Synthesis of methylenecyclopropane analogues of antiviral nucleoside phosphonates

Nucleoside phosphate analogues of biological interest, and their synthesis via aryl nucleoside H-phosphonates as intermediates.

This review presents a brief account of the chemistry and mechanistic aspects of aryl H-phosphonates, and selected applications of this class of compounds as intermediates in the synthesis of a wide range of biologically important analogues of nucleoside phosphates, and oligonucleotides, in which the phosphate moieties are replaced by other structurally related groups. The aryl nucleoside H-pho...

Synthesis of a new family of acyclic nucleoside phosphonates, analogues of TPases transition states.

A 6-step procedure was developed for the synthesis of a new family of acyclic nucleoside phosphonates (ANPs), "PHEEPA" [(2-pyrimidinyl-2-(2-hydroxyethoxy)ethyl)phosphonic acids] in overall yields ranging from 4.5% to 32%. These compounds, which possess on one side a hydroxy function and on the other side a phosphonate group, can be considered either as potential antiviral agents or as transitio...

Antiviral activity of nucleoside analogues against norovirus.

BACKGROUND Norovirus (NoV) is the leading cause of epidemic gastroenteritis worldwide. The lack of a cell culture has significantly hampered the development of effective therapies against human NoV. Clinically approved nucleoside and non-nucleoside analogues have been used successfully against RNA viruses. METHODS In this study, we evaluated the efficacy of four nucleoside analogues (2'-C-MeC...
