-Cyclodextrin (-CDE)

Molecular tus qauv:

Cyclodextrins yog tsev neeg cyclic oligosaccharide uas muaj cov nplhaib loj ntawm cov piam thaj subunits txuas los ntawm alpha-1, 4-glucoside bonds. Cyclodextrin yog tsim los ntawm enzymatic hloov dua siab tshiab ntawm starch. Ib tug raug cyclodextrin muaj ntau cov piam thaj monomers, nrog rau rau mus rau yim units nyob rau hauv lub nplhaib, tsim ib lub khob hliav qab. Gamma cyclodextrin muaj 8 qab qab zib subunits thiab muaj cov kab noj hniav loj dua betacyclodextrin, yog li cov kab noj hniav tuaj yeem suav nrog ntau yam ntawm cov qhua molecules, dej solubility zoo dua, thiab cov ntawv thov dav dua li betacyclodextrin.

Vim tias cov ntawv cog lus glucoside uas txuas cov piam thaj tsis tig tau ywj pheej, cyclodextrins tsis yog cylindrical molecules tab sis me ntsis conical rings. Vim nws cov qauv tshwj xeeb cylindrical, cov kab noj hniav sab hauv yog hydrophobic, cov kab noj hniav sab nrauv yog hydrophilic, thiab nws muaj qhov chaw chiral hauv zos. Nws cov kab noj hniav tuaj yeem ua kom haum rau ntau yam ntawm cov organic thiab inorganic me me molecules los tsim clathrates, kom cov khoom ntawm cov qhua molecules yuav hloov tau zoo heev. Yog li ntawd, cyclodextrin tuaj yeem siv los ua cov khoom siv tshiab los txhim kho qhov tsis xws luag ntawm cov tshuaj pleev ib ce.Qhov zoo ntawm cyclodextrin yog cov khoom siv thauj khoom muaj peev xwm tswj tau nws cov qauv qub, qhov loj me thiab cov yam ntxwv hauv cov kab noj hniav cyclodextrin, thiab cov khoom siv muaj peev xwm ua tau. ua tau zoo tiv thaiv cov khoom tseem ceeb los ntawm kev oxidizing, photolysis thiab thermal decomposition nyob rau hauv cov kab noj hniav, ua rau nws ruaj dua tiv thaiv ib puag ncig tej yam kev mob thiab txhim kho stability.

-Cyclodextrin tuaj yeem siv ua:

Ib qho catalyst los ua ke hloov pauv isoxazolidines ntawm 1, 3-dipolar cycloaddition ntawm nitrones nrog styrenes thiab cinnamates.

Ib qho organic ligand los ua ke cyclodextrin-based hlau-organic moj khaum siv biocompatible hlau ions.

Ib qho reactant los ua ke O-perallylated cyclodextrins ntawm perallylation nrog allyl halides nyob rau hauv lub xub ntiag ntawm NaH.

Hauv kev lag luam tshuaj pleev ib ce, cyclodextrins feem ntau yog siv los ua qhov nruab nrab thauj. Tam sim no, kev sib kis ntawm cov tshuaj pleev ib ce tuaj yeem muab faib ua plaub pawg: emulsion system, porous system, particle system thiab molecular system. Ntawm lawv, cyclodextrin yog ib qho kev thauj khoom nruab nrab. Nyob rau hauv xyoo tas los no, cyclodextrin tau siv dav hauv cov tshuaj pleev ib ce, tshuaj pleev ib ce, tshuaj zawv plaub hau, tshuaj txhuam hniav, tshuaj tsw qab thiab lwm yam khoom los txhim kho cov txiaj ntsig ntawm cov tshuaj pleev ib ce hauv kev ntxuav hniav dawb, tiv thaiv kev laus, moisturizing, pob txuv, sterilization thiab lwm yam.
