The TAM kinase family arises as a new effective and attractive therapeutic target for cancer therapy, autoimmune and viral diseases. A series of 2,6-disubstituted imidazo[4,5-b]pyridines were designed, synthesized and identified as highly potent TAM inhibitors. Despite remarkable structural similarities within the TAM family, compounds 28 and 25 demonstrated high activity and selectivity in vitro against
TAM 激酶家族作为癌症治疗、自身免疫性疾病和病毒性疾病的新的有效和有吸引力的治疗靶点而出现。一系列 2,6-二取代咪唑并 [4,5- b ] 吡啶被设计、合成并鉴定为高效的 TAM 抑制剂。尽管 TAM 家族具有显着的结构相似性,化合物28和25在体外对 AXL 和 MER表现出高活性和选择性,IC 50值分别为 0.77 nM 和 9 nM,选择性为 120 至 900 倍。我们还观察到化合物10Bb的意外核定位,这要归功于 nanoSIMS 技术,这可能与三种对 TAM 抑制敏感的癌细胞系没有细胞毒性有关。
