Therapies Development Targeting β-Lactamases of Enterobacterales

In the battle against antibiotic resistance, the development of therapies targeting β-lactamases of Enterobacterales is of paramount importance. By utilizing enzyme inhibitors, β-lactamase-resistant antibiotics, and combination therapies, we can overcome the challenges posed by these highly adaptable enzymes. Ace Therapeutics is committed to pushing the boundaries of scientific innovation and delivering novel solutions to combat antibiotic resistance.

Introduction to β-Lactamases of Enterobacterales

Enterobacterales possess a wide array of β-lactamases, classified into different groups based on their molecular structures and substrate profiles. The most clinically relevant β-lactamase groups include the extended-spectrum β-lactamases (ESBLs), AmpC cephalosporinases, and carbapenemases. Each group exhibits unique characteristics, making them challenging targets for therapeutic intervention.

Various Therapies Targeting β-Lactamases of Enterobacterales

  • Enzyme inhibitors. These inhibitors act by binding to the β-lactamase enzyme, preventing it from hydrolyzing β-lactam antibiotics. By combining an inhibitor with a β-lactam antibiotic, the efficacy of the antibiotic can be restored.
  • β-lactamase-resistant antibiotics. An intriguing and innovative strategy emerges - the development of β-lactam antibiotics endowed with structural modifications that confer formidable resistance against the hydrolytic actions of these enzymes.
  • Combination therapies. Combining different antibiotics or antibiotic classes has been an effective strategy to combat β-lactamase-mediated resistance. By utilizing multiple drugs with distinct mechanisms of action, the likelihood of bacterial resistance can be minimized.
