title: Structure and semisynthesis of platensimide A, produced by Streptomyces platensis.
abstract: Platensimycin and platencin are novel natural product antibiotics that inhibit bacterial growth by inhibiting condensing enzymes FabF and FabF/FabH of fatty acid biosynthesis pathways, respectively. Continued search for the natural congeners of these compounds led to the isolation of platensic acid, the free C-17 tetracyclic enoic acid, and platensimide A, a 2,4-diaminobutyric acid amide derivative. Isolation, structure, semisynthesis, and activity of these compounds are described.
