英文摘要 | Poly(N-trityl serine lactone)(PTSL) and mPEG-block-poly(N-trityl serine lactone)(mPEG-b-PTSL, PEG=polyethylene glycol) were synthesized via the ring-opening polymerization of N-trityl serine lactone(TSL) with diethyl zinc(ZnEt2) as catalyst. The structures of these polymers were confirmed with hydrogen nuclear magnetic resonance(H-1 NMR) spectroscopy, carbon nuclear magnetic resonance(C-13 NMR) spectroscopy and infrared(IR) spectrometer. The thermal decomposition temperature and glass transition temperature of PTSL were 241 and 161 C, respectively. A series of mPEG-b-PTSL with different molecular weights(M-n's from 7000 to 32000) was obtained by tuning the TSL/mPEG feed ratio. After the removal of the trityl groups, mPEG-block-poly(serine lactone)(mPEG-b-PSL) was obtained as a new kind of cationic block copolymer. Low cytotoxicity of these polymers to L929 cells was confirmed via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay. |
