A novel secondary metabolite from the Eucalyptus pathogen Mycosphaerella cryptica / G. Assante, G. Nasini, S. Zhang, R.E. Bradshaw. - In: FOREST PATHOLOGY. - ISSN 1437-4781. - 39:5(2009), pp. 289-292. [10.1111/j.1439-0329.2008.00582.x]
Abstract:
The most abundant metabolite of the eucalyptus leaf spot pathogen Mycosphaerella cryptica was
extracted from agar cultures. The structure of the compound was elucidated by detailed studies of
NMR and MS data and by comparison with derivatives. The compound is a previously undescribed
diphenylether structurally related to pannaric acid found in lichens. Culture extracts from another
species of Mycosphaerella isolated from the same environment yielded 5-hydroxymethylfuran-
3-carboxylic acid, a furan acidic compound previously isolated from a basidiomycete fungus. Assays
for bioactivity of these metabolites revealed no evidence for antimicrobial activity. Some phytotoxicity
was seen on newly emerged leaves of Eucalyptus globulus, but not on juvenile or adult leaves, when
treated with either metabolite.
