The present invention provides a pharmaceutical composition for preventing and treating central nervous system (CNS) diseases, diabetes and complications thereof, the pharmaceutical composition comprising, as an active ingredient, a benzimidazole or benzoxazole derivative having the structure of chemical formula 1 or a pharmaceutically acceptable salt thereof. The benzimidazole or benzoxazole derivative used as an active ingredient in the pharmaceutical composition of the present invention can, via an Nrf2 activation mechanism caused by the Keap1-Nrf2-ARE pathway and via an activation pathway of glutamate transporters such as GLT-1/EAAT and GLAST, inhibit oxidative damage in the central nervous system and the pancreas while inducing production of an antioxidant such as glutathione, thereby maximizing the effect of treating central nervous system diseases, diabetes and complications thereof. |
