analysis for these compounds and their relative potency and selectivity to inhibit particular RTKs has determined that (1) 3-[(five-membered heteroaryl ring)methylidenyl]indolin-2-ones are highly specific against the VEGF (Flk-1) RTK activity, (2) 3-(substituted benzylidenyl)indolin-2-ones containing bulky group(s) in the phenyl ring at the C-3 position of indolin-2-ones showed high selectivity toward
已经设计并合成了3-取代的吲哚-2-酮,作为一类新型的酪氨酸激酶抑制剂,该抑制剂对不同的受体酪氨酸激酶(RTK)具有选择性。已经评估了这些化合物对完整细胞中一组RTK的相对抑制特性。通过修饰3-取代的吲哚-2-酮,我们鉴定了在亚微摩尔水平下显示选择性抑制各种RTK的配体依赖性自磷酸化的化合物。这些化合物的结构活性分析及其抑制特定RTK的相对效能和选择性已确定(1)3-[((五元杂芳基环)亚甲基]茚满-2-酮对VEGF(Flk-1 )RTK活动,(2)在吲哚-2-酮的C-3位的C-3位置的苯环中含有庞大基团的3-(取代的苄基)吲哚啉-2-酮显示出对EGF和Her-2 RTK的高选择性,并且( 3)在针对PDGF和VEGF(Flk-1)RTK进行测试时,在吲哚-2-酮(16)的C-3位置包含延伸的侧链的化合物表现出较高的效价和选择性。这些3-取代的吲哚-2-酮中的两个的最近公布的晶体学数据提供
