Abstract
Four new bisindole alkaloids, cathagines A (1)-D (4) consisting of an aspidosperma and the fused tetracyclic 3-spirooxindole derived from an iboga type skeleton were isolated from the whole plant of Catharanthus roseus. The structures including absolute stereochemistry were elucidated on the basis of 2D NMR data and CD spectra. Cathagine B (2) showed moderate anti-malarial activity against Plasmodium falciparum 3D7.
从长春花全株中分离出了四种新的双吲哚生物碱，即由一种表吲哚和融合的四环 3-螺氧吲哚组成的长春花碱 A (1)-D (4)，它们都来自一种伊勃加类型的骨架。根据二维核磁共振数据和 CD 光谱阐明了它们的结构，包括绝对立体化学结构。Cathagine B (2) 对恶性疟原虫 3D7 具有中等抗疟活性。
