N-acetyl-L-cysteine | 616-91-1
Product Description:
N-Acetyl-L-cysteine yog ib qho dawb crystalline hmoov nrog qej-zoo li tsw thiab qaub saj.
Hygroscopic, soluble hauv dej los yog ethanol, insoluble hauv ether thiab chloroform. Nws yog acidic hauv cov kua dej (pH2-2.75 hauv 10g / LH2O), mp101-107 ℃.
Kev ua tau zoo ntawm N-acetyl-L-cysteine:
Antioxidants thiab mucopolysaccharide reagents.
Nws tau raug tshaj tawm los tiv thaiv neuronal apoptosis, tab sis induce apoptosis ntawm cov leeg nqaij du thiab tiv thaiv HIV replication. Tej zaum yuav yog ib qho substrate rau microsomal glutathione transferase.
Siv los ua phlegm-dissolving tshuaj.
Nws yog qhov tsim nyog rau kev ua pa ua pa los ntawm qhov ntau ntawm cov nplaum phlegm obstruction. Tsis tas li ntawd, nws tseem tuaj yeem siv rau kev tshem tawm cov tshuaj acetaminophen lom.
Vim tias cov khoom no muaj cov ntxhiab tsw tshwj xeeb, nws yooj yim ua rau xeev siab thiab ntuav thaum noj nws.
Nws muaj cov nyhuv stimulating ntawm txoj hlab ntsws thiab tuaj yeem ua rau bronchospasm. Nws feem ntau yog siv ua ke nrog bronchodilators xws li isoproterenol, thiab tib lub sijhawm nrog cov hnoos qeev suction.
