Novel purpose of S-(carboxymethyl)-L-cysteine

Abstract

The invention relates to a novel purpose of medicine, in particular to application of S-(carboxymethyl)-L-cysteine and pharmacologically acceptable salts of the S-(carboxymethyl)-L-cysteine to prevention and / or treatment of respiratory system diseases and the like caused by haze. The S-(carboxymethyl)-L-cysteine and the pharmacologically acceptable salts of the S-(carboxymethyl)-L-cysteine are used; and the inflammation damage and oxidation operation of atmosphere PM2.5 on the lungs of mice can be obviously reduced, so that the S-(carboxymethyl)-L-cysteine and the pharmacologically acceptablesalts of the S-(carboxymethyl)-L-cysteine can be applied to preparation of medicine for preventing and treating diseases caused by haze.

Description

technical field [0001] The invention relates to the field of medicine, in particular, the invention relates to a new medicine application of S-(carboxymethyl)-L-cysteine ​​and a pharmaceutically acceptable salt thereof. Background technique [0002] The clinical manifestations of diseases caused by smog are not exactly the same as those of the same disease caused by other reasons. Taking COPD as an example, the smoke produced by the combustion of biofuels (including firewood, wood, charcoal, crop stalks and animal manure, etc.) is one of the main sources of smog ( Ran Pixin. The role of biofuels in the pathogenesis of chronic obstructive pulmonary disease should not be ignored. Chinese tuberculosis and respiratory Journal, 2010, 33(4): 241-242. ), the clinical features of COPD caused by it (referred to as "B-COPD") and smoking-induced COPD (referred to as "T-COPD") are very different. B-COPD patients are more common in women, with low body mass index (BMI) , more clinical...
