Parkinson’s disease (PD) is a chronic degenerative disorder characterized by typical motor symptoms caused by the death of dopamine (DA) neurons in the midbrain and ensuing shortage of DA in the striatum, at the level of nerve terminals. No curative treatment is presently available for PD in clinical practice. In our search for neuroprotectants in PD, we generated new 1,4,8-triazaphenanthrenes by combining
帕金森氏病(PD)是一种慢性退行性疾病,其特征是典型的运动症状,由中脑中的多巴胺(DA)神经元死亡以及纹状体中神经末梢水平的DA缺乏引起。目前在临床实践中尚无可用于PD的治疗方法。在寻找PD中的神经保护剂时,我们通过结合炔丙基喹喔啉的6-内-dig-环异构化和Suzuki或Sonogashira交叉偶联反应生成了新的1,4,8-三氮杂菲。在PD细胞模型中对新合成的1,4,8-三氮杂菲的神经保护评估导致发现了一种新的命中化合物PPQ(5m)。5m的神经保护是浓度依赖性的,并且是对细胞内钙释放通道和星形胶质细胞联合作用的结果。有趣的是,5m还可以抵消PD小鼠模型中DA细胞的丢失,使该分子成为PD治疗的有希望的候选者。
