Virtual Screening Approach and Investigation of Structure-Activity Relationships To Discover Novel Bacterial Topoisomerase Inhibitors Targeting Gram-Positive and Gram-Negative Pathogens.
J.Med.Chem., 62:7445-7472, 2019

PubMed Abstract: Bacterial resistance is increasing rapidly, requiring urgent identification of new antibacterial drugs that are effective against multidrug-resistant pathogens. Novel bacterial topoisomerase inhibitors (NBTIs) provide a new strategy for investigating the well-validated DNA gyrase and topoisomerase IV targets while preventing cross-resistance issues. On this basis, starting from a virtual screening campaign and subsequent structure-based hit optimization guided by X-ray studies, a novel class of piperazine-like NBTIs with outstanding enzymatic activity against and DNA gyrase and topoisomerase IV was identified. Notably, compounds , , and with potent and balanced multitarget enzymatic profiles exhibited excellent efficacy against selected Gram-positive and Gram-negative pathogens, as well as clinically relevant resistant strains. Overall, the new NBTI chemotype described herein, owing to the broad-spectrum antibacterial activity and favorable in vitro safety profile, might serve as a basis for the development of novel treatments against serious infections.
