Derivatives of rupestonic acid (5a–e) were synthesized and evaluated preliminarily at the National Center for Drug Screening (PRC) for antiviral activity against type A3 and B flu virus and HSV-I and HSV-II in order to improve the biological activity of rupestonic acid. It was found that compound 5b was more active than rupestonic acid against type A3 flu virus.
