Metabolites from Eutypa species that are pathogens on grapes.

Structural and synthetic studies of the metabolites isolated from Eutypa lata are reviewed. This fungus is the causative agent of Eutypa dieback disease, also known as eutyposis or dying-arm disease, a perennial canker that affects grapevines and many other woody fruit plants. The review, which encompasses all the literature in this field up to the present and in which 76 references are cited, also includes a detailed study of the biological activity of the metabolites, especially the role of toxins in the development of the plant disease. Some aspects of the synthesis and biosynthesis of these metabolites and related compounds are discussed.
