Problems solved by technology

Due to the complex pathogenesis of Alzheimer's disease, the above drugs can only alleviate or inhibit the disease, but cannot completely cure it
Since the therapeutic effect of drugs targeting a single target is single and the pertinence is not high, more and more researches are biased towards the development of dual-target or multi-target drugs, targeting multiple targets of disease occurrence, which may make it The curative effect is enhanced, making up for the shortcoming of a single drug with a single effect, and improving the therapeutic effect

Abstract

The invention provides a coumarin / pyridine hybrid derivative shown as the formula (I) or the formula (II) and pharmaceutically acceptable salt thereof. The coumarin / pyridine hybrid derivative and thepharmaceutically acceptable salt thereof can be applied in preparation of anti-Alzheimer and antiparkinsonian drugs or drugs for treating other diseases by inhibiting MAOs (monoamine oxidases) or chelating iron ions.

Description

technical field [0001] The invention relates to the fields of organic synthesis and medicinal chemistry, in particular to a class of dual-target anti-Alzheimer's coumarin / pyridone hybrid derivatives with monoamine oxidase inhibitory effect and iron ion chelating ability and preparation thereof Methods and uses in the treatment of Alzheimer's disease. Background technique [0002] Alzheimer's disease (Alzheimer's disease, AD) is the most common degenerative disease of the central nervous system in middle-aged and elderly people, mainly manifested by cognitive and behavioral dysfunction. With the increase of global aging and the increasing pollution of the environment, Worldwide, this disease has become a serious disease that threatens human health after cardiovascular disease and tumors, especially in China. Because Alzheimer's disease can cause patients to be unable to take care of themselves, it has caused serious harm to human health and social stability. In recent years...
