the phosphoramidate ProTide approach, developed by us for antiviral nucleosides, to sugar derivatives with potential chondroprotection against osteoarthritis. In particular, N-acetylglucosamine was converted to a series of 06 arylaminoacyl phosphoramidates with ester and amino acid variation. Compounds were prepared by two routes, with or without sugar protection, and were isolated as phosphate diastereoisomers
我们报告了由我们为抗病毒核苷开发的氨基磷酸酯ProTide方法在糖衍生物中的应用,该糖衍生物具有抗骨关节炎的潜在软骨保护作用。特别地,N-乙酰氨基葡糖被转化为一系列具有酯和氨基酸变化的06个芳基氨基酰基氨基磷酸酯。通过有或没有糖保护的两种途径制备化合物,并将其分离为磷酸盐非对映异构体。测定了化合物的细胞毒性和对IL-1诱导的糖胺聚糖(GAG)从牛关节软骨体外外植体培养物中释放的抑制(即蛋白聚糖降解)。与N-乙酰氨基葡糖母体相比,某些类似物在抑制炎性细胞因子诱导的蛋白聚糖降解方面显示出显着的功效增强。
