Deoxyribonucleoside 2‘- or 3‘-Mixed Disulfides: Prodrugs To Target Ribonucleotide Reductase and/or To Inhibit HIV Reverse Transcription
摘要:
Herein, we report the design, synthesis, and biological effects of nucleosides bearing a disulfide function on the sugar ring as prodrugs of potentially active mercapto-nucleotides that can target ribonucleotide reductase or reverse transcriptase. We show that cytidine derivatives efficiently reduce dNTP pools in human CEM/SS cells and that 3'-deoxythymidin-3'-yl methyl disulfide is able to interfere with both cellular dNTP synthesis and HIV reverse transcription.
2-Trimethylsilylethyl Sulfides in the von Braun Cyanogen Bromide Reaction: Selective Preparation of Thiocyanates and Application to Nucleoside Chemistry
Mixed 2-(trimethylsilyl)ethyl sulfides were synthesized and used in the von Braun cyanogen bromide reaction for preparing selectively thiocyanates in high yield. We show here that this cleavage reaction is highly selective in methanol in comparison with the reaction of the corresponding non-silyl sulfide analogues. This reaction was applied to the synthesis of nucleosidic thiocyanates such as the new
