Phosphonate acyclic derivates of guanines, pyrazolo[3,4-d]pyrimidines, and triazolo[4,5-d]-pyrimidines (8-azaguanines) are inhibitors of the enzyme purinenucleosidephosphorylase (PNPase) with Ki' values ranging from 0.05 to 1.6 microM. These compounds are enzymatically stable congeners of the potent PNPase inhibitor acyclovir diphosphate (53).
