چکیده انگلیسی
The delivery of combination chemotherapy by nanoscale platforms has been demonstrated to enhance cancer treatment in the clinic. Cisplatin (CDDP)-crosslinked, glutathione-sensitive, tumor-targeting micelles based on carboxymethyl chitosan were designed for synergistic cisplatin-doxorubicin (DOX) combination chemotherapy. In our study, DOX was conjugated to carboxymethyl chitosan through a disulfide bond, which was structurally characterized by 1H NMR. The micelles formed by self-assembly were spherical, with the mean diameter of 274Â nm. The in vitro release studies revealed that the micelles were highly glutathione-sensitive. Cytotoxicity analysis demonstrated that the cisplatin-crosslinked micelles loaded with DOX exhibited enhanced therapeutic efficacy compared with the DOX-loaded nanoparticles, free DOX, and free CDDP. Cellular uptake and intracellular release revealed that the cisplatin-crosslinked micelles loaded with DOX could efficiently deliver and release DOX into the cancer cells. These results clearly indicate that tumor-targeting and glutathione-sensitive micelles provide means for combination drug delivery in cancer treatment.
