Kev Txhaj Tshuaj-HydroxyPropyl Beta Cyclododextrin

HydroxyPropyl -Clodextrin yog ib qho ntawm cyclodextrin derivatives uas tau kawm ntau yam thiab thov feem ntau ntawm tam sim no. (Rau kev txhaj tshuaj) hydroxypropyl -chlodextrin yog dawb amorphous lossis crystalline ultrafle particle tsis muaj ntxhiab tsw thiab nrog lub qab zib me ntsis. Nws yog ib qho zoo tshaj plaws stubilizer rau kev txhaj tshuaj thiab tshuaj khaws cia.

Cov khoom lag luam

Kev qhia txog ntawm hydroxyprropyl tsoo cov benamolecular hydrogen bonds tsis pub dhau -cychlodextrin thiab ua rau nws txhaj tshuaj zoo tshaj plaws thiab kev zam. Nws cov haujlwm tseem ceeb hauv cov chaw tshuaj yog li hauv qab no:

1. Nce lub solubility ntawm cov tshuaj, uas tuaj yeem txhim kho lub hydrophilicity ntawm tsis zoo soluble thiab roj-soluble tshuaj;

2. Kev tswj hwm lossis tswj cov tshuaj tso tawm, tiv thaiv kev ua yeeb tshuaj ntawm cov tshuaj, thiab muaj cov kev thov kev pab zoo hauv cov tshuaj tiv thaiv tshuaj;

3. Txhim kho cov xyoob tshuaj, ua kom muaj kev npaj tshuaj lossis txo qis npaum li cas.

4. Txo cov tshuaj lom rau cov tshuaj lom los ntawm cov tshuaj, npog ntsej muag tsw tsw qab;

5. Txhim kho cov khoom siv ntawm cov tshuaj, thiab txhim kho kev ruaj khov yeeb tshuaj.

Cov tau txais daim ntawv thov

Injectable grade hydroxypropyl -cyclodextrin can be used in injectable formulations, mucosal delivery systems (including nasal mucosa, rectum, cornea, etc.), transdermal drug delivery systems, carriers for lipophilic targeted drugs, and also can be used as protectants and stabilizers for proteins.
