A series of new 6-substituted-4-(3-bromophenylamino)quinazoline derivatives that may function as irreversible inhibitors of epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor (HER-2) tyrosine kinases have been prepared. These inhibitors have, at the C-6 position, butynamide, crotonamide, and methacrylamide Michael acceptors bearing water-solublilizing substituents. These
已经制备了一系列新的6-取代的4-(3-溴苯基氨基)喹唑啉衍生物,其可以用作表皮生长因子受体(EGFR)和人表皮生长因子受体(HER-2)酪氨酸激酶的不可逆抑制剂。这些抑制剂在C-6位具有带有水溶性增溶取代基的丁炔酰胺,巴豆酰胺和甲基丙烯酰胺迈克尔受体。这些化合物是通过将6-氨基-4-(3-溴苯基氨基)喹唑啉与不饱和酰氯或混合酸酐酰化而制备的。我们显示,由于迈克尔加成的分子内催化和/或质子化碱性基团的诱导作用,将碱性官能团附接到迈克尔受体上导致更大的反应性。加上改善的水溶性,产生具有增强的生物学特性的化合物。我们目前分子模型和实验证据,这些抑制剂与目标酶共价相互作用。一种化合物16a在裸鼠的人表皮样癌(A431)异种移植模型中显示具有出色的口服活性。
