Details of the Technology Offer

The present invention provides an amphiphilic small-molecule with bactericidal and fungicidal activity. The compound is synthesized in scalable conditions from readily available and low-cost building blocks. The molecule shows significant biocidal activity against multidrug-resistant bacteria, including the ESKAPE pathogens, and fungi. Notably, the compound acts synergistically with amphotericin B and fluconazole against the reference Candida albicans strain. Significant dose-dependent disruption of bacterial membranes is observed upon treatment with the new cationic steroid. Polymeric coatings containing up to 1.5 % w/v cationic steroid sustain effective reduction of the formation of E. coli biofilms in ureteral stents, in relevant hydrodynamic conditions.
