Abiesenonic acid methyl ester (AVB-I acid methyl ester), a triterpenoid compound prepared from abieslactone, suppressed tumor promoter-induced phenomena in vitro and in vivo; i.e., AVB-I acid methyl ester inhibited 12-o-tetradecanoylphorbol-13-acetate (TPA)-stimulated 32Pi-incorporation into
Abieslactone is a triterpenoid lactone isolated from Abies plants. Previous studies have demonstrated that its derivative abiesenonic acid methyl ester possesses anti-tumor-promoting activity in vitro and in vivo. In the present study, cell viability assay demonstrated that abieslactone had
Triterpenoid compounds, isolated from plants of Abies genus (Pinceae), are known to exert anti-tumor promotion activities in mouse skin carcinogenesis. In the present study, we investigated whether AVB-1 and acid and acid methyl ester derivatives have inhibitory effects on rat hepatocarcinogenesis
During the course of a search for biologically active constituents from unexamined plant sources, several biogenetically interesting new di- and tri-terpenes and steroids were isolated from several weeds and shrubs of Euphorbiaceae and the bark, leaves and cones of several Pinaceae trees which had
