Immunomodulatory Activity and Influence on Mitotic Divisions ofN-Benzoylphenylisoserinates ofLactariusSesquiterpenoid Alcoholsin vitro

Autor: Dariusz Kawecki, Maria Nowaczyk, Monika Kniotek, Ewa Krawczyk, Mirosław Łuczak, Anna Majewska

Publikováno v: Planta Medica. 71:819-824

Six N-benzoylphenylisoserinates of Lactarius sesquiterpenoid alcohols, which previously showed antiviral activities, were tested for their biological properties. Their influence on the mitotic division of the cells and on selected immunological param
