Fibroblast growth factor receptor (FGFR) is a potential target for cancer therapy because of its critical role in promoting cancer formation and progression. In a continuing effort to improve the cellular activity of hit compound 7r bearing an indazole scaffold, which was previously discovered by our group, several compounds harnessing fluorine substituents were designed, synthesized and biological
成纤维细胞生长因子受体(FGFR)由于其在促进癌症形成和发展中的关键作用而成为癌症治疗的潜在靶标。为了不断改善带有吲唑骨架的命中化合物7r的细胞活性(这是我们小组先前发现的),设计,合成了几种利用氟取代基的化合物,并对其进行了生物学评估。此外,还探索了向溶剂延伸至ATP结合口袋的区域。其中,含有2,6-二氟-3-甲氧基苯基残基的化合物2a表现出最强的活性(FGFR1:小于4.1nM,FGFR2:2.0±0.8nM)。更重要的是化合物2a结果显示对KG1细胞系和SNU16细胞系的抗增殖作用得到改善,IC 50值分别为25.3±4.6 nM和77.4±6.2 nM。
