Nitrogen containing metabolites of Fusarium sambucinum

Niederer,Tamm,Zurcher

, p. 3997 - 4000 (1992)

2-(1-Hydroxyethyl)-quinazolin-4(3H)-one (chrysogine), 2-pyruvylaminobenzamide, 2-acetylquinazolin-4 (3H)-one and N-carbobenzoxy-L-phenylalanilol have been isolated from cultures of Fusarium sambucinum. The absolute configuration was determined by the use of the Helmchen method. 2-Acetylquinazolin-4(3H)-one is probably an artefact originating. It is doubleful whether compound is a genuine metabolite.
