Ketoconazole | Cytochrome P450 inhibitor

Ketoconazole (65277-42-1) is a broad spectrum antifungal agent which acts via inhibition of a cytochrome P450, CYP51A1 which is a lanosterol 14α-demethylase.1 Also inhibits CYP3A and CYP1A1.2 Inhibits adrenal steroidogenesis.3 Downregulates cholesterol synthesis in drug-tolerant human lung cancer cell lines.4 Blocks the biosynthesis of leukotrienes (LT) via inhibition of 5-lipoxygenase and dose dependently inhibits LT-mediated bronchoconstriction in guinea pigs.5
