With the goal of developing multitargeted receptor tyrosine kinase inhibitors that display potent inhibition against PDGFRβ and VEGFR-2 we designed and synthesized eleven N4-(3-bromophenyl)-7-(substitutedbenzyl) pyrrolo[2,3-d]pyrimidines 9a–19a. These compounds were obtained from the key intermediate N4-(3-bromophenyl)-7H-pyrrolo[2,3-d]pyrimidine-2,4-diamine 29. Various arylmethyl groups were regiospecifically
为了开发对 PDGFR β和 VEGFR-2 具有有效抑制作用的多靶点受体酪氨酸激酶抑制剂,我们设计并合成了 11 种N 4 -(3-溴苯基)-7-(取代苄基)吡咯并[2,3- d ]嘧啶9a – 19a . 这些化合物是从关键中间体N 4 -(3-溴苯基)-7 H-吡咯并[2,3- d ]嘧啶-2,4-二胺29获得的。通过氢化钠诱导的取代芳基甲基卤化物的烷基化,将各种芳基甲基基团区域特异性连接在29的N7处。化合物11a和19a是PDGFRβ和VEGFR-2的有效双重抑制剂。在 COLO-205 中,体内肿瘤小鼠模型11a表现出对肿瘤生长、转移和肿瘤血管生成的抑制作用,优于或相当于标准化合物 TSU-68 (SU6668, 8 )。
