Compounds of Formula I, Formula II, Formula III, Formula IV, Formula V, Formula VI, Formula VII, Formula VIII, Formula IX and Formula X that are highly active against the HCV virus when administered in an effective amount to a host in need thereof. The host can be a human or any animal that carries the viral infection. Methods of treating a subject suffering from a condition related to viral infections are also provided.
The present invention relates to 3'-azido purine nucleosides and their use in medical therapy, particularly for the treatment of human immunodeficiency virus and hepatitis B virus infections, to methods for their preparation and to compositions containing them.
An efficient and facile three-component Mannich-type reaction on purine rings was described. This reaction proceeded smoothly under the catalysis of ethylenediamine at ambient temperature in high regioselectivities with exclusive N9-alkylated products. A wide range of purine derivatives were obtained in high yields.
