pharmacophore model for ATP-competitive inhibitors interacting with the active site of the EGFR protein tyrosine kinase and a putative binding mode of 4-anilinoquinazoline suggest that a salicylic acid function could serve as the pharmacophore replacement of a pyrimidine ring. Superpositions by CAMM of salicylanilides with the potent EGFR tyrosine kinase inhibitor 4-[(3'-chlorophenyl)amino]-6,7-dimethoxyquinazoline
ATP竞争性抑制剂与EGFR蛋白酪氨酸激酶活性位点相互作用的药效团模型和推定的4-苯胺基喹唑啉结合模式表明,水杨酸功能可以用作嘧啶环的药效团替代。CAMM将水杨酰苯胺与有效的EGFR酪氨酸激酶抑制剂4-[(3'-氯苯基)氨基] -6,7-二甲氧基喹唑啉叠加显示水杨酰苯胺应作为酪氨酸激酶抑制剂。合成了一系列水杨酰苯胺,并确定了它们对酪氨酸激酶的抑制活性。实际上,其中一些确实被证明是有效的选择性EGFR酪氨酸激酶抑制剂。最有效的是28、16、20、6和15,IC(50)在23-71 nM范围内。
