A novel series of trifluoromethyl-containing quinazoline derivatives with a variety of functional groups was designed, synthesized, and tested for their antitumor activity by following a pharmacophore hybridization strategy. Most of the 20 compounds displayed moderate to excellent antiproliferative activity against five different cell lines (PC3, LNCaP, K562, HeLa, and A549). After three rounds of
通过遵循药效团杂交策略,设计、合成了一系列具有多种官能团的新型含三氟甲基喹唑啉衍生物,并测试了其抗肿瘤活性。 20 种化合物中的大多数对五种不同的细胞系(PC3、LNCaP、K562、HeLa 和 A549)表现出中等至优异的抗增殖活性。经过三轮筛选和结构优化,化合物10b被确定为最有效的化合物,对PC3、LNCaP和K562细胞的IC 50值分别为3.02、3.45和3.98μM,与阳性对照吉非替尼。为了进一步探讨10b抗癌作用机制,进行了侧重于细胞凋亡诱导、细胞周期阻滞和细胞迁移测定的实验。结果显示10b能够诱导细胞凋亡并阻止肿瘤细胞迁移,但对肿瘤细胞的细胞周期没有影响。
