Abstract

A series of 11 unsymmetrical dinucleoside dicarboxylate conjugates of nucleoside reverse transcriptase inhibitors were synthesized. Three dicarboxylic acids, succinic acid, suberic acid and 1,14-tetradecandioc acid, were diesterified with either 3'-azido- 2',3'-dideoxythymidine (AZT), 3'-fluoro-2',3'-dideoxythymidine (FLT), 2',3'-dideoxy-3'-thiacytidine (3TC) or 5-fluoro-2',3'-dideoxy-3'- thiacytidine (FTC). The anti-HIV activity of synthesized compounds was evaluated against HIV-1 X4 (IIIB) and R5 (BaL) viral strains in single-round infection assays. Results indicated that the tetradecandioate esters of nucleosides were more active against HIV than the corresponding parent nucleosides and nucleoside conjugates. The tetradecandioate conjugate of FLT and FTC (5) was found to be the most potent compound with EC50 values of 47 and 75 nM against X4 and R5 HIV-1 strains, respectively, while the EC50 values for the parent analogs, FLT and FTC, ranged from 700 to 3,300 nM.
