Strategies for the detection of designer steroids in greyhounds. This project aims to develop strategies to detect designer steroids in racing greyhounds to safeguard industry integrity and animal welfare. These strategies include in vivo and comparative in vitro studies of steroid metabolism, mass-spectrometric elucidation of metabolite structures, and synthesis of putative steroid metabolites with different stereochemistries and oxidation patterns as reference materials. This project will use major metabolites identified by these studies to develop analytical procedures to test for drug abuse at greyhound race meetings. The project will target twelve readily available designer steroid supplements that have significant risk of abuse.Read moreRead less
Synthesis and Analysis of Canine Anabolic Steroid Metabolites. The Australian racing industry is a major driver of economic activity. In NSW, racing is estimated to contribute $1,000 million to GDP, $151 million to Government revenue and provide 50,000 jobs. The future security and prosperity of the racing industry depends on maintaining the highest standards of integrity in the public eye, and this in turn depends on the enforcement of regulations relating to illicit substances.

The future security and prosperity of the racing industry depends on maintaining the highest standards of integrity in the public eye, and this in turn depends on the enforcement of regulations relating to illicit substances. The outcome of this project will be the introduction of robust methods of analysis for potential drug abuse in greyhound racing that will position Australia as a world leader in the field.Read moreRead less
Connecting soil nitrogen and plant uptake for greener agriculture. This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system.

This project will use synthetic organic chemistry, biochemistry, root and rhizosphere biology and rhizosphere modelling to establish detailed mechanistic knowledge of the nitrogen (N) transport and uptake processes at the soil-root interface to develop new, efficient urease and nitrification inhibitors for reliable provision of N to the plant/root system. The reduction of excessive N fertilisation has significant environmental benefits by reducing greenhouse gas emissions and water pollution. This project will lead to a breakthrough for the triple challenge of food security, environmental degradation and climate change, while improving plant productivity and increasing the profitability of agriculture through lower fertiliser costs.Read moreRead less
pH Switching of Radical Reactivity and Orbital Conversion. Radicals are reactive species that have an unpaired electron, which is usually located in the highest occupied orbital. This proposal uses a combination of theory and experiment to design a new class of radical anions whose unpaired electron is not the highest occupied orbital, and whose electronic configuration reverts to the normal aufbau configuration upon protonation. These special radical anions will display unprecedented radical st ....pH Switching of Radical Reactivity and Orbital Conversion. Radicals are reactive species that have an unpaired electron, which is usually located in the highest occupied orbital. This proposal uses a combination of theory and experiment to design a new class of radical anions whose unpaired electron is not the highest occupied orbital, and whose electronic configuration reverts to the normal aufbau configuration upon protonation. These special radical anions will display unprecedented radical stability that is pH switchable, as well as ferromagnetism and conductivity upon oxidation. This project will exploit these unusual properties in the design of pH-switchable protecting groups for radicals for synthesis and polymerisation, and determine their role in oxidative stress and enzyme kinetics.Read moreRead less

Experimental and Computational Investigations into Enantioselective Domino Sequences. This research program aims to develop more efficient methods for the chemical synthesis of organic substances: the materials that make up all known life forms, our medicines, and many designed materials.

This research program aims to develop more efficient methods for the chemical synthesis of organic substances: the materials that make up all known life forms, our medicines, and many designed materials. This research involves primarily the invention of new, enabling science. Specifically, we are trying to develop new and very general strategies to make organic compounds selectively and more efficiently than before. A more efficient chemical synthesis means less waste, lower energy consumption and less environmental impact. Research of this kind is absolutely essential for the development of new medicines and materials. Australia lags behind many of the world's developed countries in this very important area of endeavour.Read moreRead less

Organic molecules are an integral part of our world - in us, around us and, importantly, in our medicines. Chemists design experiments to make specific molecules by mixing the appropriate chemicals. Often, however, the outcome can't be predicted. We are developing ways to accurately predict these outcomes using computer modelling of chemical reactions. This will allow us to better understand reactions and make molecules more efficiently. Such research is the basis for the development of new pharmaceuticals. Few people in Australia are working in this area and we expect to train four to six people during the course of this project.Read moreRead less

Designing Organocatalysts to Achieve Hyperpolarised Magnetic Resonance. Magnetic resonance techniques (such as MRI scans) suffer from an inherent insensitivity problem. In medical imaging, this can hamper diagnosis and mean long scan times for patients.

Magnetic resonance techniques (such as MRI scans) suffer from an inherent insensitivity problem. In medical imaging, this can hamper diagnosis and mean long scan times for patients. This project aims to chemically develop catalysts which dramatically increase sensitivity, producing a signal that is thousands of times more visible. This project is significant as these catalysts can turn common, harmless molecules in the body - even water - into visible tracers. The expected outcomes of this project include the synthesis and understanding of these catalysts which will be chemically fine-tuned to maximise their effectiveness. Potential benefits include translation to MRI applications to improve diagnosis and treatment, or chemical monitoring.Read moreRead less
