The effect of different substituents of quercetin and luteolin on the ability to inhibit the herpes simplex virus (HSV-1) replication in RK-13 cells was studied. It seems that parent compounds with free hydroxyl groups at C-5, C-7, C-3', C-4' and additionally at C-3 have the highest activity. Substitution of those groups caused decrease of or completely abolished the antiviral activity of the tested compounds.
