  In search of flavivirus inhibitors: Evaluation of different tritylated nucleoside analogues

  摘要：

  Following up on a hit that was identified in a large scale cell-based antiviral screening effort, a series of triphenylmethyl alkylated nucleoside analogues were synthesized and evaluated for their in vitro antiviral activities against the dengue virus (DENV) and the yellow fever virus (YFV). Hereto, trityl moieties were attached at various positions of the sugar ring combined with subtle variations of the heterocyclic base. Several triphenylmethyl modified nucleosides were uncovered being endowed with submicromolar in vitro antiviral activity against the YFV. The most selective inhibitor in this series was 3',5'-bis-O-tritylated-5-chlorouridine (1b) affording a selectivity index of over 90, whereas the 3',5'-bis-O-tritylated inosine congener (5b) displayed the highest activity, but proved more toxic. The finding of these lipophilic structures being endowed with high antiviral activity for flaviviruses, should stimulate the interest for further structure-activity research.

  The triphenylmethyl (Tr) group undergoes a transfer (transetherification or disproportionation) between the molecules of 5′-O-Tr-2′-deoxynucleosides in a process mediated by anhydrous sulfates of Cu+2, Fe+2, or Ni+2 to yield mixtures of 3′,5′-bis-O-Tr and 3′-O-Tr products. If phenylmethanol is present in a reaction medium, detritylation results with concomitant formation of phenylmethyl triphenylmethyl

  在由Cu + 2，Fe + 2或Ni + 2的无水硫酸盐介导的过程中，三苯甲基（Tr）基团在5'-O-Tr-2'-脱氧核苷分子之间进行转移（转移醚化或歧化）得到3′，5′-双-O-Tr和3′-O-Tr产物的混合物。如果反应介质中存在苯甲醇，则会导致脱三苯甲基化并同时形成苯甲基三苯甲基醚。5'-O-TBDMS-2'-脱氧核苷中叔丁基二甲基甲硅烷基（TBDMS）的行为完全相同。以前没有在O-Tr和O-TBDMS组中观察到这种类型的转醚化作用。
