Drug discovery is a complex and unpredictable endeavor with a high failure rate. Current trends in the pharmaceutical industry have exasperated these challenges and are contributing to the dramatic decline in productivity observed over the last decade. The industrialization of science by forcing the drug discovery process to adhere to assembly-line protocols is imposing unnecessary restrictions, such as short project time-lines. Our diseased-centered systems biology approach to drug discovery provides a unique infrastructure to identify novel druggable targets and therapeutic agents to increase the efficiency and success rate of drug discovery. One important component of our approach is the use and development of NMR-based metabolomics techniques to monitor the in vivo activity and selectivity of potential drugs. Similarly, NMR metabolomics can be used to monitor disease development, identify in vivo mechanisms of action for novel drugs, and evaluate mechanisms of drug resistance. Additionally, NMR metabolomics may be an invaluable approach to easily and rapidly diagnose human disease and assist in personalized medicine by monitoring a patient?s response to a particular treatment. Our NMR metabolomics technology, including our development of metabolomic tree diagrams and protocols for metabolite identification will be discussed. Also, our analysis of the mechanism of action and resistance of D-cycloserine (a TB drug), a metabolic signaling pathway for biofilm formation in S. aureus and S. epidermis , drug resistance in pancreatic cancer, and a potential diagnostic tool for multiple sclerosis will be presented.
