Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent ....Metal-Based Anti-inflammatory Drugs with High Efficacy and Low Side-Effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have widespread human and veterinary applications for the treatment of arthritis and other inflammatory diseases, but their utility is limited by often severe gastrointestinal, renal and cardiac side-effects. The recently heralded COX-2 inhibitors have not lived up to their expectations in terms of efficacy and side-effects, therefore, there is a need to develop new potent, but safer, NSAIDs. This project is aimed at using the results from new lead compounds to design NSAIDs with much greater efficacy and much less side effects than those currently available.Read moreRead less

Structural studies of catalysis and electron transfer by copper proteins. We propose to determine the crystal structures of five copper-containing proteins. Three are amine oxidases, enzymes that protect a wide range of organisms against toxic cell products (amines). Novel chemical modifications and crystallographic techniques will be used to test hypotheses for the enzyme mechanism. The results will provide a basis for the future manipulation of the enzymes' activities. Our other targets, s ....Structural studies of catalysis and electron transfer by copper proteins. We propose to determine the crystal structures of five copper-containing proteins. Three are amine oxidases, enzymes that protect a wide range of organisms against toxic cell products (amines). Novel chemical modifications and crystallographic techniques will be used to test hypotheses for the enzyme mechanism. The results will provide a basis for the future manipulation of the enzymes' activities. Our other targets, sulfocyanin and auracyanin-A, perform essential electron-transfer functions in an archaeon and a photosynthetic bacterium, respectively. The determination of their molecular structures will answer exciting questions about electron transfer in primitive organisms, and about the evolution of copper proteins as biological electron-transfer agents.Read moreRead less

Dietary selenium supplementation has great potential as a preventative treatment for a range of human health conditions, including cancer, that widely affect the Australian population. However, the adverse effects of such treatments are not fully recognised. This project will increase our knowledge of how selenium compounds are stored and utilised in the body and relate the information to clinical observations regarding dietary intake of selenium and other compounds. The new understanding generated will delineate the conditions for safe intake, so that the beneficial effects associated with selenium supplementation may be harnessed more effectively.Read moreRead less
