Glycogen synthase kinase-3β (GSK-3β) represents a relevant drug target for the treatment of neurodegenerative pathologies including Alzheimer’s disease. We herein report on the optimization of a novel class of GSK-3β inhibitors based on the tofacitinib-derived screen hit 3-((3R,4R)-3-((7-chloro-9H-pyrimido[4,5-b]indol-4-yl)(methyl)amino)-4-methylpiperidin-1-yl)-3-oxopropanenitrile (1). We synthesized
糖原合酶激酶-3β (GSK-3β) 是治疗神经退行性疾病(包括阿尔茨海默病)的相关药物靶点。我们在此报告了基于托法替尼衍生的筛选命中 3-((3R,4R)-3-((7-chloro-9H-pyrimido[4,5-b]吲哚-4-基)(甲基)氨基)-4-甲基哌啶-1-基)-3-氧代丙腈 (1)。我们合成了一系列 19 种新型 7-氯-9H-嘧啶基[4,5-b]吲哚衍生物,并重点研究了它们的构效关系,重点关注氰基乙酰哌啶部分。我们揭示了腈基的关键作用及其对该化合物系列活性的重要性。一种成功的硬化方法提供了 3-(3aRS,7aSR)-(1-(7-chloro-9H-pyrimido[4,5-b]indol-4-yl)octahydro-6H-pyrrolo[2,3-c]pyridin -6-基)-丙腈(24),它在 GSK-3β 上显示出 130 nM 的 IC50 值,并进一步以其代谢稳定性为特征。最后,我们通过
