A new series of hitherto unknown 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA) phosphonodiester derivatives incorporating carboxyesterase-labile S-acyl-2-thioethyl (SATE) moieties as transient phosphonate-protecting groups was prepared in an attempt to increase the oral bioavailability of the antiviral agent PMEA. We report here a direct comparison of the in vitro anti-HIV and anti-HSV activities as
制备了一系列迄今未知的新的9- [2-(膦酰基甲氧基)乙基]腺嘌呤(PMEA)磷酸二酯衍生物,其中掺入了不稳定的羧酸酯酶S-酰基-2-硫代乙基(SATE)部分作为瞬时膦酸酯保护基,以试图增加抗病毒药物PMEA的口服生物利用度。我们在这里报告了bis(SATE)衍生物与已知的PMEA前药即bis [(pivaloyloxy)methyl(POM)之间的体外抗HIV和抗HSV活性以及体外稳定性的直接比较。 ]-和双[二硫代二乙基(DTE)] PMEA。与母体PMEA相比,所有测试的化合物均显示出增强的体外抗病毒活性。bis(POM)-和bis(tBu-SATE)PMEA衍生物最有效。但是,在稳定性研究中发现了这两种化合物之间的显着差异。
