N-acetyl-L-cysteine |616-91-1
Ingcaciso yeMveliso:
I-N-Acetyl-L-cysteine yi-crystalline powder emhlophe kunye nephunga elifana ne-garlic kunye ne-taste emuncu.
I-Hygroscopic, i-soluble emanzini okanye i-ethanol, i-ether kunye ne-chloroform.I-acidic kwisisombululo se-aqueous (pH2-2.75 kwi-10g/LH2O), mp101-107℃.
Ukusebenza kwe-N-acetyl-L-cysteine:
Antioxidants kunye ne-mucopolysaccharide reagents.
Kuye kwaxelwa ukuba ithintele i-neuronal apoptosis, kodwa yenza i-apoptosis yeeseli ezigudileyo zezihlunu kwaye ithintele ukuphindaphinda kwe-HIV.Isenokuba yi-substrate ye-microsomal glutathione transferase.
Isetyenziswa njengechiza lokunyibilikisa i-phlegm.
Ifanelekile ukuthintela ukuphefumla okubangelwa ubuninzi be-phlegm enamathelayo.Ukongeza, ingasetyenziselwa ukukhutshwa kwetyhefu ye-acetaminophen.
Ngenxa yokuba le mveliso inephunga elikhethekileyo, kulula ukubangela isicathulo kunye nokuhlanza xa uyithatha.
Inomphumela ovuselelayo kwindlela yokuphefumula kwaye inokubangela i-bronchospasm.Ngokuqhelekileyo isetyenziswa ngokudibeneyo ne-bronchodilators ezifana ne-isoproterenol, kwaye kwangaxeshanye kunye nesixhobo sokufunxa isikhohlela.
