Metyrapone
Tocris Bioscience, part of Bio-Techne | Catalog # 3292
11-β hydroxylase inhibitor
Product Description
Metyrapone is a cytochrome P450 inhibitor. Blocks glucocorticoid synthesis via inhibition of steroid 11-β hydroxylase (CYP11B1) activity (IC50 = 7.83 μM). Also inhibits CYP3A4 and cytochrome P450-mediated ω/ω-1 hydroxylase activity.Product Specifications
