  Design, Synthesis, and Antiviral Activity of Certain 2,5,6-Trihalo-1-(.beta.-D-ribofuranosyl)benzimidazoles

  摘要：

  A new series of 2-substituted 5,6-dichlorobenzimidazole ribonucleosides has been synthesized and tested for activity against two human herpes viruses and for cytotoxicity. 2,5,6-Trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) was prepared by ribosylation of the heterocycle 2,5,6-trichlorobenzimidazole followed by a removal of the protecting groups. The 2-bromo derivative (BDCRB) was made in a similar fashion from 2-bromo-5,6-dichlorobenzimidazole. In contrast, the 2-iodo derivative presented a more difficult problem since the appropriate heterocycle was unavailable. This prompted us to prepare the 2-amino derivative followed by nonaqueous diazotization and removal of the blocking groups. Biological evaluation revealed marked differences in the activities of these compounds and the closely related known compound 5,6-dichloro-1-(beta-D-ribofuranosyl)benzimidazole (DRB). DRB was weakly active against both human cytomegalovirus (HCMV) and herpes simplex virus type 1 (HSV-1), (IC50's = 42 and 30 mu M, respectively) but-was cytotoxic to uninfected human foreskin fibroblasts and KB cells in the same dose range. Similar results were obtained with the heterocycle 2,5,6-trichlorobenzimidazole. In marked contrast, the ribonucleoside of 2,5,6-trichlorobenzimidazole (TCRB) was active against HCMV (IC50 = 2.9 mu M, plaque assay; IC50 = 1.4 mu M, yield assay) but only weakly active against HSV-1 (IC50 = 102 mu M, plaque assay). Little to no cytotoxicity was observed in HFF and KB cells at concentrations up to 100 mu M. By changing the substituent at the 2-position from chlorine to bromine (BDCRB), a 4-fold increase in activity against HCMV was observed without any significant increase in cytotoxicity. In contrast, the 2-I and 2-NH2 derivatives were only weakly active against HCMV and HSV-1 with activity not well-separated from cytotoxicity. These data establish that for maximum activity against HCMV with separation from cytotoxicity, ribose is preferred at the 1-position and that Cl or Br is apparently preferred at the 2-position. The activity and selectivity of both TCRB and BDCRB were better than that observed with either ganciclovir or foscarnet.
