What is Asperlactone?

Plain description, key identifiers and synonyms

Asperlactone is a member of the class of butenolides that is furan-2(5H)-one substituted by (2S,3S)-3-methyloxiran-2-yl and (1S)-1-hydroxyethyl group at positions 3 and 5R, respectively. It is a secondary metabolite isolated from Aspergillus ochraceus that exhibits antifungal and antibacterial properties. It has a role as an insect growth regulator, a mycotoxin, an antibacterial agent and an Aspergillus metabolite. It is a polyketide, an epoxide, a secondary alcohol, a butenolide and an antibiotic antifungal agent.

Asperlactone is a biologically active polyketide metabolite produced mainly from aspergillus.
