EF-Tu-binding Re-complexed antibiotics - Re-complexed compounds targeting the elongation factor EF-Tu

pdf

Ref.-Nr. 5200

A series of novel Re(I)-(CO)3-N-heterocyclic carbene (NHC) complexes bearing unsubstituted benzimidazol-2-ylidene ligands as well as a variety of bisimine ligands has been prepared and comprehensively characterised. The complexes were found to exhibit potent antimicrobial activity against gram-positive bacterial strains in the low micromolar concentration range, rendering these compounds interesting lead structures for the development of novel metal-based antibiotic agents.

Keywords: Antibiotika, Bakterien, Infektion, gram-positiv, antibiotics, bacteria, infection, Gram-positive

Anti-Gram-positive activity:
Substances have good activity against Bacillus subtilis and Staphylococcus aureus. Activity against MRSA strains were in the low and sub-micromolar range. No anti-Gram-negative activity was observed.

EF-Tu was identified as target in pull-down experiments using biotinylated compound. Protein biosynthesis inhibition was detected in precursor incorporation experiments using unlabeled compound.

Validated target:
Protein biosynthesis inhibition was observed and EF-Tu identified as target protein. Protein biosynthesis is a clinically validated target. Comparative proteomics studies suggest that the mechanism of action is different from known EF-Tu inhibitors.


Commercial Opportunities

The technology is offered for licensing and further therapeutic development.

Competitive Advantages

  • Novel antibiotic class
  • Activity against Gram-positive bacteria
  • Inhibits translation – a validated target
