Synthesis and antiviral evaluation of D4T analogues with a spacer arm between glucidic and base moieties

Microwave-assisted syntheses of nucleosides and their precursors

In recent decades, nucleosides analogs have been the cornerstone in the treatment of various diseases, such as AIDS, herpes and hepatitis. More than 40 modified nucleosides are officially approved by the US FDA and represent the major compound class for inhibition of viral replication. By comparison with traditional conditions, microwave irradiation offers a powerful tool that can increase yields and decrease reaction time, with simple manipulation and an environmentally friendly way. Here, we report the latest progress in nucleoside synthesis using microwave irradiation.

Synthesis and biological activity of chloroethyl pyrimidine nucleosides

The synthesis and biological activity of chloroethyl pyrimidine nucleosides is presented. One of these new nucleosides analogues significantly inhibited cell proliferation, migration and invasion as tested in vitro on the A431 vulvar epidermal carcinoma cell line.

Synthesis and antiviral evaluation of AZT analogues with A spacer arm between glucidic and base moieties. Part II

This article describes the synthesis of a series of AZT analogues bearing an acyclic chain between the sugar and the base moieties is described. These new compounds were readily obtained using microwave irradiation. The compounds were characterized by (1)H NMR and IR spectroscopy. Antiviral (HIV-1) properties of these compounds were examined.
