Two unusual polyketide-sesquiterpene metabolites, craterodoratins T () and U (), along with the known compound craterellin A (), were isolated from the higher fungus . The structures of isolated compounds were characterized based on nuclear magnetic resonance (NMR) and mass spectrum (MS) spectroscopic analysis, while the absolute configuration of the compounds was determined by theoretical NMR and electronic circular dichroism (ECD) calculations. Compound possessed a rare structure with two aromatic groups. Compounds and showed immunosuppressive activity with IC values ranging from 5.516 to 19.953 M.
