title: [In vitro antiviral activity of fullerene amino acid derivatives in cytomegalovirus infection].
abstract: The in vitro effect of 5 water soluble fullerene C60 amino acid derivatives (FAD) on the development of cytomegalovirus infection was studied in the schemes of the therapeutic, prophylactic and virucidal action. The following compounds as FAD were used: fullerene conjugated with Na salt of gamma-aminobutyric acid (C60-ABA-Na), 2 derivatives based on Na salts of fullerene-gamma-aminobutyric acid and fullerene-omega-caproic acid (C60-ABA-OH-Na and C60-ACA-OH-Na respectively) and 2 derivatives based on methyl ethers of the above mentioned fullerene amino acids (C60-ABA-OH-CH3 and C60-ACA-OH-CH3). All the FAD were able to inhibit the development of the virus cytopathogenic action in the cell culture. However, the compounds had different antiviral properties. C60-ABA-OH-Na, C60-ABA-CH3 and C60-ACA-CH3 showed marked antiviral activity in the prophylactic scheme. 50-Percent inhibition of the virus cytopathogenic action (ID50) was observed when concentrations of the compounds were 0.31, 5 and 25 mcg/ml respectively. C60-ACA-OH-Na inhibited the development of cytomegalovirus infection in the cell culture only in the scheme of the therapeutic action (ID50 4 mcg/ml). C60-ABA-Na had the highest antiviral effect. In a concentration of 0.22 mcg/ml it inhibited the cytomegalovirus plague-forming capacity by 50% in both the prophylactic and the virucidal schemes. The chemotherapeutic index of the compound was within the limits of 2500 to 5450.
