HO-protected and -unprotected d -glucopyranosyl esters of N -acylamino acids (Gly, Ala, Phe) with glycine and phenylalanine methyl esters in N , N -dimethylformamide at 38° and dichloromethane at 40°, respectively, led to rupture of the C-1 esterbond and formation of the corresponding N -acyldipeptide methyl ester. The relative reactivity of the C-1 esterbond toward aminolysis was greatly influenced by

[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.
