N-acetyl-L-cysteine |616-91-1
Hōʻike huahana:
ʻO ka N-Acetyl-L-cysteine kahi pauka keʻokeʻo keʻokeʻo me ka ʻala e like me ke kāleka a me ka ʻono ʻawaʻawa.
Hygroscopic, hoʻoheheʻe ʻia i ka wai a i ʻole ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka etera a me ka chloroform.He ʻakika ia i ka wai wai (pH2-2.75 i 10g/LH2O), mp101-107 ℃.
ʻO ka maikaʻi o ka N-acetyl-L-cysteine:
ʻO nā antioxidants a me nā reagents mucopolysaccharide.
Ua hōʻike ʻia e pale i ka apoptosis neuronal, akā hoʻoulu i ka apoptosis o nā ʻiʻo ʻiʻo maʻemaʻe a pale i ka hoʻopiʻi HIV.He pani no ka microsomal glutathione transferase.
Hoʻohana ʻia ma ke ʻano he lāʻau hoʻopau phlegm.
He kūpono ia no ka hoʻopaʻa ʻana i ka hanu ma muli o ka nui o ka paʻa ʻana o ka phlegm obstruction.Eia kekahi, hiki ke hoʻohana ʻia no ka detoxification o ka ʻona acetaminophen.
No ka mea he ʻala kūikawā kēia huahana, maʻalahi ke hoʻoulu i ka nausea a me ka luaʻi i ka wā e lawe ai.
He hopena hoʻoulu ia ma ka ʻōpū hanu a hiki ke hoʻoulu i ka bronchospasm.Hoʻohana maʻamau ia i ka hui pū ʻana me nā bronchodilators e like me isoproterenol, a i ka manawa like me kahi mea hoʻoheheʻe sputum.
