A novel type of cinnamic acid quinazoline amide derivatives (20–42), which designed the combination between quinazoline as the backbone and various substituted cinnamic acid as the side chain, have been synthesized and their biological activities were evaluated within cytotoxicity assay firstly and then potent EGFR inhibitory activity. Compound 42 demonstrated the most potent inhibitory activity (IC50 = 0
一种新的类型的肉桂酸喹唑啉酰胺衍生物(的20 - 42),其设计喹唑啉作为骨架和各种取代的肉桂酸作为侧链之间的组合,已被合成和它们的生物活性进行了细胞毒性测定法中评价首先,然后有力EGFR抑制活性。化合物42表现出最强的抑制活性( EGFR的IC 50 = 0.94μM),可以在进一步的研究中将其优化为潜在的EGFR抑制剂。进行对接模拟以将化合物42定位在EGFR活性位点中以确定可能的结合模型。42的结合构象分析在活性位点显示,化合物42通过与Lys822的氢键相互作用而稳定,这与其他衍生物不同。在进一步的研究中,合成了化合物43和44,并评估了其生物学活性,与我们预期的相同。化合物43 作为潜在的抗癌剂已显示出显着的EGFR(IC 50 = 0.12μM)和抑制肿瘤生长的活性。
