A series of substituted 4-(2,4-difluoro-5-(methoxycarbamoyl)phenylamino)pyrrolo[2,1-f][1,2,4]triazines was identified as potent and selective inhibitors of the tyrosine kinase activity of the growth factor receptors VEGFR-2 (Flk-1, KDR) and FGFR-1. The enzyme kinetics associated with the VEGFR-2 inhibition of compound 50 (K(i) = 52 +/- 3 nM) confirmed that the pyrrolo[2,1-f][1,2,4]triazine analogues
一系列取代的4-(2,4-二氟-5-(甲氧基氨基甲酰基)苯基氨基)吡咯并[2,1-f] [1,2,4]三嗪被确定为有效的和选择性的酪氨酸激酶活性抑制剂。生长因子受体VEGFR-2(Flk-1,KDR)和FGFR-1。与VEGFR-2抑制化合物50有关的酶动力学(K(i)= 52 +/- 3 nM)证实吡咯并[2,1-f] [1,2,4]三嗪类似物与ATP具有竞争性。几种类似物表现出对VEGF和FGF依赖的人脐静脉内皮细胞(HUVEC)增殖的低纳摩尔抑制作用。吡咯并[2,1-f] [1,2,4]三嗪核心的C6酯取代基被杂环生物等排体取代,例如取代的1,3,5-恶二唑,所提供的化合物在小鼠中具有优异的口服生物利用度(即50 F(po)= 79%)。用化合物44、49和50对植入无胸腺小鼠中的已建立的L2987人肺癌异种移植物观察到显着的抗肿瘤功效。介绍了该系列中类似物的合成,构效关系,药理学和药代动力学特性的完整说明。
