Two new compounds from cultures of the basidiomycete Daedaleopsis tricolor.

Two new compounds, daedatrin K (1) and 2-hydroxy-1-(5-(hydroxymethyl)furan-2-yl)propan-1-one (2), were isolated from cultures of the basidiomycetes Daedaleopsis tricolor. The new structures were elucidated on the basis of extensive spectroscopic methods. At the same time, two compounds were tested for their cytotoxicities against five human cancer cell lines.
