abstract:
A new antifungal 6-substituted 2H-pyran-2-one, named viridepyronone, has been isolated from a
cultural filtrate of a strain of Trichoderma viride showing antagonistic activity in vitro toward Sclerotium
rolfsii, which is the causal agent of crown and stem rot of artichoke. Viridepyronone was characterized
as 6-(4-oxopentyl)-2H-pyran-2-one 2 with spectroscopic methods. Bioassays showed that viridepyronone
had a good antifungal activity against S. rolfsii, and its minimum inhibitory concentration (over
90% inhibition) was found to be 196 íg/mL. This is the first report of viridepyronone produced by any
species of fungi.
