Kushenol M is a flavonoid from Sophora flavescens. Kushenol M is a cytochrome P450 (CYP), with IC50 values of 1.29 μM for CYP3A4 in in human liver microsomes.

1-Aminobenzotriazole (ABT, 3-Aminobenzotriazole, 1-Benzotriazolylamine, NSC 114498, NSC 656987) is a nonselective and irreversible inhibitor of cytochrome P450 (CYP) enzymes. 1-Aminobenzotriazole is also a substrate and inhibitor of N-acetyltransferase (NAT).

Quinidine sulfate dihydrate is a potent and selective inhibitor of cytochrome P450db and inhibits amphetamine metabolism in vivo. Quinidine sulfate dihydrate enhances the cytotoxicity of vincristine (VCR) in tumor cells and especially in VCR-resistant sublines of P388 leukemia (P388/VCR) and human myelogenous leukemia.

CYP11B2-IN-1 is a CYP11B2 inhibitor with an IC50 of 2.3 nM. CYP11B2-IN-1 inhibits CYP11B1 with an IC50 of 142 nM.

Methoxsalen (Oxsoralen)

HET0016 (HET-0016) is a potent, selective inhibitor of CYP4A, potently inhibits the formation of 20-HETE with IC50 of 8.9 nM in human renal microsomes.

DMU2105 is a potent and specific CYP1B1 inhibitor, with IC50s of 10, 742 nM for CYP1B1 and CYP1A1, respectively.

CDD3506 is used for elevating high density lipoprotein cholesterol (HDL) by inducing hepatic cytochrome P450IIIA (CYP3A) activity.

CDD3505 is used for elevating high density lipoprotein cholesterol (HDL) by inducing hepatic cytochrome P450IIIA (CYP3A) activity.

Carbosulfan inhibited relatively potently CYP3A4 and moderately CYP1A1/2 and CYP2C19 in pooled HLM (human livers). Carbosulfan activation is predominantly catalyzed in humans by CYP3A4.

Abiraterone (CB-7598) is a potent CYP17 inhibitor with IC50 of 2 nM.
