Eight series of quinazoline derivatives bearing 2,3-dihydro-indole or 1,2,3,4-tetrahydroquinoline were designed, synthesized and evaluated for the IC50 values against three cancer cell lines (A549, MCF-7 and PC-3). Most of the forty nine target compounds showed excellent antiproliferative activity against one or several cancer cell lines. The compound 13a showed the best activity against A549, MCF-7
设计,合成并评估了八种带有2,3-二氢吲哚或1,2,3,4-四氢喹啉的喹唑啉衍生物对三种癌细胞系(A549,MCF-7和PC-3)的IC 50值。四十九种目标化合物中的大多数对一种或几种癌细胞系均表现出优异的抗增殖活性。化合物13a对A549,MCF-7和PC-3癌细胞系表现出最佳活性,其IC 50为50值分别为1.09±0.04μM,1.34±0.13μM和1.23±0.09μM。进一步选择了八种选择的化合物以评估其对EGFR激酶的抑制活性。其中三个显示出与阳性对照afatinib相同的针对EGFR激酶的活性。AnnexinV-FITC,碘化丙啶(PI)双重染色和a啶橙单次染色结果表明,化合物13a可以诱导人肺癌A549细胞凋亡。
