N,N′-(pyromellitoyl)-bis-l-tyrosine dimethyl ester (7) as a chiral bioactive diphenolic monomer was prepared in three steps. The aim of this work was to obtain novel optically and biologically active pseudo-poly(amino acid)s (PAA)s that are more soluble in common organic solvents while maintaining their high thermal stability. Thus, several new, highly soluble, thermally stable, optically active and
在该研究中N, ' - (pyromellitoyl) -双-升-酪氨酸甲酯(7),为手性的生物活性在三个步骤制备双酚单体。这项工作的目的是获得新型的光学和生物活性假聚(氨基酸)(PAA),它们在普通的有机溶剂中更易溶,同时保持其高的热稳定性。因此,通过使用甲苯磺酰氯,吡啶和N,N通过直接缩聚反应,制备了几种新的,高溶解性,热稳定,光学活性和可生物降解的主链中包含不同氨基酸部分的PAA,它们具有中等分子量。′-二甲基甲酰胺作为缩合剂。用FT-IR,1 H-NMR,元素和热重分析技术对所得的新型聚合物进行表征。此外,在培养基中对双酚单体7,不同的合成二酸(3a - 3e)和获得的PAA进行了体外毒性和生物降解性研究,结果表明合成的化合物和由其衍生的聚合物具有生物活性和可生物降解性。在自然环境下。
