    Product Description

    Benzbromarone is an inhibitor of the urate anion transporter (IC50 = 0.3 µM for hURAT1) that prevents renal urate resorption.1 It also potently inhibits CYP2C9 (Ki = 20 nM), a major cytochrome P450 enzyme involved in the metabolic clearance of a wide range of therapeutic agents.2 Several analogs of benzabromarone have been developed with varying binding affinities to CYP2C9 in order to study adverse drug-drug interactions.3

    WARNING This product is not for human or veterinary use.
