Tulasnein and podospirone from the coprophilous xylariaceous fungus Podosordaria tulasnei

• Tulasnein (1), a new metabolite with strong antimicrobial and weaker cytotoxic and phytotoxic activity, was isolated from culture filtrates of three strains of the xylariaceous coprophilous fungus Podosordaria tulasnei. The producing strains were identified by their rhizomorphs and by ITS rDNA sequence analysis. A second new metabolite, podospirone (2), was also produced by all three strains whereas the weakly cytotoxic (+)-3,4-anhydroshikimic acid methyl ester (3) was detected in only one strain.
