英文摘要

The acidic pH in tumor tissues could be used for targeting solid tumors. In the present study, we designed a tumor-specific pH-responsive peptide H7K(R-2)(2), which could respond to the acidic pH in tumor tissues, and prepared H7K(R-2)(2)-modified polymeric micelles containing paclitaxel (PTX-PM-H7K(R-2)(2)) in order to evaluate their potential targeting of tumor cells and tumor endothelial cells and their anti-tumor activity in mice with tumor cells. PTX-FM-H7K(R-2)(2) was prepared by a thin-film hydration method. The in vitro release of PTX from PTX-PM-H7K(R-2)(2) was tested. The in vitro targeting characteristics of H7K(R-2)(2)-modified polymeric micelles on HUVEC (human umbilical vein endothelial cells) and MCF-7 (human breast adenocarcinoma cells) were evaluated. The in vivo targeting activity of H7K(R-2)(2)-modified polymeric micelles and the in vivo anti-tumor activity of PTX-PM-H7K(R-2)(2) were also investigated in MCF-7 tumor-bearing mice. The released PTX from the FTX-PM-H7K(R-2)(2) was not affected by the pH. The targeting activity of the H7K(R-2)(2)-modified polymeric micelles was demonstrated by in vitro flow cytometry and confocal microscopy as well as in vivo biodistribution. PTX-PM-H7K(R-2)(2) produced very marked anti-tumor and anti-angiogenic activity in MCF-7 tumor-bearing mice in vivo. (C) 2011 Elsevier Ltd. All rights reserved.
