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
Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy ....Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy (the pyridine-2-carboxaldehyde isonicotinoyl hydrazone [PCIH] analogues) which show oral activity. These chelators undergo some interesting iron catalysed oxidation chemistry and it is vital that the mechanism of this reaction be elucidated to determine whether it will be of biological significance upon administration of these compounds as iron chelators.Read moreRead less
New Synthetic Routes to the Immobilisation of Mixed Valence Transition Metal Complexes on Conducting Metal Oxides. Highly coloured, electrochemically active transition metal dyes may find application electrochromic devices, where they may switch between contrasting coloured forms through a simple redox reaction. A prerequisite is that the dye be immobilised onto a solid conducting support whilst preserving the electrochemical and optical properties of the dye found in solution. This project tack ....New Synthetic Routes to the Immobilisation of Mixed Valence Transition Metal Complexes on Conducting Metal Oxides.

A prerequisite is that the dye be immobilised onto a solid conducting support whilst preserving the electrochemical and optical properties of the dye found in solution. This project tackles this problem through a combination of organic and inorganic synthesis to develop new electrochromic dyes that may be attached to mesoporous titania.Read moreRead less

Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom.

X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in mixtures. The current proposal is aimed at introducing new technology into the Australian National Beamline Facility that will greatly improve the quality and quantity of experiments that can be performed and extend studies into dilute solutions and protein samples.Read moreRead less
