CYP450

Danshensu sodium salt (Sodium Danshensu) is sodium salt of danshensu from the widely used Chinese herb Danshen. It can inhibited phenylephrine- and CaCl2-induced vasoconstriction in Ca2+-free medium.

(E)-Flavokawain A, a novel chalcone from kava extract, induces apoptosis in bladder cancer cells by involvement of Bax protein-dependent and mitochondria-dependent apoptotic pathway and suppresses tumor growth in mice.

N-Acetyl-L-aspartic acid is a derivative of aspartic acid, synthesized in neurons from the amino acid aspartic acid and acetyl coenzyme A. N-Acetyl-L-aspartic acid has antioxidant activity.

Cyclosporin A is a naturally occurring cyclic polypeptide that is the active metabolite of a fungus. Cyclosporin A is an immunosuppressant that binds to procyclins and inhibits calcineurin (IC50=7 nM).

Naringin (Naringoside), a flavanone glycoside, exerts various of pharmacological effects such as blood lipid lowering, antioxidant activity, anticancer activity, and inhibition of cytochrome P450 enzymes.

Quinidine sulfate dihydrate (Pitayine Sodium) is a potent and selective cytochrome P450db inhibitor

Erucin （1-isothiocyanato-4-methylsulfanylbutane） is a dietary isothiocyanate produced by enzymatic hydrolysis of glucoErucin with potential cancer preventive effects, involved in apoptosis and cell cycle blockade through PARP-1 cleavage, p53 and p21，Cyp450, quinone reductase (QR), glutatione transferase (GST) and other pathways.

1. Humantenmine is a toxic compound isolated from Gelsemium elegans Benth . 2. Humantenmine and koumine may inhibit several CYP450 enzyme activities.

Curcumenol ((+)-Curcumenol), one of the major components of Zedoary turmeric oil, is an antibiotic drug which has anti-Y, anti-inflammation activity. Curcumenol may be safely used without inducing metabolic drug-drug interaction through P450 inhibition.

Polygalaxanthone III can significantly inhibit chlorzoxazone 6-hydroxylation catalyzed by CYP2E1.

Tetrahydropiperine (Cosmoperine) is a natural product derived from piperine, can be used to treat convulsion, epilepsy, relieve pain, and control insects.

1β-Hydroxydeoxycholic acid (1β-OH-DCA), recognized as a secondary bile acid, serves as a biomarker for CYP3A. This compound is metabolized from deoxycholic acid specifically by CYP3A4 and CYP3A7 through recombinant human CYP450 enzymes [1].
