Sutezolid (PNU-100480) is an oxazolidinone antimicrobial being developed for the treatment of tuberculosis. Target: Antibacterial Sutezolid is a much-awaited drug candidate for treatment of Mycobacterium tuberculosis. [1] Sutezolid is an oxazolidinone antibiotic currently in development as a treatment forextensively drug-resistant tuberculosis. Sutezolid is a linezolid analog with superior bactericidal activity against Mycobacterium tuberculosis in the hollow fiber, whole blood and mouse models. Like linezolid, it is unaffected by mutations conferring resistance to standard TB drugs. This study of sutezolid is its first in tuberculosis patients.[2]
