      In this paper, we present novel bioactivity for barettin isolated from the marine sponge Geodia barretti. We found that barettin showed strong antioxidant activity in biochemical assays as well as in a lipid peroxidation cell assay. A de-brominated synthetic analogue of barettin did not show the same activity in the antioxidant cell assay, indicating that bromine is important for cellular activity. ...

    • NMR Backbone Assignment of VIM-2 and Identification of the Active Enantiomer of a Potential Inhibitor

      Carbapenem resistance caused by metallo-β-lactamases is a serious global challenge that, if not tackled efficiently, is expected to lead to millions of deaths in the coming decades. Verona-integron encoded metallo-β-lactamase 2 (VIM-2) is a bacterial enzyme that has been reported from multidrug-resistant nosocomial isolates of Pseudomonas aeruginosa and other Gram-negative pathogens. As it hydrolyzes ...
