Inhibitory effects of semisynthetic flavonoid derivatives on the biochemical markers of tumor promotion in mouse epidermis in vivo.


Two sets of flavonoid derivatives were synthesized from condensed tannins (CTs) or catechin, and compared with the procyanidin monomer models, (+)-catechin and (-)-epicatechin, for their abilities to inhibit the biochemical effects of the potent tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate (TPA) in mouse epidermis in vivo. Topical applications of… (More)
