title: The chloroxoquinolinic derivative 6-chloro-1,4-dihydro-4-oxo-1-(beta-D-ribofuranosyl) quinoline-3-carboxylic acid inhibits HSV-1 adsorption by impairing its adsorption on HVEM.
abstract: In this paper, we describe that the oxoquinolinic acid derivative (compound A) inhibited HSV-1 adsorption on Vero cells. This effect was achieved with an EC(50) value of 10 +/- 2.0 microM and with low cytotoxicity, since the CC(50) value for compound A was >1000 microM. Moreover, we demonstrate for the first time that adsorption inhibition was due to the blockage of the interactions between HSV-1 and the cellular receptor herpes virus entry mediator (HVEM). These results show that compound A can prevent HSV-1 infection in Vero cells, encouraging further studies to determine at what level compound A inhibits HSV-1-HVEM interactions.
