PG - 161-74 AB - Methoxymethyldeoxyuridine-5'-monophosphate (MMUdR-MP) and arabinofuranosyladenine-5'-monophosphate (Ara-AMP) had significant antiviral activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in RK-13 and Vero cells. MMUdR-MP and Ara-AMP were more potent than methoxymethyldeoxyuridine (MMUdR) and arabinofuranosyladenine (Ara-A) against the MS strain of HSV-2. MMUdR-MP inhibited replication of HSV-1r (mutant resistant to MMUdR). MMUdR in combination with Ara-AMP showed additive activity; whereas the MMUdR-MP and Ara-AMP combination was antagonistic against herpes viruses. MMUdR in combination with Ara-A was synergistic in reducing the log virus yield. Cytotoxicity (microscopic lesions) was observed on exposure to MMUdR-MP and Ara-AMP at 450 and 90 microM, respectively. Rapidly proliferating RK-13 cells exposed to Ara-AMP (64 microM) were killed. In the same system, the cells surviving after incubation with MMUdR-MP (650 microM), multiplied at an almost normal rate.
