Polymyxins slow down lateral diffusion of proteins and lipopolysaccharide in the E. coli outer membrane [PDF]
Communications BiologyPolymyxins are often administered as last resort antibiotics for Gram-negative bacterial infections. However, given unwanted side-effects, efficacy and recent reports of resistance against polymyxins, there is an urgency to develop alternatives.

Polypeptide Self-Assembled Nanoparticles as Delivery Systems for Polymyxins B and E
Pharmaceutics, 2020 Polymyxins are peptide antibiotics that are highly efficient against many multidrug resistant pathogens. However, the poor stability of polymyxins in the bloodstream requires the administration of high drug doses that, in turn, can lead to polymyxin ...

Next-Generation Polymyxin Class of Antibiotics: A Ray of Hope Illuminating a Dark Road
Antibiotics, 2022 Although new-generation antimicrobials, in particular β-lactam/β-lactamase inhibitors, have largely replaced polymyxins in carbapenem-resistant Gram-negative bacterial infections, polymyxins are still needed for carbapanem-resistant Acinetobacter ...
