drug metabolism.

LKY-047, a derivative of Decursin, is a highly effective and specific reversible competitive inhibitor of cytochrome P45022J2 (CYP2J2), with an IC 50 value of 1.7 μM. LKY-047 does not display inhibitory activity against other human P450 enzymes including CYPs 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, and 3A.
