Novel symmetrical nucIeotide-(5′,5′)-dimers of 3′-O-acetylthymidine, 3′-O-methylthymidine, 3′-O-ethylthymidine, 3′-O-n-propylthymidine and 3′-azido-3′-deoxythymidine (AZT) were synthesized as membrane soluble pro-drugs. These were prepared using phosphorodichloridate chemistry and were characterised by spectroscopic and analytical data. In-vitro evaluation of the derivatives in cells acutely infected with the human immunodeficiency virus (HIV-1) demonstrated a range of activities. These derivatives were generally found to display poor inhibition of HIV proliferation. Derivatives containing AZT moieties were found to be potent, but such compounds were less active than the parent nucleoside. The data indicated that the AZT-containing compounds act primarily via the release of the free nucleoside. However, in some cases, the dimers of certain inactive nucleoside analogues were found to be active. In these cases, release of the nucleoside alone cannot account for the activity.

Ingenol 3,5,20-triacetate has recently been identified as a highly potent and selective inhibitor of HIV replication in vitro. To evaluate the potential of ingenol derivatives as anti-HIV agents, several ingenol derivatives have been synthesized and investigated for their anti-HIV activities, structure-activity relationships, and possible mechanisms of action. Among the ingenol derivatives, 13-hydroxyingenol-3-(2,3-dimethylbutanoate)-13-dodecanoate (RD4-2138) proved to be a highly potent and selective inhibitor of HIV replication. Its 50% effective concentration for viral replication in MT-4 cells was 0.07-0.5 nM depending on viral strains, including HIV-2. This concentration was approximately 105-fold lower than its cytotoxic threshold. RD4-2138 was also inhibitory to the syncytium formation induced by cocultivation of Molt-4 cells with Molt-4/IIIB cells (Molt-4 cells chronically infected with HIV-1). Some correlation was observed with the ingenol derivatives between their inhibitory effects on HTLV-IIIB replication and surface CD4 expression in MT-4 cells, suggesting that the mechanism of inhibition is in part attributed to the inhibition of virus adsorption through down-regulation of CD4 molecules in the host cells. However, such correlation was not identified between the inhibition of HTLV-IIIB and the activation of protein kinase C. Thus, they might have a potential as effective anti-HIV agents when toxicity in vivo could be elucidated.
