Current Status and Perspectives of Antibacterial Agents Belonging to 2-Oxazolidinones
Abstract
In the last three decades, 2-oxazolidinones have emerged as an important class of inhibitors of bacterial protein synthesis, effective in the treatment of multidrug-resistant (MDR) bacterial infections. From a public health perspective, the importance of 2-oxazolidinones is related to the treatment of tuberculosis (TB), primarily MDR-TB and extensively drug-resistant XDR-TB. Linezolid, the first oxazolidinone antibiotic approved by FDA, is still used in therapy despite common adverse events, such as myelosuppression and serotonergic toxicity, as well as the increasing percentage of linezolid-resistant bacteria (Staphylococcus aureus, enterococci and methicillin-resistant S. aureus). Tedizolid phosphate was the second commercially available oxazolidinone antibiotic approved, followed by other oxazolidinones (contezolid, radezolid, ranbezolid, sutezolid, delpazolid, cadazolid, TBI-233 and MK-7762) that are in clinical study. Contezolid is approved in China and cadazolid has entered phase III clinical trials. This comprehensive review intends to provide an overview of the compounds belonging to this class already in use in therapy and/or clinical studies and to portray the most significant and recent outcomes regarding new oxazolidinones under study. Three literature databases, i.e., PubMed/MEDLINE, Google Scholar and Scopus, were used for the literature search, particularly focusing on the last five years, and screened using different keywords. The design of new drugs…
