  Emtricitabine Prodrugs with Improved Anti-HIV Activity and Cellular Uptake

  摘要：

  Three fatty acyl conjugates of (-)-2',3'dideoxy-5-fluoro-3'-thiacytidine (FTC, emtricitabine) were synthesized and evaluated against HIV-1 cell-free and cell-associated virus and compared with the corresponding parent nucleoside and physical mixtures of FTC and fatty acids. Among all the compounds, the myristoylated conjugate of FTC (5, EC50 = 0.07-3.7 mu M) displayed the highest potency. Compound 5 exhibited 10-24 and 3-13-times higher anti-HIV activity than FTC alone (EC50 = 0.7-88.6 mu M) and the corresponding physical mixtures of FTC and myristic acid (14, EC50 = 0.2-20 mu M), respectively. Cellular uptake studies confirmed that compound 5 accumulated intracellularly after 1 h of incubation and underwent intracellular hydrolysis in CCRF-CEM cells. Alternative studies were conducted using the carboxyfluorescein conjugated with FTC though beta-alanine (12) and 12-aminododecanoic acid (13). Acylation of FTC with a long-chain fatty acid in 13 improved its cellular uptake by 8.5-20 fold in comparison to 12 with a short-chain beta-alanine. Compound 5 (IC90 = 15.7-16.1 nM) showed 6.6- and 35.2 times higher activity than FTC (IC90 = 103-567 nM) against multidrug resistant viruses B-NNRTI and B-K65R, indicating that FTC conjugation with myristic acid generates a more potent analogue with a better resistance profile than its parent compound.

  Synthesis and Anti-HIV Activities of Glutamate and Peptide Conjugates of Nucleoside Reverse Transcriptase Inhibitors

  摘要：

  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.
