and the first agent to be licensed for the treatment of systematic herpes virus infection in man, the corresponding 5′-O-D-valyl ester derivative has been synthesized. Based on their physicochemical properties, 5′-O-valyl ara A has emerged as a potential prodrug candidate to improve the oral bioavailability of vidarabine. We describe in this paper a facile synthesis route for the prodrug and its physicochemical
为了提高腺嘌呤 9-β-D-阿拉伯呋喃糖苷(阿糖腺苷,也称为ara A)的口服生物利用度,这是一种对单纯疱疹病毒和水痘带状疱疹病毒具有活性的抗病毒药物,也是第一个获得许可用于治疗全身性系统疾病的药物。人类疱疹病毒感染,相应的 5'-OD-缬氨酸酯衍生物已被合成。基于它们的理化特性,5'-O-valyl ara A 已成为提高阿糖腺苷口服生物利用度的潜在前药候选物。我们在本文中描述了前药及其理化性质的简便合成路线。
