  Research on l-Nucleosides. synthesis and biological evaluation of a series of l- and d-2′,3′-Dideoxy-3′-[tris(methylthio)methyl]-β-pentofuranosyl nucleosides

  摘要：

  Novel nucleoside analogues of both D and L enantiomeric series were prepared by coupling reaction between a 2',3'-dideoxy-3'-modified furanose moiety and four different nucleobases. Though in all cases anomeric mixtures of nucleosides were obtained, the presence of the sterically bulky 3-tris(methylthio)methyl group allowed a good stereo selectivity level. All the compounds of both enantiomeric series showed high IC50 values as HSV-1 TK inhibitors and scarce ability to be phosphorylated by HSV-1 TK. In order to overcome possible problems related to the first phosphorylation step and to facilitate the penetration of the molecule through the cellular membrane, a monophosphate prodrug containing a long lipophilic chain was synthesized. No appreciable antiviral activity was exhibited by this molecule. (C) 2002 Elsevier Science Ltd. All rights reserved.
