Chemical Biology of Nitrogen Oxides; New Detection Techniques and Donors of Nitrogen Oxides; Drug Development Nitric oxide (NO), which is synthesized in the body via enzymatic oxidation of L-arginine, is critical to numerous physiological functions but also can contribute to the severity of diseases such as cancer or pathophysiological conditions such as stroke. This diversity in the responses to NO biosynthesis is a reflection of the diverse chemistry of NO. For instance NO can alter the function of enzymes by binding to metal centers. This type of interaction could result in outcomes as disparate as control of blood pressure or death of an invading bacterium. NO can also be readily converted to higher nitrogen oxides such as N2O3, NO2 or ONOOH, which have discrete chemical and biological properties. The ultimate result will depend upon numerous factors, particularly the location and concentration of NO produced. Therefore, site-specific modulation of NO concentration offers intriguing therapeutic possibilities for an expanding list of diseases. The overall goal of my research is to provide pharmacological therapies for diseases such as cancer, heart failure and stroke. Accomplishing this goal requires both the development of compounds to deliver NO and other nitrogen oxides and a full understanding of the biological consequences of nitrogen oxide production by these compounds. To this end, we are currently engaged in the investigation of the reactivity of nitrogen oxides at the molecular, biomolecular, systemic and whole organism levels.
