Pyrazolopyrimidines and pyrazolotriazines with potent activity against herpesviruses

Synthesis of several pyrazolo[1,5-c]pyrimidines, pyrazolo[1,5-a]pyrimidines and pyrazolo[1,5-a][1,3,5]triazines with potent activity against herpes simplex viruses is described. Synthetic approaches allowing for variation of the substitution pattern are outlined and resulting changes in antiviral activity are highlighted. Several compounds with in vitro antiviral activity similar or better than acyclovir are described.
