Abstract

Two new mono-THF ring acetogenins, rollinecins A (1) and B (2), were isolated from the partitioned ethanolic extracts of the leaves of Rollinia mucosa (Annonaceae) by activity-directed fractionation. 1 and 2 are epimeric at the C-14 carbinol stereocenter. Their absolute stereochemical structures were solved by preparing their respective per-Mosher ester derivatives. 1 and 2 showed equivalent and selective in vitro activities against several human solid tumor cell lines.

摘要

通过活性导向分级分离,从番荔枝科植物圆滑番荔枝叶的乙醇提取物的分配物中分离出两种新的单四氢呋喃环番荔枝内酯,罗林菌素A(1)和B(2)。1和2在C-14甲醇立体中心处为差向异构体。通过制备它们各自的全莫舍尔酯衍生物确定了它们的绝对立体化学结构。1和2对几种人类实体瘤细胞系显示出同等且具有选择性的体外活性。
