Abstract

Monascin (1) constitutes one of the azaphilonoid Pigments in the extracts of Monascus pilosus-fermented rice (red-mold rice). Compound 1 was evaluated for its anti-tumor-initiating activity via oral administration on the two-stage carcinogenesis of mouse skin tumor induced by peroxynitrite (ONOO-; PN) or by ultraviolet LIGHT B (UVB) as an initiator and 12-O-tetradecanoylphorbol-13-acetate (TPA) as a promoter. Compound 1 exhibited marked inhibitory activity on both PN- and UVB-induced mouse skin carcinogenesis tests. These findings suggest that compound 1 may be valuable as potential Cancer chemopreventive agent in chemical and environmental carcinogenesis.
