3-b]pyridine-based inhibitors of cyclin G associated kinase (GAK) displaying low nanomolar binding affinity for GAK and demonstrating broad-spectrum antiviral activity. To come up with novel core structures that act as GAK inhibitors, a scaffold-hopping approach was applied starting from two different isothiazolo[4,3-b]pyridines. In total, 13 novel 5,6- and 6,6-fused bicyclic heteroaromatic scaffolds were synthesized
我们最近报道了细胞周期蛋白G相关激酶(GAK)的基于异噻唑并[4,3-b]吡啶的抑制剂的发现,该抑制剂对GAK具有低纳摩尔结合亲和力,并表现出广谱抗病毒活性。为了提出起GAK抑制剂作用的新型核心结构,从两个不同的异噻唑并[4,3-b]吡啶类化合物开始采用了支架跳跃法。总共合成了13种新颖的5,6-和6,6-稠合的双环杂芳族骨架。其中四个显示出GAK亲和力的Kd值处于低微摩尔范围内,可以作为基于不同支架的GAK抑制剂发现的化学起点。
