Inhibitors

Inhibitors	Comment	Organism	Structure
apigenin	competitive inhibition with the substrate 5alpha-dihydrotestosterone, uncompetitively inhibition with the cofactor NADPH. Significantly inhibits rat AKR1C9 at 0.1 mM; competitive inhibition with the substrate 5alpha-dihydrotestosterone, uncompetitively inhibition with the cofactor NADPH. Significantly inhibits rat AKR1C9 at 0.1 mM. Apigenin is a potent inhibitor of rat AKR1C9, thereby controlling the rate of neurosteroid biosynthesis	Rattus norvegicus
