Mycobacterial Cholesterol Degradation: A Unique Metabolic Weakness? This project aims to understand the use of the steroid cholesterol as a source of essential metabolic building blocks by bacteria. Cholesterol utilisation is a key feature of many bacterial pathogens which have evolved to survive in niche environments.

This project aims to understand the use of the steroid cholesterol as a source of essential metabolic building blocks by bacteria. Cholesterol utilisation is a key feature of many bacterial pathogens which have evolved to survive in niche environments. By understanding the initial step in cholesterol degradation and the bioinorganic and bioorganic chemistry of the metalloenzymes that catalyse it, this work aims to develop strategies to block this activity. This will turn a key strength of these bacteria into a potent weakness and will generate the proof of principle and knowledge required for the future development of effective strategies to combat pathogenic bacteria.Read moreRead less

Metals in Medicine. Metal-based drugs account for several billion dollars of pharmaceutical sales worldwide, but proportionally much less research and development has focussed on this area than organic drugs. Australia has played a pivotal role in the early development of metal-based pharmaceuticals, which remains a research strength. The dual aims of the initiative are to provide a network for a vibrant industry based around metals in medicine and to improve the health of Australians. The ini ....Metals in Medicine. Metal-based drugs account for several billion dollars of pharmaceutical sales worldwide, but proportionally much less research and development has focussed on this area than organic drugs. Australia has played a pivotal role in the early development of metal-based pharmaceuticals, which remains a research strength. The dual aims of the initiative are to provide a network for a vibrant industry based around metals in medicine and to improve the health of Australians. The initiative will foster national and international cross-disciplinary collaborations to address the impediments holding back Australia's potential to take full advantage of our research strength in metals in medicine.Read moreRead less
Challenging targets in rare earth metal-organic chemistry. This project aims to prepare highly reactive rare earth organometallic and metal-organic compounds, especially from the free metals, and to determine their structures and reactivity. Abundant rare earth resources position Australia to be a major supplier of these strategic elements. The challenging target systems include coordination stabilised novel ligands, pseudo-Grignard reagents LnR(X) including the rare fluorides, complexes primed ....Challenging targets in rare earth metal-organic chemistry. This project aims to prepare highly reactive rare earth organometallic and metal-organic compounds, especially from the free metals, and to determine their structures and reactivity. Abundant rare earth resources position Australia to be a major supplier of these strategic elements. The challenging target systems include coordination stabilised novel ligands, pseudo-Grignard reagents LnR(X) including the rare fluorides, complexes primed for carbon-fluorine activation, and intermediates from use of lanthanoid reagents in organic synthesis. The project will provide a knowledge base and expertise for the utilisation of Australia's abundant rare earths and will transform the current behaviour of the elements. It builds the expertise and knowledge needed to underpin Australian rare earth processing and develops the breakthrough science needed for new applications in fine chemical manufacturing, catalysis and recycling.Read moreRead less
Dinuclear Ruthenium Complexes as Sequence- and Structure-Selective Binding Agents for DNA. Studies of the interaction of mononuclear metal complexes with DNA have greatly increased our understanding of the ways that small molecules recognise particular sites on DNA. However, in order to design drugs that target specific genes, and hence be potentially capable of controlling gene expression, it is necessary to study the binding of metal complexes that can associate with larger segments of DNA. ....Dinuclear Ruthenium Complexes as Sequence- and Structure-Selective Binding Agents for DNA. Studies of the interaction of mononuclear metal complexes with DNA have greatly increased our understanding of the ways that small molecules recognise particular sites on DNA. However, in order to design drugs that target specific genes, and hence be potentially capable of controlling gene expression, it is necessary to study the binding of metal complexes that can associate with larger segments of DNA. Using the combined expertise of the applicants, it is proposed to stereospecifically synthesise dinuclear complexes and study their DNA binding. This will greatly assist in the development of drugs that can selectively target genes and altered DNA.Read moreRead less
Chemical and Biochemical Characterisation of Novel Iron Chelators with Therapeutic Potential. Resistance by cancers to established chemotherapeutics is a growing problem in the community and one that demands the development of new strategies.

Resistance by cancers to established chemotherapeutics is a growing problem in the community and one that demands the development of new strategies. Chelators that target the essential element iron within cancer cells represent a novel and promising approach to this problem. The Chief Investigators represent a unique combination of expertise in coordination chemistry and the biochemistry of iron chelation. They have discovered and characterised new chelators that show marked anticancer activity, and act by a new mechanism that overcomes problems of resistance. In this project they will pursue a course that will lead to a greater understanding of how these compounds work with the outcome that new effective anticancer drugs may emerge.Read moreRead less

Summary
A novel fully inorganic quantum dots based solar cell. A fully-inorganic quantum dots solar cell will be constructed by using cheap chemical solution techniques. The development of the new 3rd generation solar cell is aimed to realise the high-efficiency, low-cost, and well-stability of solar cells. It would dramatically increase commercial viability of quantum solar cells.
Advancing the chemistry of topical rare earth metals. Abundant rare earth resources positions Australia to be a major supplier of these strategic elements and overcome the shortage created by the Chinese monopoly and export restrictions. This project will build the expertise and knowledge needed to underpin Australian rare earth processing and develop the breakthrough science needed for new applications.
Electrochemically Driven Molybdoenzyme Catalysis. Enzymes that catalyse oxidation and reduction reactions need to exchange electrons with their substrate and this supply of electrons needs to be sustained. Artificially reconstituted systems can be developed where the enzyme is coupled with an electrode and the current (electrons) exchanged during the reaction are measured directly. In this project we will reveal whether some unusual and unexplained electrochemical phenomena seen before are relat ....Electrochemically Driven Molybdoenzyme Catalysis.

Artificially reconstituted systems can be developed where the enzyme is coupled with an electrode and the current (electrons) exchanged during the reaction are measured directly. In this project we will reveal whether some unusual and unexplained electrochemical phenomena seen before are related to the properties of the enzymes themselves or the ways in which their experiments have been conducted.Read moreRead less
