| 英文摘要 | Pirarubicin (THP) was conjugated onto the pendant carboxyl groups of poly(ethylene glycol)-block-poly(1-lactide-co-2-methyl-2-carboxyl-propylene carbonate) [PEG-b-P( LA-co-MCC)] through hydrazone, ester, and amide bonds, respectively, and the conjugates were assembled into micelles with diameters between 30 and 60 nm. The in vitro THP release of the three conjugate micelles was conducted in pH 7.4 and 5.0 buffer solutions, and conjugate micelles with hydrazone linkage had the fastest THP release rate. Their in vitro cytotoxicity was tested using mouse mammary adenocarcinoma EMT6 cells and in vivo anti-tumor activity in Balb/c mice models bearing EMT6 tumors were compared with free THP and with each other. The results showed that the polymer-THP conjugates displayed higher cell-uptakes and better antitumor activities than free THP at 4 h, and among the three micelles, those with hydrazone linkage had the highest anti-tumor activity in vivo, while those with amide linkage were the lowest.
