N-苯基-N '-[4-(5 H-吡咯并[3,2 - d ]嘧啶-4-基氧基)苯基]脲作为VEGFR和FGFR激酶的新型抑制剂
摘要:
我们最近报道了吡咯并[3,2- d ]嘧啶衍生物1a和1b作为血管内皮生长因子受体(VEGFR),血小板衍生生长因子受体(PDGFR)和Tie-2激酶的有效三重抑制剂的发现。为了鉴定对成纤维细胞生长因子受体(FGFR)激酶具有强抑制活性的化合物,使用VEGFR2和1b的共晶体结构分析进行了进一步修饰。在合成的化合物中,在末端苯环上具有哌嗪部分的尿素衍生物11l显示出对FGFR1激酶和VEGFR2激酶的强抑制活性。11l的绑定模型 与VEGFR2复合表明哌嗪部分与Ile1025和His1026形成额外的相互作用。
