Herein, we report the synthesis of a library of new s-triazine polyamides containing glycine and thioglycolic acid. The reaction of s-triazine dicarboxylic acid derivatives with ethylenediamine, benzidine, piperazine, or p-phenylenediamine, afforded the target designed s-triazine polyamides. The thermal properties of the polymers were evaluated by different techniques, and the thermodynamic parameters
在此,我们报告了包含甘氨酸和巯基乙酸的新的S-三嗪聚酰胺库的合成。的反应小号嗪与乙二胺,联苯胺,哌嗪,或二羧酸衍生物p苯二胺,得到目标设计小号-三嗪聚酰胺。通过不同的技术评估聚合物的热性能,并评估分解过程的热力学参数。研究了合成聚合物作为药物纳米递送系统的可行性。纳米颗粒中装载了塞来昔布(CXB),这是一种抗炎药,具有高度有望的抗癌作用,可导致较高的包封率(62.3–99.8%),载药量在1.58–4.19%之间。48小时,46.90,64.20,57.81,53.95,和CXB的49.43%后,从聚合物纳米颗粒释放的26,43,44,45,和46分别展示了持续的药物释放曲线。值得注意的是,游离的CXB和载有CXB的聚合物NP CXB-43,CXB-45和CXB-46以剂量依赖的方式显示出细胞活力的显着降低。
