摘要
The photodegradation of doxorubicin (Dox) in the presence of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was studied; the degradation rate constant in the presence of HP-beta-CD estimated by Lineweaver-Burk analysis was approximately three times lower than that of free Dox aqueous solution, which shows that HP-beta-CD can enhance the photostability of doxorubicin aqueous solution. The enhancement may be attributed to the inclusion interaction between HP-beta-CD and doxorubicin. The characterization of FTIR, DSC, XRD and fluorescence titration indicates that 1 : 1 inclusion complex is formed between HP-beta-CD and doxorubicin.
