them possessed good broad-spectrum inhibition activities, compared to Gefitinib. Especially, the IC50 values of compound 21 against HepG2, A549, MCF-7, DU145 and SH-SY5Y cells were 4.61, 9.50, 9.80, 6.79 and 7.77 μM, respectively, which were much lower than those of Gefitinb. Furthermore, the highlighting compound 21 demonstrated excellent inhibition activity against EGFR-TK with the IC50 value of 3.62 nM
基于4-苯胺基喹唑啉的衍生物代表了在药物化学领域中用于小分子EGFR-TKI的一种有吸引力的支架。已经设计,合成和评估了一系列新的杂环取代衍生物作为潜在的EGFR-TKIs的抗肿瘤生物活性。与吉非替尼相比,大多数新化合物对五种人类癌细胞的增殖具有一定的有效抑制潜能,其IC 50值在低微摩尔水平,并且其中一些具有良好的广谱抑制活性。特别是化合物21的IC 50值抗HepG2的A549,MCF-7,DU145和SH-SY5Y细胞分别为4.61、9.50、9.80、6.79和7.77μM,远低于吉非替尼。此外,突出化合物21表现出优异的针对EGFR-TK的抑制活性,IC 50值为3.62 nM,类似于吉非替尼(2.21 nM)。LDH释放测定的结果证明化合物21对HepG2细胞具有抗增殖作用而不是细胞毒性。化合物21能够引起HepG2细胞在S期阻断并主要通过线粒体依赖性途径的凋亡诱导细胞死亡。此外,MMP的评估,细胞内游离Ca
