Specific inhibition of glyceraldehyde-3-phosphate dehydrogenase by koningic acid (Heptelidic acid).

Abstract
A sesquiterpene named koningic acid has been isolated from a strain of Trichoderma koningii as a potent inhibitor of ATP generation in the glycolytic pathway. From experiments with both cultured mouse carcinoma FM3A cells and isolated enzymes, it was shown that koningic acid is a specific inhibitor of glyceraldehyde 3-phosphate dehydrogenase that catalyzes the conversion of glyceraldehyde 3-phosphate to 3-phosphoglycerate.
