N-acetyl-L-cysteine | 616-91-1
Incazelo Yomkhiqizo:
I-N-Acetyl-L-cysteine impushana emhlophe ecwebezelayo enephunga elifana nelikagalikhi kanye nokunambitheka okumuncu.
IHygroscopic, inyibilika emanzini noma ethanol, ayincibiliki ku-ether ne-chloroform. Ine-acidic kusisombululo esinamanzi (pH2-2.75 ku-10g/LH2O), mp101-107℃.
Ukusebenza kwe-N-acetyl-L-cysteine:
Ama-Antioxidants kanye nama-reagents e-mucopolysaccharide.
Kuye kwabikwa ukuthi ivimbela i-neuronal apoptosis, kodwa yenza i-apoptosis yamaseli emisipha ebushelelezi futhi ivimbele ukuphindaphinda kwe-HIV. Kungase kube i-substrate ye-microsomal glutathione transferase.
Isetshenziswa njengesidakamizwa esincibilikisa i-phlegm.
Ilungele ukuvimbela ukuphefumula okubangelwa inani elikhulu lokuvinjelwa kwe-phlegm okunamathelayo. Ngaphezu kwalokho, ingasetshenziswa futhi ukuqeda ubuthi obunobuthi be-acetaminophen.
Ngenxa yokuthi lo mkhiqizo unephunga elikhethekile, kulula ukubangela isicanucanu nokuhlanza lapho uthatha.
Inomphumela ovuselelayo emgudwini wokuphefumula futhi ingabangela i-bronchospasm. Ngokuvamile isetshenziswa ngokuhlanganiswa nama-bronchodilators afana ne-isoproterenol, futhi ngesikhathi esifanayo nedivayisi yokumunca isikhwehlela.
