that inhibit HIV-1-induced syncytia formation with IC50 values of 7, 18, and 24 m̈M for 39, 29, and 42, respectively, and inhibit HIV-1 reverse transcriptase (RT) activity from 14 to 96% (see Table). Of the nine conjugates tested, inhibition of HIV-1 replication by 28, 29, 32, 40, and 42 may be attributed in part to the activation of the RNase L/PKR antiviral pathways. Trimer conjugate 42 showed the greatest
抗病毒活性3'-脱氧腺烯基-(2'-5')-3'-脱氧腺烯基-(2'-5'的可生物降解的2'-和5'-酯和2'-和5'-碳酸酯结合物的合成首先通过制备获得具有维生素E,D 2和A以及脂质1,2-二-O-棕榈酰甘油和1,2-二-O-十六烷基甘油的)-3'-脱氧腺苷(cordycepin-三聚体核心)三聚体离析物19-21(方案1)。其次,这些物质通过琥珀酸酯或碳酸盐连接基与亲脂性残基缩合,然后通过β-消除npeoc和npe保护基团进行脱保护,并进行酸处理以进行去三苯甲基化反应,而不会分别损害酯和碳酸盐的功能(方案2)。代谢稳定的虫草素-三聚体的维生素和-脂质共轭物是一类新生物缀合物的抑制HIV-1的诱导的合胞体形成的IC 50个值的7,18,和24毫米为39,29,和42,分别和禁止HIV-1逆转录酶(RT)活性从14%上升到96%(请参阅表)。在测试的九种结合物中,HIV-1复制受到28、
