[New properties of trental as an inhibitor of viral activity with a wide range of activity].

Experimental investigations on the spectrum and degree of the expression of trental antiviral activity were carried out. The investigations were done in cell cultures and laboratory animals using laboratory strains (including drug-resistant ones) of 13 viruses, causative agents of human and animal infections. The drug demonstrated its activity against 8 viruses of 7 families.

[Compounds, similar to acyclovir. VIII. Synthesis and antiviral activity of (R/S)-5-hydroxy-4-hydroxymethyl-3-oxapent-2-yl derivatives of nucleic bases].

The (R/S)-5-hydroxy-4-hydroxymethyl-3-oxapent-2-yl derivatives of the uracil, thymidine, cytosine, adenine, guanine and 1,2,4-triazol-3-carboxamide were synthesized using 1,3-diacetoxy-2-(1-acetoxy)propane and 1,3-dichloro-2-(1-chlorethoxy)propane as alkylating agents. The guanine derivatives exhibited activity against HSV-1 (chemotherapeutic index 32).

[Antiviral properties of various pharmacologic groups of drugs].

Currently used cardiovascular drugs such as nicotinamide, strophanthin, corglycon, curantyl, cavinton, papaverin hydrochloride, nicotinic acid, xantinole nicotinate, isoptin, parmidin and halidor were studied by the program of antiviral drug screening. The majority of them (9 out of 11) were shown to have antiviral activity which was rather individual by its specificity and level. Laboratory strains of 9 viruses inducing the most common infections in man and animals, i.

[Lipid metabolism in experimental virus infections].

The effect of herpes simplex virus (HSV) and influenza virus (IV) on lipid metabolism was studied. In conditions of acute herpetic infection of rabbits we detected typical dyslipidemia, characterized by increased contents of total cholesterol, beta-cholesterol and triglycerides in the absence of trustworthy differences in concentrations of alpha-cholesterol. The use of antiherpetic preparation furavir, on the background of infection, corrected lipid spectrum of the infected animals.
