anticancer agents. Numerous multikinase inhibitors (MKIs) have been recently approved for the treatment of cancer. Vascular endothelial growth factor receptor-2 (VEGFR-2) is the principal mediator of tumor angiogenesis. In an effort to develop ATP-competitive VEGFR-2 selective inhibitors the 5-chloro-N4-substituted phenyl-9H-pyrimido[4,5-b]indole-2,4-diamine scaffold was designed. The synthesis of the
抑制受体酪氨酸激酶 (RTK) 信号通路是开发新型抗癌药物的重要领域。许多多激酶抑制剂 (MKI) 最近已被批准用于治疗癌症。血管内皮生长因子受体-2 (VEGFR-2) 是肿瘤血管生成的主要介质。为了开发 ATP 竞争性 VEGFR-2 选择性抑制剂,设计了 5-氯-N 4 -取代的苯基-9 H-嘧啶并[4,5 - b ]吲哚-2,4-二胺支架。目标化合物的合成涉及N- (4,5-dichloro-9 H - pyrimido[4,5- b]indol-2-yl)-2,2-二甲基丙酰胺)作为常见的中间体。普通中间体的 4-氯基被适当取代的苯胺亲核置换,得到目标化合物。生物学评估表明,化合物5是一种有效的选择性 VEGFR-2 抑制剂,可与舒尼替尼和司马替尼相媲美。
