TL;DR: A 24-epimeric mixture of a new triterpenoid, 24-hydroxydammara-20, 25-dien-3-one (1), and two known triterphenoids, moronic acid (2) and betulonic acid(3), were isolated from leaves of Chisosheton macrophyllus KING, and the inhibitory effects of these triterpoids on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13
Abstract: A 24-epimeric mixture of a new triterpenoid, 24-hydroxydammara-20, 25-dien-3-one (1), and two known triterpenoids, moronic acid (2) and betulonic acid (3), were isolated from leaves of Chisosheton macrophyllus KING, and the inhibitory effects of these triterpenoids on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate were tested.
