We here disclose chemical synthesis of ribonucleoside 5′-monophosphate (RMP), -diphosphate (RDP), and -triphosphate (RTP) and cycloSal-, DiPPro-, and TriPPPro nucleotide prodrugs of the antiviral pseudobase T-1105. Moreover, we include one nucleoside diphosphate prodrug of the chemically less stable T-705. We demonstrate efficient T-1105-RDP and -RTP release from the DiPPro and TriPPPro compounds by
我们在这里公开了抗病毒假碱基T-1105的核糖核苷5'-单磷酸酯(RMP),-二磷酸酯(RDP)和-三磷酸酯(RTP)和环Sal-,Di PP ro-和Tri PPP ro核苷酸前药的化学合成。。此外,我们包括一种化学稳定性较差的T-705核苷二磷酸前药。我们展示了有效的T-1105-RDP和-RTP通过酯酶激活从Di PP ro和Tri PPP ro化合物中释放出来。使用粗酶提取物,我们看到T-1105-RDP迅速磷酸化为T-1105-RTP。与之形成鲜明对比的是,未观察到T-1105-RMP的磷酸化,这表明T-1105的代谢活化仍未识别出瓶颈。因此,Di PP ro和TriPPP ro化合物显示出针对甲型和乙型流感病毒的改善的细胞培养活性,它们保留在无法激活核碱基亲本的突变细胞系中。T-1105-RTP对分离的流感病毒聚合酶具有很强的抑制作用,而Di PP ro-T-1105-RDP在
