Starting from the phase II clinical FGFR inhibitor lucitanib (2), we conducted a medicinal chemistry approach by opening the central quinoline skeleton coupled with a scaffold hopping process thus leading to a series of novel 2-benzamide-4-(6-oxy-N-methyl-1-naphthamide)-pyridine derivatives. Compound 25a was identified to show selective and equally high potency against FGFR1/2 and VEGFR2 with IC50
从II期临床FGFR抑制剂lucitanib(2)开始,我们通过打开中心喹啉骨架和脚手架跳跃过程进行了药物化学研究,从而开发出一系列新颖的2-benzamide-4-(6-oxy-N -甲基-1-萘酰胺)-吡啶衍生物。鉴定出化合物25a显示出对FGFR1 / 2和VEGFR2的选择性且同样高的效力,IC 50值小于5.0 nM。观察到对FGFR1 / 2和VEGFR2异常癌细胞均具有显着的抗增殖作用。在SNU-16异种移植模型中,化合物25a在10 mg / kg和50 mg / kg的剂量下分别显示25.0%和81.0%的肿瘤生长抑制率,体重减轻了5%和10%。鉴于在临床前研究中发现FGF和VEGF在肿瘤血管生成中具有协同增效作用,
