  Synthesis and Antiviral Evaluation of Polyhalogenated Imidazole Nucleosides:  Dimensional Analogues of 2,5,6-Trichloro-1-(β-d-ribofuranosyl)benzimidazole

  摘要：

  A series of polyhalogenated imidazole nucleosides were designed and synthesized as ring-contracted analogues of 2,5,6-trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) and its 2-bromo analogue (BDCRB) in an effort to explore the spatial limitation of the active pocket(s) in the target protein(s). 2,4,5-Trichloro-, 2-bromo-4,5-dichloro-, and 2,4,5-tribromoimidazole nucleosides were prepared by a condensation of the preformed heterocycles with the appropriate sugar precursors. The ribofuranosyl and xylofuranosyl analogues were prepared by a direct glycosylation using the Vorbruggen's silylation method and provided exclusively the beta-anomers. The arabinofuranosyl analogues were prepared by the sodium salt method to give both the alpha-and beta-anomers. The absolute configurations were established by H-1 NMR spectroscopy. Alkylation of the polyhalogenated imidazoles with the appropriate bromomethyl ethers gave the acyclic acyclovir and ganciclovir analogues. In general, the parent polyhalogenated imidazoles showed some activity against human cytomegalovirus (HCMV) (IC50 similar to 35 muM). However, with the exception of two tribromo analogues (7c, 13c-beta), most of their nucleoside derivatives were inactive against both HCMW and herpes simplex virus type-1 (HSV-1) and were not cytotoxic. The results suggest that the ring-contracted nucleoside analogues of TCRB and BDCRB interacted weakly or not at all with viral and cellular targets.
