Nucleoside 5'-triphosphates (NTPs) play key roles in biology and medicine. However, these compounds are notoriously difficult to synthesize. We describe a one-pot method to prepare NTPs from nucleoside 5'-H-phosphonate monoesters via pyridinium phosphoramidates, and we used this approach to synthesize ATP, UTP, GTP, CTP, ribavirin-TP, and 6-methylpurine ribonucleoside-TP (6MePTP). Poliovirus RNA-dependent RNA polymerase efficiently employed 6MePTP as a substrate, suggesting that the cognate nucleoside, a poorly understood antiviral agent, may damage viral RNA.
核苷5'-三磷酸(NTPs)在生物学和医学中发挥着关键作用。然而,这些化合物极难合成。我们描述了一种通过吡啶鎓氨基磷酸酯从核苷5'-H-膦酸单酯制备NTPs的一锅法,并且我们使用这种方法合成了ATP、UTP、GTP、CTP、利巴韦林-TP和6-甲基嘌呤核糖核苷-TP(6MePTP)。脊髓灰质炎病毒RNA依赖性RNA聚合酶有效地将6MePTP用作底物,这表明同源核苷(一种了解甚少的抗病毒剂)可能会破坏病毒RNA。
