designed as EGFR and VEGFR-2 dual inhibitors were synthesized and evaluated for inhibitory effects. EGFR and VEGFR-2 are validated targets in cancer therapy and combined inhibition might be synergistic for both antitumor activity and resistance prevention. The biological data obtained proved the potential of 2-chloro-4-anilino-quinazoline derivatives as EGFR and VEGFR-2 dual inhibitors, highlighting
合成了设计为EGFR和VEGFR-2双重抑制剂的新型2-氯-4-苯胺基喹唑啉并评估了其抑制作用。EGFR和VEGFR-2在癌症治疗中是经过验证的靶标,联合抑制可能在抗肿瘤活性和耐药性预防方面具有协同作用。获得的生物学数据证明了2-氯-4-苯胺基喹唑啉衍生物作为EGFR和VEGFR-2双重抑制剂的潜力,突出了化合物8o,其对VEGFR-2的效力大约高7倍,而效力则高11倍。在EGFR上与原型相比7。SAR和对接研究允许鉴定两种激酶的药效基团,并证明了氢键供体在对位的重要性苯胺部分与EGFR和VEGFR-2结合位点中保守的Glu和Asp氨基酸相互作用的位置。
