New oxazolidinones are in clinical development for the treatment of tuberculosis and nontuberculous mycobacterial (NTM) infections, as a replacement for linezolid and tedizolid, which cause mitochondrial toxicity after prolonged treatment. Here, we carried out side-by-side measurements of mitochondrial protein synthesis inhibition and activity against clinically relevant mycobacterial pathogens of approved and novel oxazolidinones. We found a large range of selectivity indices suggesting TBI-223 and sutezolid as promising candidates against tuberculosis and NTM lung disease caused by Mycobacterium kansasii.
