从云南丽江产的玛氏独行菜(Lepidium meyeniic)根中分离得到3个新的吡咯生物碱macapyrrolinsA-C(1-3)。其结构经核磁共振和质谱鉴定。有趣的是,macapyrrolins A-C代表了在Lepidium meyenii中发现的吡咯生物碱的第一个例子,其中苄基取代基连接到吡咯核上。评价所有分离的macapyrrolin对5种人癌细胞系的细胞毒性。然而,在高达40 μM的浓度下未检测到显著活性。
Three new pyrrole alkaloids macapyrrolins A–C (1–3) were isolated from the roots ofLepidium meyeniicollected from Lijiang, Yunnan province in China. Their structures were elucidated by extensive NMR and MS spectroscopic analyses. Interestingly, macapyrrolins A–C represent the first examples of pyrrole alkaloids found inLepidium meyeniiwith a benzyl substituent attached to the pyrrole nucleus. All the isolated macapyrrolins were evaluated for their cytotoxicity against five human cancer cell lines. However, no significant activities were detected at concentrations up to 40 μM.
