of amidate prodrugs of cyclic 9-[3-hydroxy-2-(phosphonomethoxy)propyl]adenine
(cHPMPA) featuring different amino acid motifs were synthesized. All
phosphonamidates derived from (S)-cHPMPA displayed
a broad spectrum activity against herpesviruses with EC50 values in the low nanomolar range. A phosphonobisamidate prodrug
of (S)-HPMPA also exhibited a remarkably potent antiviral
activity. In addition, the leucine ester prodrug of (S)-cHPMPA and phosphonobisamidate valine ester prodrug of (S)-HPMPA proved stable in human plasma. These data warrant
further development of cHPMPA prodrugs, especially against human cytomegalovirus
(HCMV), for which there is a high need for treatment in transplant
recipients.
