A series of 4-substituted quinazolines and related compounds have been prepared and evaluated for their ability to inhibit the tyrosine kinase activity of the epidermal growth factor receptor on a phospholipase C-gamma 1-derived substrate. The results show a narrow structure-activity relationship (SAR) for the basic ring system, with quinazoline being the preferred chromophore and benzylamino and anilino
已经制备了一系列的4-取代的喹唑啉和相关化合物,并评估了它们在磷脂酶C-γ1衍生的底物上抑制表皮生长因子受体的酪氨酸激酶活性的能力。结果表明基本环系统的结构-活性关系(SAR)狭窄,喹唑啉是优选的生色团,苄基氨基和苯胺基是优选的侧链。在4-苯胺基系列中,苯环的3-位被小的亲脂性吸电子基团取代提供了具有增强效价的类似物。研究了两个系列的化合物[4-(苯甲基)氨基和4-(3-溴苯基)氨基],以确定喹唑啉取代基的SAR。在更具活性的4-(3-溴苯基)氨基系列中,给电子基团(NH2,OMe)在6或7位的活性增加,其模式与对喹唑啉环的8位附近的高电子密度的要求一致。6,7-二甲氧基衍生物是这两个系列中最有效的,而4-(3-溴苯基)氨基衍生物(3)的IC50为0.029 nM,是迄今为止最有效的酪氨酸激酶活性抑制剂。表皮生长因子受体酶的作用。
