Their mechanism of antimicrobial mainly bacteriostatic via inhibition of protein synthesis. Oxazolidinones are used in serious cases of bacterial infections. Their spectrum of action against a lot of microbes, which often infect humans vigorously, like penicillin and cephalosporin-resistant Streptococcus pneumonia, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci. Oxazolidinones chemical structure possesses a ring called oxazolidone, which is characterized by the S configuration of the substituent at C5, the acyl-amino-methyl group connected to C5 and the N-aryl substituent. Some oxazolidinones like linezolid were believed to have a role in COVID-19 treatment. It is also noticed that oxazolidinones have a role in improving clinical status of patients with COVID-19 and in decreasing the risk of mortality caused by co-infections. This review was conducted to discuss the chemistry, mechanism, applications and role of oxazolidinones in the treatment of COVID-19.展开更多

Stability measurements demonstrate that these compounds possess high thermostability and can endure different organic solvents as well as various acid/base solutions with pH range of 1 to 14. Importantly,compounds 1–3 can serve as high-efficiency catalysts for the transformation of CO_2 and aziridines to form high-value oxazolidinones under mild conditions, exhibiting excellent cyclicity at least five times.展开更多
