Abstract
Characterization of the antiviral properties of enisamium iodide against human respiratory viruses in in vitro experiments. In the course of experiments, the cytotoxic properties of enisamium iodide were studied against the cell lines Vero, MA-104, A549, L-41 and HEp-2. The antiviral activity of enisamium iodide was studied using virus yield reduction assay against influenza viruses, parainfluenza virus, respiratory syncytial virus, Coxsackie B3 and Coxsackie B4 viruses, as well as adenoviruses types 5 and 6. The most sensitive to the action of enisamium iodide was the human parainfluenza virus, whose activity decreased by 2.3 orders of magnitude under the action of the drug in A549 cells. Of the cell cultures used, enisamium iodide exhibited the maximum antiviral effect in human lung carcinoma cells A549, where, in its presence, the level of reproduction of adenoviruses of types 5 and 6, Coxsackie viruses B3 and B4, and human parainfluenza virus decreased by an order of magnitude or more. The antiviral activity of enisamium iodide was least manifested in Vero cells. According to the results of in vitro experiments, enisamium iodide can be considered as an antiviral drug with a wide spectrum of activity against human respiratory viruses.
