Influence of hyperthermia on experimental viral infections in vitro

The effects of hyperthermia (39 and 41 C) on virus multiplication in vitro (HSV-1, VSV on Vero cells and EMC on L929 cells) have been explored. The cells were infected with HSV-1, VSV or EMC viruses and heated to 39 or 41 C before, during or after the viral infection. The titer of the virus show that temperature of 41 C acts as an inhibitory agent on HSV-1 and VSV virus replication in Vero cells.

Structural basis for antiviral activity of flavonoids-naturally occurring compounds

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.

Tuftsin a natural peptide with antiviral activity--structural basis of its action

The influence of tuftsin--the natural phagocytosis stimulating tetrapeptide and its elongated analogues--on the mortality of encephalomyocarditis virus-infected NMRI mice was investigated. It seems that amino acids elongation in the parent peptide chain does not result in significant increase of antiviral activity of the compounds tested.
