Evaluation of antiviral activity of terpenophenols and some of their N- and O-derivatives.

A comparative evaluation of the antiviral activity of a number of new and previously synthesized terpenophenols and their N- or O-containing derivatives against the A/Puerto Rico/8/34 (H1N1) virus strain was carried out. 2-Isobornylphenol, 1,2-dihydroxy-6-isobornyl-4-methylbenzene, 2-isobornyl-1,4-benzoquinone, and N-butyl-4-hydroxy-3,5-diisobornylbenzamide showed the highest activity.
