Definitions
- the present invention relates to isoxazole derivatives having excellent A-type monoamine oxidase inhibitory activity or pharmacologically acceptable salts thereof, and depression, Parkinson's disease, Alzheimer's disease (based on Alzheimer's disease) comprising them as active ingredients.
- a composition for the treatment or prevention of neurological diseases (particularly depression) such as cerebrovascular dementia (cognitive impairment based on cerebrovascular dementia) or for the treatment or prevention of the above diseases And / or administering a pharmacologically effective amount thereof to a warm-blooded animal.
- Depression is a mood disorder whose main symptom is suppression of mood. It is thought that one of the causes is dysfunction of the brain serotonin and noradrenaline nervous system. Serotonin and noradrenaline are mainly degraded and metabolized by monoamine oxidase A among monoamine oxidases to lose biological activity. Type A monoamine oxidase inhibitors are considered to be useful as antidepressants, and research and development has been actively conducted. In recent years, Mokuchibemide has been clinically provided as a selective A-type monoamine oxidase inhibitor.
- isoxazole derivatives having a unique structure are powerful.
- the present invention has been completed.
