WARF: P140321US02

New Broad-Spectrum Antibiotics


INVENTORS -

Douglas Weibel, Katherine Hurley, Katherine Faulkner

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing small molecule compounds that interfere with bacterial membranes.
OVERVIEWThe rise of antibiotic-resistant bacteria represents a potential health crisis. Some antibiotics (e.g., quinolones and fluoroquinolones) are losing their effectiveness while others simply don’t work against Gram-negative bacteria. This class of bacteria includes strains responsible for food poisoning, urinary tract infections, pneumonia, cystic fibrosis and sepsis.
THE INVENTIONA UW–Madison researcher and collaborators have identified an antibiotic compound effective against many drug-resistant, Gram-negative and Gram-positive bacteria. The compound (5-nonyloxytryptamine) and its analogs are small molecule inhibitors that interfere with the bacterial membrane and prevent replication.

The compound has been reported as an anticancer drug but was not previously shown to have antimicrobial properties. It was identified by searching for compounds that cause E. coli bacteria to lack a copy of the chromosome following cell division.
APPLICATIONS
  • Antibiotic to treat infections and inhibit bacterial growth
  • Bacteria targets include Escherichia coli, Salmonella, Shigella, Bacillus, Listeria, Staphylococcus and Streptococcus species.
  • Topical and potentially systemic usage
KEY BENEFITS
  • Broad-spectrum weapon against Gram-negative, Gram-positive and antibiotic-resistant bacteria
STAGE OF DEVELOPMENTThe compound has been tested against a broad panel of human pathogens with promising results.

The University of Wisconsin and WARF –
A Single Location to Accelerate Translational Development of New Drugs

UW–Madison has the integrative capabilities to complete many key components of the drug development cycle, from discovery through clinical trials. As one of the top research universities in the world, and one of the two best-funded universities for research in the country, UW–Madison offers state-of-the-art facilities unmatched by most public universities.

These include the Small Molecule Screening Facility at the UW Comprehensive Cancer Center; the Zeeh Pharmaceutical Experiment Station, which provides consulting and laboratory services for developing formulations and studying solubility, stability and more; the Waisman Clinical Biomanufacturing Facility; the Wisconsin Institute for Medical Research, which provides UW–Madison with a complete translational research facility; and the innovative, interdisciplinary Wisconsin Institutes for Discovery, home to the private, nonprofit Morgridge Institute for Research and its public twin, WID, part of the university's graduate school. The highly qualified experts at these facilities are ready to work with you to create a library of candidates for drug development.
