Abstract

The invention discloses a kind of halogenated benzenediol glucosides, and as shown in logical formula (I), the preparation method of this kind of compound, this kind of compound and the pharmaceutical composition containing this kind of compound are in the new opplication for inhibiting neural microglia aspect of inflammation.

Description

The preparation method and its pharmaceutical usage of halogenated benzenediol glucoside
Technical field
The invention belongs to drug fields, and in particular to the preparation method of halogenated benzenediol glucoside and its inhibit nerve The new opplication of microglia aspect of inflammation.
Background technique
Neural microglia is the immunocyte resided in brain and spinal cord, protects central nervous system from invading It attacks.In the case where neurodegenerative disease, headstroke and brain are wound, microglia is activated, and by chemotactic to sense It contaminates position and external infection source or impaired tissue is cleared up by phagocytosis.Although the microglia of activation generates many beneficial Effect, but it continues excessive inflammatory reaction can cause more unfavorable permanent damage to brain tissue[1].Academia is general All over thinking that neuroinflamation Ahl tribulus sea silent sickness and Parkinson's disease caused by Activated Microglia are closely related[2]
Interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) be in neuroinflamation main pro-inflammatory cellular because Son[3].TNF-α is originally described as a kind of cytotoxicity substance, can selective killing tumour cell, later find TNF-α also plays critical function during inflammatory reaction after cellular informatics transmitting, infection and wound.TNF-α can induce flower The release of raw tetraenoic acid metabolin and the generation of lipoperoxide and oxygen radical, above-mentioned substance have serious damage cell membrane Effect[4].IL-6 is not only important inflammatory molecule, but also increases amyloid precursor protein gene (APP) and generate, and promotes Beta-amyloid protein (amyloid β-protein, A β) aggregation, all many-sided play such as activating complement damaged nerve cells are imitated It answers[5]
Due to weight of the neuroinflamation in terms of neurodegenerative disease (Alzheimer disease, Parkinson's disease etc.) occurrence and development It acts on, inhibits inflammatory factor, alleviating neuroinflamation becomes the important channel for the treatment of neurodegenerative disease[4].Polyphenols chemical combination Often have anti-oxidant, anti-inflammatory isoreactivity, natural polyphenol class compound, curcumin anti-neuroinflamation effect it is verified that[6]。 Bibliography
