series of acenaphtho[1,2-b]pyrrole derivatives as potent and selective inhibitors of fibroblast growth factor receptor 1 (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)。
