Definition:A member of the class of 2-pyranones that is 5,6-dihydro-2H-pyran-2-one in which the hydrogens at positions 3, 5S and 6R are replaced by (2S,3S)-3-methyloxiran-2-yl, hydroxy and methyl groups, respectively. It is a fungal metabolite isolated from Aspergillus melleus and exhibits nematicidal, antibacterial and antifungal properties.
Synonyms:exact_synonym: (5S,6R)-5-hydroxy-6-methyl-3-[(2S,3S)-3-methyloxiran-2-yl]-5,6-dihydro-2H-pyran-2-one
