Abstract

Unlike amantadine (1-adamantanamine), tromantadine (N-1-adamantyl-N-[2-(dimethyl amino)ethoxy]acetamide hydrochloride) inhibits herpes simplex virus type 1 (KOS strain)-induced cytopathic effect and virus replication with limited toxicity to the cells. Vero and HEp-2 cells tolerated up to 2 mg of tromantadine per 2 X 10(6) cells for 24-, 48-, or 96-h incubation periods with little change in cell morphology. Treatment of the cells with 10 to 50 micrograms of tromantadine reduced herpes simplex virus-induced cytopathic effect. Treatment with 100 to 500 micrograms of tromantadine inhibited herpes simplex virus-induced cytopathic effect and reduced virus production. Complete inhibition of virus production was observed with treatments of 500 micrograms to 1 mg. The antiherpetic activity of tromantadine was dependent upon the viral inoculum size and the time of addition of the compound with respect to infection. Virion synthesis and viral polypeptide synthesis were inhibited by addition of tromantadine at the time of infection or 4 h postinfection. The results are consistent with tromantadine inhibition of an early event in herpes simplex virus infection, before macromolecular synthesis, and a late event, such as assembly or release of virus.
