synthetic strategy for polymers containing amino acids in the main chain was developed. Monomers N‐oxetanylalanine (N‐Oxe‐Ala‐COOH), N‐oxetanylglutamic acid (N‐Oxe‐Glu‐COOH), and N‐oxetanyllysine (N‐Oxe‐Lys‐COOH) containing both oxetanyl and carboxyl groups were synthesized, and self‐polyaddition and self‐copolyaddition of these monomers afforded the corresponding polymers containing amino acids in the main
开发了一种新的合成策略,用于在主链中包含氨基酸的聚合物。单体Ñ -oxetanylalanine(Ñ -Oxe-ALA-COOH),Ñ -oxetanylglutamic酸(Ñ -Oxe-GLU-COOH),和Ñ -oxetanyllysine(Ñ同时含有氧杂环丁烷基和羧基基团-Oxe赖氨酸-COOH)的合成,并通过这些单体的自加聚和自共聚得到了主链中含有氨基酸的相应聚合物[聚(Ox Ala),聚(Ox Lys),聚(Ox Glu),聚(Ox Ala- co - Ox Glu ),聚(Ox Glu‐共-牛赖氨酸),和聚(牛ALA-共-牛赖氨酸)]与分子量在920-6620的范围内,在令人满意的产率。物理性质,例如溶解度,玻璃化转变温度和热稳定性,与链末端的羧基数量一致。通过生化需氧量法检查了聚合物的生物降解性;聚的分解率(牛ALA)和聚(牛ALA-共-牛谷氨酸)为约60%,而聚(牛谷氨酸)在28天后为接近100%。©2011
