Challenge
Infections with bacteria that are resistant to conventional antibiotics are increasing. Alternative antibiotics to overcome such resistances.
Technology
A series of novel Re(I)(CO)3–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 on 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.
Commercial Opportunity
The technology is offered for licensing and further therapeutic development.
Development Status
Compounds have been tested against Gram-positive bacteria.
Patent Situation
German priority application has been filed on July 7, 2017.
