Nws cov txheej txheem ntawm kev ua haujlwm suav nrog kev ua kom Nrf2 antioxidant txoj hauv kev thiab hloov kho txoj hauv kev zoo li NF-kB .
2. Dimethyl fumarate CAS 624-49-7 kuj yog ib qho kev tshawb fawb tsis tu ncua rau kev siv tshuaj kho tshiab, suav nrog nws lub peev xwm los cuam tshuam cov kab mob angiogenesis hauv cov kab mob qhov muag xws li neovascular age-related macular degeneration (nAMD) thiab kom qeeb qhov kev loj hlob ntawm thaj chaw atrophy (GA) hauv AMD qhuav .
3. Ntxiv rau nws lub luag haujlwm tshuaj, Dimethyl fumarate yog siv rau hauv cov organic synthesis raws li dienophile hauv Diels-Alder cov tshuaj tiv thaiv thiab rau cycloadditions . Keeb kwm, nws kuj tau ua haujlwm los ua tus neeg sawv cev tiv thaiv kab mob hauv kev khaws cia cov rooj tog zaum, textiles, thiab cov khoom khaws cia, txawm tias qhov kev siv no tau txwv hauv qee thaj tsam.
Cia thiab ceev faj
1. Khaws Dimethyl fumarate rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo - qhov cua, tiv thaiv los ntawm lub teeb. Kev pom zoo cia kub sib txawv ntawm chav tsev kub (hauv qhov txias, qhov chaw tsaus) mus rau -20℃rau kev ruaj ntseg mus sij hawm ntev, nyob ntawm seb cov khoom siv thiab qhov chaw. Nws ruaj khov mus txog 4 xyoos raws li kev pom zoo.
2. Khaws Dimethyl fumarate nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua hauj, txo cov neeg ua hauj lwm, muaj zog acids, thiab muaj zog bases vim incompatibility. Nws kuj yuav tsum tau tiv thaiv los ntawm noo noo.
3. Ib txwm siv Dimethyl fumarate CAS 624-49-7 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj (nitrile roj hmab pom zoo), tsom iav kev nyab xeeb, thiab khaub ncaws tiv thaiv kom tsis txhob muaj tawv nqaij, qhov muag, thiab ua pa. Tsis txhob tsim cov plua plav thiab kov tsuas yog muaj qhov cua txaus.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav thiab ua kom muaj cua txaus. Muaj Dimethyl fumarate siv qhuav, inert, tsis yog - cov khoom siv hluav taws xob nqus tau (xws li cov xuab zeb qhuav) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej.
2. Ua tib zoo cheb Dimethyl fumarate CAS 624-49-7 siv cov cuab yeej huv si, tsis muaj teeb meem tsis muaj plua plav, thiab muab cov khoom khaws cia rau hauv cov thawv ntim khoom pov tseg, sau npe pov tseg kom raug raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv thiab tiv thaiv qhov muag thaum ntxuav. Dimethyl fumarate tsis raug cais raws li cov khoom txaus ntshai rau kev thauj los ntawm qee cov kev cai (ADR/RID, IMDG, IATA).
Cov ntaub ntawv kev nyab xeeb
1. Dimethyl fumarate yog cais nrog GHS teeb liab lo lus "Ceeb toom". Nws muaj teeb meem yog tias nqos tau (H302), tiv tauj nrog daim tawv nqaij (H312), lossis yog nqus tau (H332). Nws ua rau tawv nqaij khaus (H315) thiab khaus qhov muag loj (H319), thiab tej zaum yuav ua rau cov tawv nqaij tsis haum (H317). Cov ntaub ntawv mob toxicity qhia tau hais tias LD50 dermal (luav) ntawm 1,250 mg / kg.
2. Dimethyl fumarate muaj qhov taw tes ntawm 91-93℃thiab yog combustible . Nws cov thermal decomposition lossis combustion ua rau cov pa phem thiab ua rau khaus, nrog rau cov pa roj carbon monoxide. Nws yog tshuaj lom rau cov dej hauv dej nrog cov teebmeem ntev (H411) thiab yuav tsum tsis txhob tso rau hauv ib puag ncig.
3. Nco ntsoov sab laj Dimethyl fumarate CAS 624-49-7 Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Dimethyl fumarate kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P301+P312 rau kev noj, P302+P352 rau daim tawv nqaij, P305+P{8}P{8}, P305+P{8}}} inhalation), thiab tuav cov lus qhia. Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P273 (tsis txhob tso tawm rau ib puag ncig), P280 (hnav looj hnab looj tes tiv thaiv qhov muag), thiab P405 (khoom kaw).
