Dual-acting hybrid antibiotics: a promising strategy to combat bacterial resistance

Abstract

The approach of dual-acting hybrid antibiotics holds significant current promise in overcoming existing resistance mechanisms, as three of such compounds are entering clinical trials. However, the key challenge in this area should be a broader experimental demonstration of whether the "synergistic effect" or the "antagonistic effect" of the developed hybrid drug is better at preventing/reducing the evolution of resistance. This fundamental challenge must be overcome before yielding a successful drug.
