Novel imidazoline antimicrobial scaffold that inhibits DNA replication with activity against mycobacteria and drug resistant Gram-positive cocci.

ABSTRACT: Bacterial antimicrobial resistance is an escalating public health threat, yet the current antimicrobial pipeline remains alarmingly depleted, making the development of new antimicrobials an urgent need. Here, we identify a novel, potent, imidazoline antimicrobial compound, SKI-356313, with bactericidal activity against Mycobacterium tuberculosis and Gram-positive cocci, including vancomycin-resistant Enterococcus faecium (VRE) and methicillin-resistant Staphylococcus aureus (MRSA). SKI-356313 is active in murine models of Streptococcus pneumoniae and MRSA infection and is potently bactericidal for both replicating and nonreplicating M. tuberculosis. Using a combination of genetics, whole genome sequencing, and a novel target ID approach using real time imaging of core macromolecular biosyn
