Alzheimer's disease. In this study, we report lead GSK3β inhibitors identified using a fragment-linking strategy. Through the systematic exploration, a six-atom chain unit bearing the rigid double bond was found to be a suitable linker connecting two fragments, which enables favorable contacts with backbone groups of residues in the pockets. As a consequence, potent GSK3β inhibitor 9i was found with IC50 values
糖原合酶激酶3β(GSK3β)激酶可作为治疗各种人类疾病(如糖尿病,肥胖症和阿尔茨海默氏病)的有希望的治疗靶标。在这项研究中,我们报告了使用片段连接策略鉴定出的主要GSK3β抑制剂。通过系统的探索,发现带有刚性双键的六原子链单元是连接两个片段的合适连接基,可实现与口袋中残基的骨架基团的良好接触。结果,发现有效的GSK3β抑制剂9i的IC50值为19nM。结合模式分析表明,抑制剂的活性似乎是通过在GSK3β的ATP结合位点建立多个氢键和疏水相互作用来实现的。
