摘要
To search for cancer chemopreventive agents from natural sources, 13alpha,14alpha-epoxy-21alpha-methoxyserratan-3one, 21alpha-methoxyserrat-13-en-3-one, and 21alpha-hydroxy-3beta-methoxyserrat-14-en-30-al isolated from the cuticle of Picea jezoensis (SIEB. et Zucc.) CARR. var jezoensis (Pinaceae) were investigated for inhibitory effects in a two-stage mouse skin carcinogenesis test on mouse skin with 7,12-dimethylbenz[a]anthracene (DMBA) as initiator and 12-O-tetradecanoylphorbol-13-acetate (TPA) as promoter. 21alpha-hydroxy-3beta-methoxyserrat-14-en-30-al and 13a,14a-epoxy-2la-methoxyserratan-3-one were found to exhibit strong antitumor-promoting activities in the in vivo carcinogenesis test.
