A method for treating two specific protozoal infections, Trichomonas vaginalis and Giardia lamblia, comprising the administration to a mammal in need thereof one of the following purine nucleosides: 2,6-diamino-9-(2-deoxy-2-fluoro-.beta.-D-ribofuranosyl)-9H-purine 2-amino-9-(2-deoxy-2-fluoro-.beta.-D-ribofuranosyl)-9H-purine 2-amino-9-(2-deoxy-2-fluoro-.beta.-D-ribofuranosyl)-6-methoxy-9H-purine.

Twenty purine 2'-deoxy-2'-fluororibosides were synthesized by enzymic pentosyl transfer from 2'-deoxy-2'-fluorouridine. Each nucleoside analogue was assayed for cytotoxicity in uninfected Madin-Darby canine kidney cells and for their ability to suppress influenza A virus infections in these cells. The most potent antivirial activity was observed with analogues having an amino group in the 2-position
