Antibiotics from basidiomycetes. XXXIII. Oudemansin X, a new antifungal E-.BETA.-methoxyacrylate from Oudemansiella radicata (Relhan ex Fr.) Sing.

Abstract

In a search for new natural variants of strobilurins and oudemansins we detected oudemansin X in the culture broth of Oudemansiella radicata. The same fungus was also found to produce strobilurin A. The isolation, structure determination, and biological evaluation of oudemansin X will be described in the following.
