title: Design, synthesis, and structure-activity relationship studies of new phenolic DNA gyrase inhibitors.
abstract: Starting from a biased needle screening hit 3a, we report herein the design and synthesis of a series of novel 2,3-dihydroisoindol-1-ones structurally related to cyclothialidine 2 with DNA gyrase inhibitory activity. In this series, some compounds exhibited promising antibacterial activity against gram-positive bacterial strains.
