Hybridization of antimicrobial oxazolidinones with commercial drugs: A fight against the "superbugs".

Abstract

Antimicrobial resistance caused by the emergence of antibiotic-resistant microbes, termed as "superbugs," poses a grave healthcare concern in the contemporary era. Though this phenomenon is natural, an incessant use of antibiotics due to their unregulated over-the-counter availability, and a lack of compliance with the legislation seem to be major contributing factors. This phenomenon has further complicated the treatment of common infectious diseases thereby leading to prolonged illness, disability, and even death. In addition, a sizeable impact on the healthcare cost is met due to a prolonged stay at the medical facilities to receive an intensive care. Overall, the gains of "Millennium Development Goals" and the accomplishment of Sustainable Development Goals are at risk due to the emerging antimicrobial resistance. Since an early identification and development of novel antibiotic classes that evade antimicrobial resistance appears improbable, the strategy of hybridization of the existing antibiotics with efficacious pharmacophores and drug molecules with a different mechanism of antimicrobial action can be a silver lining for the management of superbugs. In this regard, we aim to provide a perspective for the applicability of the hybridization of oxazolidinone class of antibiotics with other drugs for evading antimicrobial resistance.
