Following the discovery of the very high inhibitory ability of the 4-[(3-bromophenyl)amino]-quinazolines against the tyrosine kinase activity of the epidermal growth factor receptor (EGFR) (e.g., 3, IC50 0.029 nM), four series of related pyrido[d]pyrimidines bearing electron-donating groups at the 6- or 7-positions have been synthesized and evaluated. The compounds were prepared by nucleophilic substitution
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
