N-Acetyl-L-cysteine inonzi acetylated amino acid ine antioxidant uye mucolytic properties.Zviitiko zviviri izvi zvakaratidza kuti N-Acetyl-L-cysteine inonyanya kukosha mumakemikari kurapwa kwe cystic fibrosis, apo iyo antioxidant / kuderedza hunhu hwekomponi inovandudza hunhu systemic redox kusaenzana kweCF uye mucolytic zvimiro zvekomboni zvinokanganisa kusangana uye kuzvimba kwakabatana neiyi redox mamiriro.Semucolytic, N-Acetyl-L-cysteine inoshumira kubvisa disulfide zvisungo mucoproteins, kusunungura uye kubvisa viscosity yesputum.N-Acetyl-L-cysteine inoratidza chiito chekurumbidza kune glutathione, zvose zvinoratidza antioxidant basa kuburikidza nekushanda kwavo kwetiol, uye zvose zviri zviviri zvinoratidzwa kudzivirira kubva kune peroxidative stress ine chokuita ne septic shock.N-Acetyl-L-cysteine yakaratidzawo kuti inokonzera apoptosis muvascular smooth muscle masero, zvichiratidza kuti masero aya anopindura zvakasiyana nekuchinja kwekuderedza-oxidation state pane mamwe matukisi anowanzo kuchengetedzwa nekuvapo kwe antioxidants.Izvi zvinoshamisa kuwirirana muvascular smooth muscle cells zvinoratidza N-Acetyl-L-cysteine sekupindira kunovimbisa pane arteriosclerotic proliferation yemasero aya.
Kemikari zvivakwa: N-acetyl-L-cysteine white crystalline poda, ine garlic-yakafanana kunhuhwirira uye kuvava kuravira.Hygroscopic, soluble mumvura kana ethanol, isinganyunguriki mu ether uye chloroform.Iyo ine acidic mune aqueous mhinduro (pH2-2.75 mu10g/LH2O), mp101-107℃Chemicalbook.Ichi chigadzirwa chinobva kuN-acetylated yecysteine.Iyo morekuru ine sulfhydryl boka, iro rinogona kutyora disulfide bond (-SS-) yemucin peptide bond, nokudaro ichishandura cheni yemucin kuita diki molecular peptide cheni, ichideredza Nekuda kwe viscosity yemucin, chigadzirwa ichi chinonyungudika. mushonga we viscous sputum, purulent sputum uye mucus wekufema.
kusangana kwemishonga:
1. Haifaniri kushandiswa pamwe chete nepenicillin, cephalosporin uye tetracycline antibiotics, sezvo iyo yekupedzisira inogona kushaya simba.
2. Kusanganiswa kana kumwe kushandiswa ne isoproterenol kunogona kuvandudza kurapa uye kuderedza maitiro asina kunaka.
3. Dzivisa kusangana nesimbi uye rabha midziyo, oxidants, uye oxygen.
Zvishandiso: biological reagents, mbishi zvinhu, thiol (-SH) mumorekuru inogona kutyora disulfide cheni (-SS) inobatanidza mucin peptide cheni mu mucous phlegm.Mucin inoshandura Chemicalbook kuita ketani diki yemolecular peptide, iyo inoderedza viscosity yesputum;inogonawo kuputsa DNA fibers mu purulent sputum, saka haigoni kungopedza white viscous sputum asiwo purulent sputum.
Zvishandiso: Mukurapa, inoshandiswa semushonga unonyungudutsa phlegm.Nekutsvagisa biochemical, inoshandiswa senge antidote yekunyungudika phlegm uye acetaminophen chepfu mumushonga.
Zvishandiso: Kutsvagisa biochemical, mukurapa, inoshandiswa senge phlegm inonyungudutsa mushonga uye antidote yeacetaminophen poisoning.
Zvishandiso: Biochemical reagents, mushonga, chigadzirwa ichi chinoshandiswa se expectorant, iyo inonzi iri nyore kuchenesa phlegm uye nyore kukosora.Iine kuora kwekuita pa viscous sputum.Iyo nzira yekuita ndeyekuti iyo sulfhydryl boka riri mumolecular chimiro chechigadzirwa ichi rinogona kutyora disulfide bond Chemicalbook mune mucin polypeptide cheni mu mucous sputum, iparadze mucin, kuderedza viscosity ye sputum, uye kuita kuti inyungudike uye nyore kuita. chikosoro.Inokodzera kune acute uye zvisingaperi zvirwere zvekufema zvine gobvu sputum uye yakaoma kutarisira, pamwe nezviratidzo zvakakomba zvekuomerwa nekusveta nekuda kwekuvhara kwehuwandu hwakawanda hwehunamira phlegm.
Zvishandiso: N-acetyl-L-cysteine inogona kushandiswa sephlegm-kunyungudutsa mushonga.Inokodzera kuvharwa kwekufema kunokonzerwa nehuwandu hwakawanda hwekunamatira phlegm kuvharwa.Uye zvakare, inogona zvakare kushandiswa pakubvisa acetaminophen chepfu.Nokuti chigadzirwa ichi chine kunhuhwirira kwakakosha, kuitora kunogona kukonzera kusvotwa uye kurutsa.Iine simba rinokurudzira pamhepo yekufema uye inogona kukonzera bronchospasm.Inoshandiswa pamwe chete nebronchodilators yakadai se isoproterenol uye sputum suction device yekudzinga sputum.Izvo hazvifanirwe kunge zvichisangana nesimbi (zvakadai seFe, Cu), rubber, oxidants, etc. Haifaniri kushandiswa pamwe chete nemishonga inorwisa mabhakitiriya yakadai se penicillin, cephalosporin, tetracycline, nezvimwewo, kuitira kuti irege kuderedza iyo antibacterial effect.Shandisa nekuchenjerera kune varwere vane bronchial asthma.
