Chemoprevention studies of heterocyclic amine-induced colon carcinogenesis.

abstract：:As a continuation of studies using natural and synthetic products as cancer chemopreventive agents, we examined the reduction-oxidation potentials of hydroxylated emodin derivatives prepared from emodin in phosphate buffer at pH 7.2 using cyclic voltammetry. A significant correlation was found between the reduction po...
