Oxazolidinone antibiotics

Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug-resistant tuberculosis. It is used either by injection into a vein or by mouth.

Tedizolid, sold under the brand name Sivextro (by Merck) is an oxazolidinone-class antibiotic. Tedizolid phosphate is a phosphate ester prodrug of the active compound tedizolid. It was developed by Cubist Pharmaceuticals, following acquisition of Trius Therapeutics (originator: Dong-A Pharmaceuticals), and is marketed for the treatment of acute bacterial skin and skin structure infections (also known as complicated skin and skin-structure infections (cSSSIs)).

Eperezolid is an oxazolidinone antibiotic.

Sutezolid is an investigational new drug that is being evaluated for the treatment of extensively drug-resistant tuberculosis. It differs from linezolid by replacement of the morpholine oxygen with a sulfur atom. Like linezolid, sutezolid is a bacterial protein synthesis inhibitor. In preclinical studies, sutezolid demonstrated superior antituberculosis activity compared to linezolid.

Ranbezolid (RBx7644) is an oxazolidinone antibacterial. It competitively inhibits monoamine oxidase-A (MAO-A).

Posizolid is an oxazolidinone antibiotic under investigation by AstraZeneca for the treatment of bacterial infections. At a concentration of 2 mg/L it inhibited 98% of all Gram-positive bacteria tested in vitro.

Radezolid (INN, codenamed RX-1741) is a novel oxazolidinone antibiotic being developed by Melinta Therapeutics, Inc. for the treatment of bacterial acne.
