  摘要：

  在发现4-[（3-溴苯基）氨基]-喹唑啉具有极高的抑制表皮生长因子受体（EGFR）酪氨酸激酶活性的能力（例如3，IC50为0.029 nM）之后，合成并评估了在6或7位带有供电子基团的相关吡啶并[d]嘧啶。通过亲核取代相应的6-和7-氟类似物来制备化合物。尽管所有系列成员均显示出对分离的EGFR的有效抑制活性，但不同的异构吡啶并[d]嘧啶与母体喹唑啉之间存在重要差异。总的来说，[3,4-d]和[4,3-d]系列是最有效的，其次是[3,2-d]化合物，[2,3-d]类似物的活性最低。在母体喹唑啉系列中，向6-或7-NH2取代基（即NHMe和NMe2基团）中增加空间位阻会显着降低效能，而在[3,2-d]系列中则没有这种趋势。此外，在7-取代的吡啶并[4,3-d]-和6-取代的吡啶并[3,4-d]嘧啶系列中，并且在有限的程度上在7-取代的吡啶并[2,3-d]系列中，这样的取代作用显着提高了效力，其程度为7-（甲基氨基）吡啶并[4
