Abstract
Schizophyllum commune is a causative fungus of human mycosis. Its metabolites produced at 27 °C were compared with those produced at 37 °C, to obtain a candidate low-molecular-weight virulence factor related to the pathogenicity of this fungus. We found that S. commune specifically produces two acyclic terpene mannosides at 37 °C. They were identified as nerolidol β-d-mannoside (1) and geranylnerol β-d-mannoside (2) by NMR, MS, and CD analyses. Compound 2, a new compound named mannogeranylnerol, showed weak antibiotic activity that was slightly stronger than that of compound 1.
