A liposome preparation based on ß-CD-LPC molecule and its application as drug-delivery system.

ABSTRACT

AIM: The ß-CD-LPC molecule was synthesized based on the conjugation of LPC and ß-CD molecules and it could self-assemble into liposome which was used to encapsulate the Dox to form nanomedicine for the cancer therapy. MATERIALS & METHODS: The anticancer and antitumor effect of ß-CD-LPC-Dox nanomedicine was studied with the vitro and vivo experimental methods. RESULTS: The result showed that ß-CD-LPC liposome had high Dox drug-loading rate and a good sustained-release effect. Cell experiment showed that the ß-CD-LPC-Dox nanomedicine could effectively induce cancer cell apoptosis and in vivo experiments showed that ß-CD-LPC-Dox liposome could effectively inhibit tumor growth and had an effective anticancer activity with lower biotoxicity. CONCLUSION: The ß-CD-LPC-Dox nanomedicine could be applied as a candidate drug to therapy the cancer.
