AB  - Gram-negative 'superbugs' such as New Delhi metallo-beta-lactamase-1 (blaNDM-1) 
      producing pathogens have become world's major public health threats. Development 
      of molecular strategies that can rehabilitate the 'old antibiotics' and halt the 
      antibiotic resistance is a promising approach to target them. We report 
      membrane-active macromolecules (MAMs)that restore the antibacterial efficacy 
      (enhancement by >80-1250 fold) of tetracycline antibiotics towards blaNDM-1 
      Klebsiella pneumonia and blaNDM-1 Escherichia coli clinical isolates.Organismic 
      studies showed that bacteria had an increased and faster uptake of tetracyclinein 
      the presence of MAMs which is attributed to the mechanism of re-sensitization. 
      Moreover,bacteria did not develop resistance to MAMs and MAMs stalled the 
      development of bacterial resistance to tetracycline. MAMs displayed 
      membrane-active properties such as dissipation of membrane potential and 
      membrane-permeabilization that enabled higher uptake of tetracycline in bacteria. 
      In-vivo toxicity studies displayed good safety profiles and preliminary in-vivo 
      antibacterial efficacy studies showed that mice treated with MAMs in combination 
      with antibiotics had significantly decreased bacterial burden compared to the 
      untreated mice. This report of re-instating the efficacy of the antibiotics 
      towards blaNDM-1 pathogens using membrane-active molecules advocates their 
      potential for synergistic co-delivery of antibiotics to combat Gram-negative 
      superbugs.
