N-acetyl-l-cysteine

N-acetyl-l-cysteine ​​(NAC)yog cov organic sib xyaw, ib qho n-acetylated derivative ntawm cysteine, yog li tig mus ua viscin, yog li nws tuaj yeem siv los ua cov neeg sawv cev ua kom huv si Phlegm, purulent phlegm, thiab kev ua pa nyuaj.

1. Coj L-Cysteine ​​thiab Acetic Anhydride li cov ntaub ntawv raw, nqa tawm cov tshuaj khib nyiab, thiab ua kom zoo dua los ntawm cov carbon ntau thiab ether kom tiav cov khoom lag luamN-acetyl-l-cysteine.

2. Acetylation ntawm L-Cysteine ​​nrog Acatic Ahydride kom tau NAC
(1) nruab nrab: Dissue l-cysteine ​​hydrochloride yam tsis muaj cov dej hluav taws xob ua ntej, thiab tom qab ntawd, muab tso rau hauv dej khov kho kom sov thiab ntxiv rau hauv dej khov dej da dej kom txias thiab tom qab ntawd muab tso rau nws Mus rau hauv lub tub yees rau ib hmo, tom qab ntawd tshawb xyuas cov muaju, lim thiab ua kom muaju, ntxuav lawv nrog chcl3, thiab tom qab ntawd nias lawv kom qhuav. Ceev nrooj tso rau hauv lub tshuab nqus dej Desiccator kom qhuav, tau txais l-cysteine.
(2) acetylation: muab l-cysteine ​​rau hauv tank tiv thaiv, tricicicomomethans, ntxiv acetic anhydride nyob rau hauv lub zog ualring. Cov tshuaj tiv thaiv Tank Tsho cua sov kom txog 35 degree, tswj hwm kom muaj qhov txias, nyob rau hauv kev ua kom muaj zog, nyob rau hauv li 70 zaug kom khov, thiab tom qab ntawd ntxiv cov dej kom tsim nyog. Yog li rov qab ua dua ob peb zaug, thaum lub siab mloog rau cysteine ​​1.8 zaug lossis, crysteine ​​thaum tsaus ntuj, muab tso rau etherylconse, tau txais acetylcalyine nyoos.
(3) Kev Kho Dua: Daws cov khoom lag luam hauv {{1} etherals, muab tso rau hauv lub tub yees, ua kom lawv qhuav, thiab siv cov khoom zoo ntawm n-acetil-l-cisteina.

3. L-cisteine ​​hydrochloride (tsis muaj dej ntawm crystallization) yaj nyob rau hauv {2}}. 8 zaug tuaj yeem ua kom zoo. Tom qab ntawd lim hauv lub funnel nrog activated carbon, filtrate etherged pyridine (}} txias, thiab tom qab ntawd muab tso rau hauv lub tshuab nqus dej desiccator, chav sov kom qhuav rau 5h, kom tau l-cysteine.

1. Kws tshuaj:NacYuav siv tau mucous phlegm discolving tshuaj thiab antidotion thaiv cov tsos mob ntawm cov tsos mob ntawm kev nqus me ntsis tshwm sim los ntawm kev mob plab me.
2. Kev tshawb fawb sim: nws tuaj yeem siv ua cov khoom siv raw rau biochemical, ntxiv kev txhawb nqa zoo rau cov tshuaj tshawb nrhiav.
3. Antioxidant thiab mucopolysaccharide reagent: Qee cov kev tshawb fawb tau tshaj tawm tias nws tuaj yeem tiv thaiv cov nqaij mos ntawm lub cev cellle-ptosis thiab tuaj yeem tiv thaiv tus mob HIV. Nws muaj lub peev xwm los ua ib substrate rau micrutathione hloov chaw.

1. Cov tshuaj aqueous ntawmNacyog tus ua rau oxidation thiab tsis zoo nyob hauv huab cua, yog li nws yuav tsum npaj ua ntej siv.
2. Broncholysin yuav tsum tsis txhob siv rau hauv kev sib xyaw nrog penicillins, cepharosporins thiab tetracyclines, raws li nws yuav tau muab qhov tsis muaj txiaj ntsig.
3. Kev sib txuas lossis hloov broncholysin nrog isopropyl igninephrine yuav txhim kho kev ua tau zoo thiab txo qis kev tsis zoo.
4. Zam tsis txhob cia nws nkag mus rau hauv kev sib cuag nrog cov hlau thiab cov tais diav roj hmab, oxidizing cov neeg sawv cev, thiab cov pa oxygen; iav lossis cov tais diav yas yuav siv tau.
