Abstrakt: 2,4-Dihydro-4-(β-d-ribofuranosyl)-1,2,4(3H)-triazol-3-one (2) was identified as the principal phytotoxic component of a fermentation broth derived from an Actinomadura. The compound is a new natural product, but known by synthesis. Broad-spectrum herbicidal activity was demonstrated in greenhouse tests. Metabolite reversal studies suggested the target site was adenylosuccinate synthetase, which was confirmed by direct measurement of the activity of the 5‘-phosphorylated derivative on the isolated enzyme.
