Secondary mould metabolites of Cladosporium tenuissimum, a hyperparasite of rust fungi
摘要:
Investigation of the extracts of a culture of Cladosporium tenuissimum, a known hyperparasite of several rust fungi, gave rise to the isolation of cladosporols B-E (2-5). Their structure and stereochemistry were elucidated on the basis of H-1 and C-13 NMR evidence and CD measures.Cladosporols 1-5 were active in inhibiting the urediniospore germination of the bean rust agent Uromyces appendiculatus.
