of thia analogues of protoberberine alkaloids, 13-carboxy-13,13a-dihydro-6H,8H-isoquinolino [2,3-c][1,3]benzothiazin-8-ones, with thionyl chloride, followed by ethanol, unexpectedly provided 5,11-dioxoindeno [1,2-c]isoquinoline derivatives containing a novel ring system. Elucidation of their structures is presented in this paper. The antiproliferative effects of thiaprotoberberines and indenoisoquinolines
用硫酰氯,然后用乙醇,意外地处理原小ber碱生物碱,13-羧基-13,13a-二氢-6H,8H-异喹啉[2,3-c] [1,3]苯并噻嗪-8-的硫杂类似物提供了含有新型环系统的5,11-二氧代茚并[1,2-c]异喹啉衍生物。本文介绍了它们的结构。通过MTT测定针对一组人类贴壁癌细胞系(Hela,MCF7和A431)确定了噻菌灵小ber碱和茚并异喹啉的抗增殖作用。
