Four quinolone-terpene alkaloids, chelerybulgarine (1), 2'-episimulanoquinoline (3), 2,11-didemethoxyvepridimerine B (4), and rhetsidimerine (5) were isolated from the root bark of Zanthoxylum rhetsa DC. Chelerybulgarine (1) is a C-C linked terpene alkaloid where the C-6 of dihydrochelerythrine is linked to C-11 of the sesquiterpenoid 10β-methoxybulgarene. 2'-Episimulanoquinoline is a dimeric alkaloid containing dihydrochelerythrine and 8-methoxy-N-methylflindersine moieties, whereas 2,11-didemethoxyvepridimerine B and rhetsidimerine are dimeric prenylated quinolone alkaloids. Seven of the isolated compounds exhibited weak cytotoxicity when tested against a panel of six human stomach-cancer cell lines.
从刺花椒(Zanthoxylum rhetsa DC.)的根皮中分离出四种喹诺酮-萜类生物碱,即白屈菜红碱(1)、2'-表异西番莲喹啉(3)、2,11-二去甲氧基维普地米林B(4)和刺花椒二聚碱(5)。白屈菜红碱(1)是一种碳-碳连接的萜类生物碱,其中二氢白屈菜红碱的C-6与倍半萜10β-甲氧基保加烯的C-11相连。2'-表异西番莲喹啉是一种含有二氢白屈菜红碱和8-甲氧基-N-甲基弗林德辛部分的二聚生物碱,而2,11-二去甲氧基维普地米林B和刺花椒二聚碱是二聚的异戊烯基喹诺酮生物碱。在对六种人胃癌细胞系进行测试时,七种分离出的化合物表现出较弱的细胞毒性。
