Molecular heterogeneity and antiviral and interferon-inducing activities of the drug Savrats

The molecular-mass distribution of the drug Savrats has been studied by gel filtration on HW-55 f. It has been shown that the drug is heterogeneous and that the fraction with a molecular mass of 25–25 kDa exhibits a high biological activity.Mirzo Ulugbek Tashkent State University, fax (3712) 46 24 72.

Water-soluble acetylcellulose as a basis for the creation of antiviral substances and interferon inductors

Absract New derivatives of the benzene, pyridine, and pyrimidine series have been synthesized from the oxidized form of water-soluble acetylcellulose (WSAC), and their toxicity and antiviral activity have been studied in cell cultures. The presumed structure of the compounds synthesized has been investigated with the aid of physicochemical methods of analysis.Tashkent State University, fax (3712) 46 24 72.
