series of acenaphtho[1,2-b]pyrrole derivatives as potent and selectiveinhibitors of fibroblastgrowthfactorreceptor1 (FGFR1) were designed and synthesized. In silico target prediction revealed that tyrosine kinases might be the potential targets of the representative compound 2, which was subsequently validated by enzyme-linked immunosorbent assay (ELISA) for its selective and active FGFR1 inhibition
设计并合成了一系列新颖的of [1,2- b ]吡咯衍生物,作为成纤维细胞生长因子受体1(FGFR1)的有效抑制剂和选择性抑制剂。在计算机靶标中预测,酪氨酸激酶可能是代表性化合物2的潜在靶标,随后通过酶联免疫吸附测定(ELISA)验证了其对多种酪氨酸激酶的选择性和活性FGFR1抑制作用。结构-活性关系(SAR)分析通过分子对接模拟在ATP结合位点辅助证明苊并[1,2- b ]吡咯羧酸酯(2 - 5)是具有IC FGFR1的有效抑制剂50值范围从19到77 nM。此外,这些化合物对表达FGFR的癌细胞系表现出有利的生长抑制特性,其IC 50值范围从微摩尔到亚微摩尔。Western印迹分析表明,化合物2,3,和图2b FGFR1的活化抑制和细胞外信号调节激酶1/2(ERK1 / 2)。
