A series of 4-bromo-N-(3,5-dimethoxyphenyl)benzamide derivatives were designed and synthesised as novel fibroblast growth factor receptor-1 (FGFR1) inhibitors. We found that one of the most promising compounds, C9, inhibited five non-small cell lung cancer (NSCLC) cell lines with FGFR1 amplification, including NCI-H520, NCI-H1581, NCI-H226, NCI-H460 and NCI-H1703. Moreover, the IC50 values for the
设计并合成了一系列4-溴-N-(3,5-二甲氧基苯基)苯甲酰胺衍生物,作为新型成纤维细胞生长因子受体-1(FGFR1)抑制剂。我们发现最有希望的化合物之一C9抑制了具有FGFR1扩增作用的五种非小细胞肺癌(NSCLC)细胞系,包括NCI-H520,NCI-H1581,NCI-H226,NCI-H460和NCI-H1703。此外,化合物C9的IC50值分别为1.36±0.27 µM,1.25±0。23µM,2.31±0.41 µM,2.14±0.36 µM和1.85±0.32 µM。化合物C9使NSCLC细胞系中G2期的细胞周期停滞。化合物C9还诱导细胞凋亡并以剂量依赖的方式抑制FGFR1,PLCγ1和ERK的磷酸化。此外,分子对接实验表明化合物C9与FGFR1结合形成六个氢键。在一起
