Description
Summary:The prospect of ever increasing antibiotic resistance eroding currently available treatment options for bacterial infections underscores the need to continue to identify new antibiotics, preferably those that act on novel targets or with novel mechanisms of action. Bacterial gyrase B subunit (GyrB), an essential component of bacterial gyrase required for successful DNA replication, represents such a target. We describe recent examples of GyrB inhibitors and point out their potential utility for treatment of mycobacterial diseases caused by (TB) and non-tuberculous mycobacteria (NTM). Current therapeutic options for these diseases are often suboptimal due to resistance to current standard of care antibiotics. A future GyrB inhibitor-based antibiotic could offer a new and effective addition to the armamentarium for treatment of mycobacterial diseases and possibly for infections caused by other bacterial pathogens. One GyrB inhibitor, SPR720, has recently completed a first-in-human clinical trial and is in clinical development for the treatment of NTM and TB infections.
