Studying the Effect of Amino Acid Substitutions in the M2 Ion Channel of the Influenza Virus on the Antiviral Activity of the Aminoadamantane Derivative and .

The aminoadamantane derivative of L-histidyl-1-adamantayl ethylamine hydrochloride (HCl*H-His-Rim) has showed a high inhibition level against influenza A virus strains . The aim of this work is to search and establish evidence of the direct effect of the drug on influenza A virus proton channel M2. The compound HCl*H-His-Rim was obtained by classical peptide synthesis methods.

[Adamantan derivatives capable of inhibiting the reproduction of a Rimantadine resistant strain of influenza A(H1N1)pdm09 virus (Influenza A virus, Alphainfluenzavirus, Orthomyxoviridae).].

Introduction: Adamantanthane-type drugs such as rimantadine and amantadine have long been used to treat diseases caused by influenza A virus. However, as a result of the mutations, influenza viruses have become resistant to aminoadamantans. The target for these drugs was the protein channel M2.

[Assessment of the antiviral activity of 2HCl*H-His-Rim compound compared to the anti-influenza drug Arbidol for influenza caused by A/duck/Novosibirsk/56/05 (H5N1) (Influenza A virus, Alphainfluenzavirus, Orthomyxoviridae).].

Introduction: The emergence of influenza virus strains with drug resistance to antiviral drugs requires finding new compounds, potential direct-acting inhibitors. Аdamantane compounds drugs used since the 1960s have lost their activity the resulting due to resistance. Only neuraminidase inhibitors such as zanamivir and oseltamivir have been approved by WHO for influenza treatment.
