Xanthones as Potential Antioxidants

Current Medicinal Chemistry, 2013
Xanthones (dibenzo-γ-pyrones) constitutes an important class of oxygenated heterocycles and occur as secondary metabolites in plants and microorganisms. They are known for various biological activities such as antioxidant, monoamine oxidase inhibitor, antihypertensive, hepatoprotective, antithrombotic, antifungal and anticancer.
