Microtubule is one of the important targets for cancer treatment. A novel class of diaryl substituted imidazo[4,5-c]pyridin-2-ones and imidazo[4,5-c]pyridines were designed based on combination principles by merging the structures of β-lactams and purine-type compounds known as tubulin polymerization inhibitor and katanin activity up-regulator, respectively. Their antitumor activities were evaluated
微管是治疗癌症的重要靶标之一。基于结合原理,通过结合β-内酰胺和嘌呤类化合物的结构,设计了一类新型的二芳基取代的咪唑并[4,5-c]吡啶-2-酮和咪唑并[4,5-c]吡啶。微管蛋白聚合抑制剂和katanin活性上调剂分别。在体外评估了它们的抗肿瘤活性并阐明了其机制,从而鉴定出1,6-二芳基-1 H-咪唑并[4,5-c]吡啶2-2(3 H)-one 20b作为第一种双功能剂可以同时靶向微管蛋白和katanin。在体内测定证实化合物20b的 具有良好的药代动力学特征,可显着抑制异种移植肿瘤的生长,这表明它具有进一步发展成为具有双重靶向微管独特机制的抗肿瘤药物候选物的潜力。
