[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.

content on the modified surfaces prepared with OMeDA was 187% higher than that obtained with dopamine, and the antibacterial efficacy of the former against Staphylococcus aureus was correspondingly higher than that of the latter. This study demonstrates that OMeDA with an electron-donating group in the catechol ring offers improvements over dopamine for surfacemodification applications.
