The present invention relates to fatty acid and fatty alcohol substituted nucleoside derivatives and nucleoside and nucleoside derivatives substituted on multivalent scaffolds (e.g., polymers, peptides, polycarboxylic acid substituted compounds, compounds containing polycycloSaligenyl groups) that display potent anti-HIV activity. Furthermore, they show enhanced activity against multi-drug resistant, R5, and cell-associated virus. Some of them also display activity against other sexually transmitted pathogens and sperm. The present invention provides their methods of synthesis, composition of matter, and methods of use. Emphasis is placed on their application as topical microbicides to treat or prevent sexual transmission of disease, especially HIV/AIDS.

Mono-, di-, and trinucleoside conjugates of glutamate or peptide scaffolds containing nucleoside reverse transcriptase inhibitors were synthesized. Among dinucleoside glutamate ester derivatives, N-myristoylated derivatives showed significantly higher anti-HIV activity than the corresponding N-acetylated conjugates against cell-free virus. Myristoyl-Glu(3TC)-FLT (46, EC50 = 0.3-0.6 mu M) and myristoyl-Glu(FTC)-FLT (47, EC50 = 0.1-0.4 mu M) derivatives were the most active glutamate-dinucleoside conjugates. A trinucleoside glutamate derivative containing AZT, FLT, and 3TC (34, EC50 = 0.9-1.4 mu M) exhibited higher anti-HIV activity than AZT and 3TC against cell-free virus. Compound 34 also exhibited higher anti-HIV activity against multidrug (IC50 = 5.9 nM) and NNRTI (IC50 = 12.9 nM) resistant viruses than parent nucleosides. The physical mixture containing FLT-succinate, AZT, 3TC, and glutamic acid exhibited 115-fold less activity against cell associated virus (EC50 = 91.9 mu M) when compared to 34 (EC50 = 0.8 mu M). Other conjugates showed less or comparable potency to that of the corresponding physical mixtures.

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-HIVactivity of synthesized compounds was evaluated against HIV-1 X4 (IIIB) and R5 (BaL) viral strains in single-round infection

contraceptive and HIV-entry inhibiting properties, and nucleoside reverse transcriptase inhibitors (NRTIs) (3′-azido-2′,3′-dideoxythymidine (AZT), 3′-fluoro-2′,3′-dideoxythymidine (FLT), or 2′,3′-dideoxy-3′-thiacytidine (3TC)) were designed to simultaneously provide contraceptive and anti-HIVactivity. Two linkers, acetate and succinate, were used to conjugate the nucleoside analogs with CS. The conjugates
