EGFR and VEGFR-2 are involved in pathological disorders and the progression of different kinds of tumors, the combined blockade of EGFR and VEGFR signaling pathways appears to be an attractive approach to cancer therapy. In this work, a series of 4-anilinoquinazoline derivatives containing substituted diaryl urea or glycine methyl ester moiety were designed and identified as EGFR and VEGFR-2 dual inhibitors
EGFR和VEGFR-2参与病理性疾病和不同类型肿瘤的进展,EGFR和VEGFR信号通路的联合阻断似乎是一种有吸引力的癌症治疗方法。在这项工作中,设计了一系列含有取代的二芳基尿素或甘氨酸甲酯部分的4-苯胺基喹唑啉衍生物,并将其鉴定为EGFR和VEGFR-2双重抑制剂。化合物19i,19j和19l对EGFR表现出最强的抑制活性(分别为IC 50 = 1 nM,78 nM和51 nM)和VEGFR-2(分别为IC 50 = 79 nM,14 nM和14 nM)。表现出良好的抗增殖活性。分子对接建立了具有VEGFR-2的DFG-out构象的19i,表明它们可能是II型激酶抑制剂。
