Adamantylthiourea derivatives as antiviral agents

Abstract

A series of nine 3-substituted 1-adamantylthioureas was prepared and tested for antiviral activity against influenza A2/Asian/J305 virus in vivo and in vitro. Protective dose 50 values were calculated for three of the compounds. One of these compounds, 7, has antiviral activity which compares favorably with that of amantadine.
