Revisiting Hydrazine Moiety as a Scaffold for the Synthesis of Potential Antiviral Pyrazole Ribonucleoside Analogues. [PDF]
ChemMedChemThree series of pyrazole ribonucleoside analogues were designed and synthesized. They were evaluated, along with some of their pronucleotides, for their antiviral activity against RNA viruses. Pyrazole ribonucleoside analogues were prepared via a linear approach starting with the reaction of D‐ribosylhydrazine with 1,3‐dicarbonyl or acrylonitrile ...

Nucleobase Protection of Deoxyribo‐ and Ribonucleosides [PDF]
Current Protocols in Nucleic Acid Chemistry, 2017 AbstractOligonucleotides carrying a variety of chemical modifications including conjugates are finding increasing applications in therapeutics, diagnostics, functional genomics, proteomics, and as research tools in chemical and molecular biology. The successful synthesis of oligonucleotides primarily depends on the use of appropriately protected ...

Reversal of methylmercaptopurine ribonucleoside cytotoxicity by purine ribonucleosides and adenine [PDF]
Biochemical Pharmacology, 1995 6-Methylmercaptopurine ribonucleoside-5'-phosphate (MeSPuRMP), the sole metabolite of 6-methylmercaptopurine ribonucleoside (MeSPuRib), is a strong inhibitor of purine de novo synthesis, inducing depletion of intracellular purine nucleotides and subsequent cell death in several tumor cell lines.

Naturally occurring modified ribonucleosides [PDF]
WIREs RNA, 2020 AbstractThe chemical identity of RNA molecules beyond the four standard ribonucleosides has fascinated scientists since pseudouridine was characterized as the “fifth” ribonucleotide in 1951. Since then, the ever‐increasing number and complexity of modified ribonucleosides have been found in viruses and throughout all three domains of life.

Practical Silyl Protection of Ribonucleosides [PDF]
Organic Letters, 2013 Herein we report the site-selective silylation of the ribonucelosides. The method enables a simple and efficient procedure for accessing suitably protected monomers for automated RNA synthesis. Switching to the opposite enantiomer of the catalyst allows for the selective silylation of the 3'-hydroxyl, which could be used in the synthesis of unnatural ...
