摘要: Deoxycholic acid hydrophobically modified-carboxymethylated-curdlan (DCMC) conjugate was developed as a novel carrier for the anticancer drugs. Epirubicin (EPB), model drug, physically loaded into DCMC self-assembled nanoparticles. EPB-loaded nanoparticles were almost spherical in shape and their size, range of 327.4-511.5 nm, increased with EPB-loading content increasing. In vitro release EPB from showed sustained drug pattern rate related to pH media loading content. The cytotoxic activity assayed by MTT colorimetric assay. Compared free higher cytotoxicity, which may be attributed enhanced cellular uptake. vivo toxicity study indicated that did not induce unexpected side effects. Tissue biodistribution performed tumor-bearing mice. result uptake tumor decreased kidney heart, compared drug. Moreover, volume reductions induced conjugate, EDNs 24.3%, 58.9% 70%, respectively, suggested could effectively retard growth tumor.
