Tropolone emerged from the screening of a chelator fragment library (CFL) as an inhibitor of the Zn(2+)-dependent virulence factor, Pseudomonas aeruginosa elastase (LasB). Based on this initial hit, a series of substituted tropolone-based LasB inhibitors was prepared, and a compound

Phaeobacter gallaeciensis, a member of the abundant marine Roseobacter clade, is known to be an effective colonizer of biotic and abiotic marine surfaces. Production of the antibiotic tropodithietic acid (TDA) makes P. gallaeciensis a strong antagonist of many bacteria, including

To screen biocontrol agents against Burkholderia plantarii, the causative agent of rice seedling blight, we employed catechol, an analog of the virulence factor tropolone, to obtain chemical stress-resistant microorganisms. The fungal isolate PS1-7, identified as a strain of Trichoderma virens

6-Hydroxymethyl-6-methylcyclohexa-2,4-dienone is a mechanistic probe which when incubated with an extradiol dioxygenase yields a 2-tropolone product. This observation was originally interpreted as evidence supporting a direct heterolytic 1,2-alkenyl migration mechanism for a ring expansion reaction catalyzed by this class of

A gene cluster encoding the biosynthesis of the fungal tropolone stipitatic acid was discovered in Talaromyces stipitatus (Penicillium stipitatum) and investigated by targeted gene knockout. A minimum of three genes are required to form the tropolone nucleus: tropA encodes a
