Strobilurin M, Tetrachloropyrocatechol and Tetrachloropyrocatechol Methyl Ether:

New Antibiotics from a Mycena Species

Abstract

The antifungal and cytostatic compound strobilurin M (1) is a new variant of the strobilurins produced by Mycena sp. 96097, a tropical basidiomycete. The same fungus was found to produce tetrachloropyrocatechol (3a) and tetrachloropyrocatechol methyl ether (3b), new natural products, which exhibit antifungal, antibacterial and cytotoxic activities.
