Abstract

Hispidacine, an 8,4'-oxyneolignan featuring incorporation of an unusual 2-hydroxyethylamine moiety at C-7, and hispiloscine, a phenanthroindolizidine alkaloid, were isolated from the stem-bark and leaves of the Malaysian Ficus hispida Linn. Their structures were established by spectroscopic analysis. Hispidacine induced a moderate vasorelaxant activity in rat isolated aorta, while hispiloscine showed appreciable antiproliferative activities against MDA-MB-231, MCF-7, A549, HCT-116 and MRC-5 cell lines.

摘要

从马来西亚榕属植物毛果榕的茎皮和叶子中分离出了毛果辛(一种8,4'-氧化新木脂素,其在C-7位含有一个不寻常的2-羟乙胺部分)和毛果洛辛(一种菲并吲哚里西啶生物碱)。它们的结构通过光谱分析得以确定。毛果辛在大鼠离体主动脉中诱导出适度的血管舒张活性,而毛果洛辛对MDA-MB-231、MCF-7、A549、HCT-116和MRC-5细胞系显示出明显的抗增殖活性。
