Botryorhodines K (1) and L (2), two new depsidone derivatives, along with one known metabolite, 4-O-demethylbarbatic acid (3), were isolated from the culture extract of a fungus of the genus Arcopilus. The structures of 1‒3 were determined by the analysis of NMR and MS spectral data and the absolute configuration of 1 was established by single-crystal X-ray diffraction analysis. Compounds 1 and 2 showed antimicrobial activity against Gram-positive bacteria and cytotoxicity against murine leukemia P388 cells.
