What is Aspyrone?

Plain description, key identifiers and synonyms

Aspyrone is 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. It has a role as a mycotoxin, a nematicide, an antibacterial agent and an Aspergillus metabolite. It is a polyketide, an epoxide, a secondary alcohol, a member of 2-pyranones and an antibiotic antifungal agent.

Aspyrone is an antibiotic produced by various aspergillus moulds.
