[PROBLEMS] To provide a neuronal cell death inhibitor and a therapeutic agent for a neurodegenerative disease, particularly Perkinson's disease.
[MEANS FOR SOLVING PROBLEMS] It is known that DJ-1 protein is involved in Perkinson's disease and is capable of inhibiting neuronal cell death caused by oxidative stress. Based on this knowledge, screening is made for a low molecular weight molecule capable of binding to an active site of DJ-1 protein (i.e., a region around a cysteine residue at position-106) using an analysis softwear FastDock (Fujitsu Ltd.). When various tests are made using candidate low molecular weight compounds each having a binding energy of -60 kcal/mol or lower, these compounds show a therapeutic effect on a neurodegenerative disease.

[解决问题的方法] 已知 DJ-1 蛋白与帕
金森氏症有关,并能抑制氧化应激引起的神经
细胞死亡。根据这一知识,使用分析软件 FastDock(富士通有限公司)筛选能够与 DJ-1 蛋白质的活性位点(即位于第 106 位的半胱
氨酸残基周围区域)结合的低分子量分子。使用结合能为-60 kcal/mol或更低的候选低分子量化合物进行各种测试时,这些化合物显示出对神经退行性疾病的治疗效果。
