Three new Securinega alkaloids, secu'amamines B-D ( 1- 3), were isolated from the wood of the Japanese medicinal plant Securinega suffruticosa var. amamiensis, together with five known analogues ( 4, 6- 9). The structures 1- 3 were elucidated by spectroscopic methods including 2D NMR, and all eight compounds were evaluated for cytotoxicity against two cancer cell lines.
从日本药用植物琉球叶底珠(Securinega suffruticosa var. amamiensis)的木材中分离出三种新的叶底珠生物碱,即叶底珠胺B-D(1-3),以及五种已知类似物(4、6-9)。通过包括二维核磁共振在内的光谱方法阐明了1-3的结构,并评估了所有八种化合物对两种癌细胞系的细胞毒性。
