Abstract
A new decalin, decatamariic acid, was isolated from a cultured broth of the fungus Aspergillus tamarii FKI-6817. Its absolute configuration was elucidated by NMR and electronic circular dichroism. Decatamariic acid (10 μM) elicited ~50% inhibition of the ATP production in mitochondria isolated from wild-type Saccharomyces cerevisiae without affecting the activities of respiratory enzymes. The action manner of this compound may be interesting as a possible seed for new pesticides.
