Secondary phytotoxic metabolites from pathogenic fungi: Structure, synthesis and activity

Abstract

The secondary metabolites from three pathogenic fungii, Eutypa lata, Ceratocistis fimbriata var. coffea and Ceratocistis fimbriata var. platani, responsible respectively for the vine (Vitis vinifera ), coffee tree (Coffea sp). and plane tree (Platanus acerifolia and P. orientalis,) diseases have been investigate. Eutypine (1) and other substituted phenylacetylenic compounds (2–2) have shown a strong phytotoxic activity on the vine.The isocourmarins (12–16) seemed to play an important role into the canker diseases. The resistance factors to Botrytis cinera in grapevine have also been studied and six phenolic derivatives (22–28) that inhibiting stilbene oxydase have been isolated. © 1994 IUPAC
