Problems solved by technology

For many years, the main drug for clinical treatment of this disease is cholinesterase inhibitor, which acts on the cholinergic nervous system and has a relieving effect on the disease, but it cannot prevent the occurrence and development of the disease
At present, the pathogenesis of Alzheimer's disease is not very clear, but it is generally believed that the key cause of the disease is the aggregate (SP) formed by misfolding of excess β-amyloid peptide (Aβ). main component) damages cell membranes, synapses and axons, and causes neurofibrillary tangles

Abstract

This invention relates to a nitrogen-containing heterocyclic modified polyphenolic compounds and its applications. Its purpose is to provide a nitrogen-containing heterocyclic modified polyphenolic compounds and applications in the preparation of Alzheimer's disease, Parkinson's disease and other degenerative nervous system disease or type two diabetes preventing and treatment drug. Studies show that the polyphenolic compounds can inhibit aggregation of A beta, also can make the A beta aggregated depolymerize, and will eventually eliminate hydrolysis A beta protein, inhibited and removal of beta A toxicity, in the field of medicine has broad application prospects.

Description

technical field [0001] The present invention relates to polyphenolic compounds and applications thereof, in particular to polyphenolic compounds with nitrogen-containing heterocyclic modifications and their use in the preparation, treatment and prevention of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and type 2 diabetes. application in disease medicine. Background technique [0002] Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease and type 2 diabetes are protein conformation diseases. Among them, Alzheimer's disease (AD), also known as Alzheimer's disease, is a degenerative disease of the central nervous system, clinically manifested as cognitive impairment, memory loss, and eventually loss of thinking ability, movement disorders, and life. Can not take care of themselves. The pathological features are mainly senile plaque (SP), neurofibrillary tangles (neurofibrillary tangles, NFT) and selective loss of neuro...
