Abstract: New uses of hypoestoxide, its derivatives and related compounds for treatment and prevention of neurodegenerative diseases (e.g. Parkinsons disease, Alzheimers disease, Huntingtons disease) are described. More specifically, the invention relates to methods for treating various neurodegenerative diseases through administration of hypoestoxide, its derivatives and related compounds, or a combination thereof to a subject with a neurodegenerative disease such that the symptoms of the disease are treated or at least partially alleviated. Furthermore, the present invention further provides methods of preventing the development of neurodegenerative diseases in individuals who are predisposed to developing a neurodegenerative disease over time.

Abstract: Novel diterpene compounds, in particular, hypoestoxide-related compounds, are provided in pure form or as contained in the native plant source, for treatment and prophylaxis of cancer, inflammatory diseases, hyperlipidemias, malaria, and diabetes mellitus. Embodiments also pertain to methods for using the hypoestoxide-related compounds to treat various diseases and symptoms associated with those diseases.

Abstract: Methods of treating a host suffering from restenosis are provided. The methods include delivery of a stent coated with a hypoestoxide, hypoestoxide derivative or hypoestoxide agonist compound to a vessel. The methods further include the administration of a chemotherapeutic agent in combination with delivery of a stent coated with a hypoestoxide, hypoestoxide derivative or hypoestoxide agonist compound to a vessel. The chemotherapeutic agent may be coated on the stent or administered systemically.
