ABSTRACT
AIM:
Tumor metastasis is one of the leading causes of insufficient chemotherapy during cancer treatment. In this study, a poly(ß-amino ester) derivate was developed to fabricate paclitaxel (PTX) entrapped pH-responsive copolymer micelles for inhibition of breast cancer metastasis. MATERIALS &METHODS:
PTX-loaded micelles were fabricated by thin film hydration method. The inhibition efficacy of the as-prepared micelles was evaluated on MDA-MB-231 cells and tumor bearing mice.RESULTS:
PTX-loaded micelles were successfully prepared. Such micelles could promote drug uptake and MDA-MB-231 cell deaths, and suppress tumor metastasis.CONCLUSION:
The pH-responsive PTX-loaded micelles are promising candidates in developing stimuli triggered drug delivery systems in acidic tumor microenvironments with improved inhibitory effects on tumor metastasis.Palavras-chave
