Research Interests

Current research in the laboratory focuses on drug discovery against bacterial infections. Antibiotic resistance coupled with the paucity of new antibiotics in the pipeline represents a global health threat. If no action is taken to counter this threat more people will die of infectious diseases than of heart disease or cancer.

We have discovered small-molecule antivirulence agents against MRSA and other Gram-positive pathogens. These potential drugs do not kill the pathogen as antibiotics do, but disarm the pathogen of its deadly weapons, the toxins. It is the toxins that cause disease. In the absence of toxins, the pathogen is rendered harmless.

Methicillin-Resistant Staphylococcus Aureus (MRSA) is the most prevalent bacterial pathogen in the developed world causing an annual mortality rate of 20,000 in the US alone. MRSA is resistant to most antibiotics and it is widespread in hospitals as well as in the community where it infects even healthy people such as athletes. Untreated MRSA infections can lead to sepsis, a condition with a high rate of mortality.

The discoveries have been patented. Case Western Reserve University has licensed the intellectual property to biopharmaceutical company, Q2Pharma, Ltd. to conduct preclinical studies towards FDA approval for clinical studies to introduce this new game-changing therapy into the clinic.
