ABSTRACT
Aim To investigate the stabilities and related mechanism of sulfobutyl ether-β-cyclodextrin liposomes loaded with asparaginase(ASDL).Methods Reverse evaporating method was used for the preparation of ASDL,and the acid-base stability,thermal stability,antitrypsin stability,plasma stability and storage stability of ASDL were tested.Moreover,fluorescence spectrum method was utilized to explore the stability enhancement mechanisms of ASDL.Results The results of stability showed that the acid-base stability,thermal stability,antitrypsin stability,plasma stability and storage stability of ASDL were all superior to asparaginase.Fluorescence experiment results indicated that the improved characteristics of ASDL might be related to the changes of the surrounding microenvironment of fluorescent chromophore or the structure of hydrophobic.Conclusion ASDL can effectively protect asparaginase from the external environment,such as hydrolase,pH,temperature and so on,to improve the stabilities of asparaginase.
