New trends in synthesis of pyrazole nucleosides as new antimetabolites

Nucleosides Nucleotides Nucleic Acids. 2005;24(8):1227-47. doi: 10.1081/NCN-200067421.

Abstract

Pyrazole nucleosides and condensed pyrazole nucleosides exhibit various biological activities. This article describes recent synthetic approaches to their preparation, chemical properties, biological activities, and structure-activity relationships, with emphasis to selected drugs or drug candidates. Two pyrazole C-nucleoside compounds pyrazofurin (pyrazomycin) and its alpha-epimer pyrazofurin B are active components of potent antivirals approved for therapeutic use in human medicine aimed against various diseases caused by DNA viruses.
