In Vitro Bendazac is an anti-inflammatory agent endowed with protein antidenaturant properties effective for various inflammatory skin conditions. Bendazac has been shown to be a strong reacting substrate in a chemical oxidizing system, which mimics a physiological pathway of hydroxy radical generation[2]. By using EPR spectroscopy of spin-labelled bovine serum albumin (BSA), Bendazac was shown to prevent the BSA denaturation induced by urea, heat and free radicals produced in the xanthine/xanthine oxidase system[2].
