Hydroxypropyl gamma cyclodextrin muaj
Khoom Description
Hydroxypropyl- gamma-cyclodextrin belongs rau cov chav kawm ntawm cyclodextrin derivatives, uas pom muaj ntau dua ntawm solubility hauv dej piv rau lawv cov niam txiv sib txuas. Nws yog dav siv nyob rau hauv parenteral formulations thiab cov ntaub ntawv ntau npaum li cas los pab nyob rau hauv kev txhim kho ntawm lawv stability, dissolution, bioavailability, thiab lwm yam.
Yam ntxwv
Hydroxypropyl gamma cyclodextrin dissolves loj molecules, xws li cholesterol, rau cell kab lis kev cai. Nws zoo ib yam li betacyclodextrin, tab sis tuaj yeem yaj cov molecules loj dua.
Daim ntawv thov
Cov dej solubility ntawm hydroxypropyl - γ - cyclodextrin tau ntxiv rau 80g / 100ml (25 ℃). Nyob rau tib lub sijhawm, hydroxypropyl - γ - cyclodextrin tsis yog ib yam khoom ntshiab, tab sis sib xyaw ntawm ntau yam hloov pauv. Nws tsis yog ib qho yooj yim los tsim inclusion complex crystal nag lossis daus thaum nws tau ua ke nrog cov qhua molecules. Feem ntau, hydroxypropyl - γ - cyclodextrin muaj ntau dua dej solubility thiab muaj zog tiv thaiv oxidation muaj peev xwm ntawm crystallization. Lub solubility ntawm γ - cyclodextrin nyob rau hauv dej yog 23.2g / 100ml (25 ℃), thiab nws daim ntawv thov yog txwv nyob rau hauv tej rooj plaub.
