Abstract
The isolation and structure elucidation of collimonins A-D (1-4) from the fungus-feeding bacterium Collimonas fungivorans Ter331 are reported. Collimonins are new derivatives of polyoxygenated hexadecanoic acid, including an ene-triyne moiety. Their absolute configurations were fully determined by combining spectroscopic, chemical, and crystalline sponge methods. Collimonins showed antifungal or pigmentation activities against the fungus Aspergillus niger ATCC 9029.
