Abstract

The invention discloses application of an isobenzazole-1,3-diketone compound to preparation of a monoamine oxidase inhibitor. Through in-vitro enzyme activity test, the compound has good inhibitory activity on monoamine oxidases A and B; therefore, a reference is provided for the development of a novel MAO inhibitor, and new ideas are inspired.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a new pharmaceutical application of isoindole-1,3-diketone compounds, especially a new application in the preparation of monoamine oxidase inhibitors. Background technique [0002] Monoamine neurotransmitters include norepinephrine, epinephrine, dopamine, and serotonin, and are the most important class of neurotransmitters. The expression levels of these neurotransmitters and their metabolites are closely related to many diseases, affecting human attention, emotion and behavior. For example, a decrease in the concentration of 5-HT in the human body can cause depression; a decrease in the concentration of dopamine in the nervous system can induce Parkinson's syndrome and Alzheimer's disease. The degradation regulation of these monoamine neurotransmitters is mainly accomplished by monoamine oxidase (monoamine oxidase, MAO). Therefore, inhibiting the activity of MAO can increase the...
