of 7-pyrrolo[3,2-f]quinolinones was obtained by introducing benzoyl, sulfonyl and carbamoyl side chains at the 3-N position, and their cytotoxicity against a panel of leukemic and solid tumor cell lines was evaluated. Most of them showed high antiproliferative activity with GI50s ranging from micro-to sub-nanomolar values, and these values correlated well with the inhibitory activities of the compounds
通过在3-N位置引入苯甲酰基,磺酰基和氨基甲酰基侧链获得7-吡咯并[3,2-f]喹啉酮的小文库,并评估其对一组白血病和实体瘤细胞系的细胞毒性。它们中的大多数显示出高的抗增殖活性,GI50的范围从微纳摩尔到亚纳摩尔值,这些值与化合物对微管蛋白聚合的抑制活性非常相关。基于最近提出的秋水仙碱结合位点抑制剂(CBSI)药效团,在秋水仙碱域中新型7-PPyQ的相互作用被合理化。活性最高的化合物(4a和4b)在正常人淋巴细胞中不会诱导明显的细胞死亡,这表明这些化合物可能对癌细胞具有选择性。特别是,4a是HeLa和Jurkat细胞系中凋亡的有效诱导剂。另一方面,与4a相比,磺酰基衍生物4b显示出较低的效力。对于这两种化合物,细胞凋亡的诱导与线粒体跨膜电位的耗散和活性氧的产生有关,这表明用这些化合物处理的细胞遵循细胞凋亡的内在途径。
