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.

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).

Kushenol K, a flavonoid antioxidant isolated from the roots of Sophora flavescens. Kushenol K is a cytochrome P-450 3A4 (CYP3A4) inhibitor with a Ki value of 1.35 μM. Kushenol K shows weak antiviral activity against HSV-2 (EC50 of 147 μM). Kushenol K also inhibits the activity of SGLT1 and SGLT2.

Uniconazole is a plant growth regulator that functions by inhibiting cytochrome P450 707As (Ki=68 nM), a family of enzymes that catabolize Abscisic acid, and thus, suppress gibberellin and sterol biosynthesis.

Resorufin methyl ether (Methoxyresorufin) is a cytochrome P450 fluorometric substrate. Resorufin methyl ether is a relatively specific substrate for CYP1A2 activity in rodents.

7-Ethoxyresorufin (Resorufin ethyl ether) is a fluorometric substrate and competitive inhibitor of cytochrome P450, especially CYP1A1. 7-Ethoxyresorufin also inhibits NO synthase.

β-Amyrenonol (11-Oxo-β-amyrin), an oleanolic-type triterpenoid in licorice roots, is a precursor of Glycyrrhetinic acid. β-Amyrenonol has anti-proliferative and anti-inflammatory activities, and β-Amyrenonol could function as the skeleton for the synthesis of many triterpenoids.
