Novel pohosphonate isosteres of acyclovir (ACV) and ganciclovir (DHPG) monophosphates (20 and 32) wre foudnd to be potent and selective antiherpesvirus agents.In the series of phosphonate analogues of ACV monophosphate, only the guanine analogue 20 exhibited activity against herpesviruses, similar to the structure-activity relationship observed for base modification of ACV analogues.The phosphonate isostere of ACV monophosphate (20) was more effective than ACV in the HSV-1 infected mouse model.The 3'-carba analogues of 9-<3-hydroxy-2-(phosphonomethoxy)propyl>purines/pyrimidines (adenine, HPMPA; guanine, HPMPG; cytosine, HPMPC) are devoid of antiherpesvirus activity.This result confirms that the β-oxygen atom of the phosphonomethyl ether functionality in HPMP-purines/pyrimidines plays a critical role for activity against herpesviruses.
