  Nucleotides, Part LIX, Synthesis, Characterization, and Biological Activities of New Potential Antiviral Agents: (2′ - 5′)Adenylate Trimer Analogs Containing 3′-Deoxy-3′-(hexadecanoylamino)adenosine at the 2′-Terminus

  摘要：

  Based upon 3'-amino-3'-deoxyadenosine (15), its protected 3'-hexadecanoylamino derivative 22 was chosen as starting material for the synthesis of a series of new modified 2'-5'-adenylate trimers 33-36 as potential antiviral agents. All (2'-5')A trimer analogs 33-36 inhibit HIV-1 replication as measured by the inhibition of syncytia formation and inhibition of HIV-1 reverse transcriptase activity. Compound 34 inhibits HIV-1 reverse transcription by 100% and subsequently inhibits expression of HIV-1 p24. However, compound 35 acts differently, since it does not inhibit HIV-1 reverse transcription, HIV-1 integrase, or HIV-1 p24 expression. Therefore, 35 appears to exert its inhibitory effect at a later stage of HIV-1 replication, i.e., the budding process.
