| We are interested in free radical damage in biological systems, particularly proteins, by species collectively described as reactive oxygen species (ROS). Proteases and ROS form a crucial partnership in many biological functions, both detrimental and beneficial. When proteins are damaged by ROS they are susceptible to increased rates of digestion by intracellular proteases. We are exploring one way of limiting the negative role of ROS and proteases by using redox active drugs to control protein oxidation. We are also interested in the mechanisms of protein repair by small molecules such as nitric oxide and nitroxides. We have active research programs developing antioxidant drugs of particular impact in the brain where ROS activation of matrix metalloproteinases (MMP’s) disrupts the blood brain barrier as well as inactivating alpha 1 – protease inhibitor. These drugs show strong activity in neurological protection and are of interest in diseases such as Ataxia Telangiectasia and Parkinson’s disease. |
