non-small-cell lung cancer clinically. Aiming to explore new potent inhibitors, a series of 2-amino-4-(1-piperidine) pyridine derivatives that stabilized a novel DFG-shifted conformation in the kinase domain of ALK were designed and synthesized on the base of lead compound A. Biological evaluation highlighted that most of these new compounds could also potently inhibit ROS1 kinase, leading to the promising inhibitors
自从克唑替尼被临床用于治疗非小细胞肺癌以来,ALK和ROS1激酶已成为有希望的治疗靶标。为了探索新的有效抑制剂,在铅化合物A的基础上设计并合成了一系列2-氨基-4-(1-哌啶)吡啶衍生物,这些衍生物在ALK激酶域中稳定了新的DFG移位构象。评估强调,这些新化合物中的大多数也可以有效抑制ROS1激酶,从而成为有前景的针对ROS1和ALK的抑制剂。其中,代表性化合物2e对ALK上瘾的H3122和ROS1上瘾的HCC78细胞系(IC 50 分别为6.27μM和10.71μM)具有很强的抗增殖活性,与克唑替尼相当。而且2e对临床上耐克唑替尼的ALK L1196M表现出令人印象深刻的酶活性,IC 50值为41.3 nM,比克唑替尼的效价高约2倍。2e还显示出在含有ROS1 G2032R的Ba / F3细胞系中强效抑制活性比克唑替尼高约6倍(IC 50:104.7 nM对643.5 nM)。此外,分子
