Biotransformation of squamulosone by Curvularia lunata ATCC 12017

Squamulosone (aromadendr-1(10)-en-9-one), isolated in large quantity from the plant Hyptis verticillata Jacq. (Labiatae), was incubated with the fungus Curvularia lunata ATCC 12017 in two different growth media. Six metabolites were isolated from each medium, with five of the products being common t...

Zusammenfassung:	Squamulosone (aromadendr-1(10)-en-9-one), isolated in large quantity from the plant Hyptis verticillata Jacq. (Labiatae), was incubated with the fungus Curvularia lunata ATCC 12017 in two different growth media. Six metabolites were isolated from each medium, with five of the products being common to both fermentations. All seven metabolites are novel. The insecticidal activity of these aromadendranes was evaluated against the sweet potato weevil Cylas formicarius elegantulus.
