ABSTRACT:
This invention relates to the use of certain substituted pyrrolo[2,3-d]-pyrimidine nucleosides in the treatment of viral infections, in particular those caused by human immunodeficiency virus type 1, herpes simplex virus type 1 and human cytomegalovirus. These substituted compounds retain antiviral properties present in their parent compounds yet exhibit significantly decreased levels of cytotoxicity.
