The conjugates of some dicarboxylic acid hemiesters of triterpenes which show potent inhibition against human immunodeficiency virus type 1 protease (HIV-1 PR) with a reverse transcriptase inhibitor azidothymidine (AZT) or anti-HIV alkaloid FK 3000 were prepared, and their inhibitory activities were investigated against HIV-induced cytopathic effects (CPE) and HIV-1 PR. Most of the triterpene-AZT conjugates showed potent anti-HIV activity as well as moderate to potent PR inhibitory activity, though AZT itself showed no PR inhibitory activity at all. However, the triterpene-FK 3000 conjugates showed neither PR inhibitory activity nor anti-HIV activity.
本研究制备了一些对人体免疫缺陷病毒 1 型蛋白酶(HIV-1 PR)有强效抑制作用的三萜类化合物的二羧酸半酯与逆转录酶抑制剂氮卓胸苷(AZT)或抗 HIV 生物碱 FK 3000 的共轭物,并研究了它们对 HIV 诱导的细胞病理效应(CPE)和 HIV-1 PR 的抑制活性。大多数三萜类-AZT 共轭物都显示出了强效的抗 HIV 活性以及中等到强效的 PR 抑制活性,但 AZT 本身完全没有 PR 抑制活性。不过,三萜-FK 3000 共轭物既没有抑制 PR 的活性,也没有抗艾滋病毒的活性。

In the present work, we described the design, synthesis and biological evaluation of a novel series of potential dual-target prodrugs targeting the HIV-1 reverse transcriptase (RT) and nucleocapsid protein7 (NCp7) simultaneously. Among them, the most effective compound 7c was found to inhibit HIV-1 wild-type (WT) strain at double-digit nanomolar concentration (EC50 = 42 nM) in MT-4 cells, and sub-micromole

reaction energy values and the corresponding hydrolysis constants. Based on these findings, three ester based prodrugs of AZT were designed, synthesized and evaluated regarding their chemical stability. These prodrugs exhibited optimized chemical stabilities when compared to the previously reported AZT prodrugs, which may result in an enhanced pharmacotherapeutic performance. In conclusion, the developed
