antiviral activity displaying an EC50 of 4.69 μM against HIV-1 and an EC50 value of 0.5 μM against HBV, whereas completely lacking cytotoxicity. The synthesis of a number of phosphonomonoamidate and phosphonobisamidate prodrugs of PMDTA led to a boost in antiviral potency. The most potent congeners were a l-aspartic acid diisoamyl ester phenoxy prodrug and a l-phenylalanine propyl ester phosphonobisamidate
已经进行了具有天然核碱基腺嘌呤,胸腺嘧啶,胞嘧啶和鸟苷的四个l -2'-脱氧-苏糖酸核苷膦酸酯的合成。特别是含有腺嘌呤类似物(PMDTA)被赋予有效的抗病毒活性显示EC 50 4.69μM的抗HIV-1和EC 50针对HBV 0.5μM的值,而完全缺乏细胞毒性。PMDTA的许多膦酰单酰胺酸酯和膦酰双酰胺酸酯前药的合成导致抗病毒效力的提高。最有效的同类物是l-天冬氨酸二异戊酯苯氧基前药和l-苯丙氨酸丙酯膦酰二氨基甲酸酯前药,在低纳摩尔范围内显示抗HIV和抗HBV活性,选择性指数超过300。
