摘要:This invention relates to the polymeric salts of 3.5-dimethyl-1-adamantylammonium and carboxylated (co)polymers, as well as to the use of produced salts as antiviral agents. Object of the invention is the synthesis of new salts of 3.5-dimethyl-1-adamantylammonium and carboxylated (co)polymers, identification of the compounds with antiviral activity and durable action among them. The task is solved by the synthesis of salts of 3.5-dimethyl-1-adamantylammonium and water-soluble carboxylated (co)polymers of a general formula (1): nwhere m and n are mol%, m = 100 - n, nand carboxylated (co)polymers are selected from the group: nvinylaminosuccinic acid, a copolymer of vinyl alcohol and N-vinylaminosuccinic acid, a copolymer of N-vinylpyrrolidone and N-vinylaminosuccinic acid, copolymer of N-vinylpyrrolidone and crotonic acid; copolymer of N-vinylaminosuccinimide and maleic anhydride; copolymer of N-vinylpyrrolidone and maleic anhydride; polyacrylic acid A general synthesis method and synthesis examples are given for each of claimed compounds, as well as the results of identification of toxicity and comparative antiviral activity. Produced compounds are expressly identified by methods of IR analysis, elements analysis, and potentiometric titration, have quite high antiviral activity against the viruses of influenza types A and B, at that they feature durable (prolonged) action which allows using these produced salts not only as antiviral medications for sparing treatment but for prevention of viral diseases.
