Ketoconazole is an imidazole-containing small molecule inhibitor of cytochrome P-450-dependent steps in the biosynthesis of steroid hormones; also inhibits TXA Synthase (thromboxane synthetase) and 5-LO (5-lipoxygenase) activity. Ketoconazole exhibits antimetastatic, antineoplastic, and antipsoriatic activity. Inhibition of 5-LO (5-lipoxygenase) by Ketoconazole interrupts arachidonic acid (sc-200770)-derived leukotriene production, which was correlated to a suppression of leukotriene-mediated anaphylactic bronchoconstriction in guinea pigs. Ketoconazole is described as reducing platelet cellular levels of thromboxane A2, suppressing thromboxane A2-mediated increase of microvascular permeability in response to ischemia insults. Ketoconazole produces an antiandrogen effect through inhibition of adrenocorticoid biosynthesis, suppressing the adrenal secretion of androgens and attenuating cortisol response. Ketoconazole is an inhibitor of CYP17A1, CYP3A4 and CYP3A5.
