Secondary mould metabolites of Cladosporium tenuissimum, a hyperparasite of rust fungi.
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 1H and 13C NMR evidence and CD measures. Cladosporols 1-5 were active in inhibiting the urediniospore germination of the bean rust agent Uromyces appendiculatus.
