NMR‐Based Structural Elucidation of a New Dihydroisocoumarin and Related Polyketides From a Mangrove‐Derived Fusarium sp.

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Integration of bioactivity screening and LC–MS/MS metabolomics enabled the discovery of a new antibacterial dihydroisocoumarin from Fusarium sp. IQ‐1921. NMR‐based structural elucidation identified five related metabolites, with the new compound 1 showing the broadest activity against multidrug‐resistant bacteria. ABSTRACT Antimicrobial resistance (AMR)
