Microprobe and Nanoprobe Studies on Intracellular Disease Processes and Their Treatment. Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein.

Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein. Each of the different wavelengths of light provides complementary biochemical information that enables a deeper understanding of changes in cells that occur as a function of drug treatments and disease processes. This will provide unprecedented information as to where drugs go and how they are transformed inside cells that, in turn, may revolutionalise the way in which new drugs are designed that have higher specificity and fewer side effects.Read moreRead less
Metal complex-aminoglycoside conjugates for sequence-specific cleavage of ribonucleic acid (RNA). Ribonucleic acid (RNA) is emerging as an increasingly attractive drug target in the search for new approaches to combat diseases such as HIV/AIDS. This project will help position Australia at the forefront of research developments in the field of RNA-drug interactions, through the development of novel compounds that can cleave RNA molecules found in bacteria and retroviruses. In addition to a valuab ....Metal complex-aminoglycoside conjugates for sequence-specific cleavage of ribonucleic acid (RNA).

This project will help position Australia at the forefront of research developments in the field of RNA-drug interactions, through the development of novel compounds that can cleave RNA molecules found in bacteria and retroviruses. In addition to a valuable body of knowledge that will assist in the future development of new drugs, this project will provide high quality multi-disciplinary training for young scientists keenly sought by emerging medical and biotechnological industries, research organisations and universities.Read moreRead less
The roles of metal ions in glucose metabolism and the treatment of diabetes. Metal supplements, such as chromium and vanadium are consumed widely for their purported fat reduction and anti-diabetic activities. However, much is still to be learnt about the efficacy and safety of such metal ions when they are taken in supplements and whether they have an essential role in the prevention of diabetes or, in some instances, are a risk factor for cancer. The research will provide an understanding of ....The roles of metal ions in glucose metabolism and the treatment of diabetes. Metal supplements, such as chromium and vanadium are consumed widely for their purported fat reduction and anti-diabetic activities. However, much is still to be learnt about the efficacy and safety of such metal ions when they are taken in supplements and whether they have an essential role in the prevention of diabetes or, in some instances, are a risk factor for cancer. The research will provide an understanding of how these metal complexes exert their anti-diabetic effects and how they can be made safer and/or more efficacious for the treatment of type 2 diabetes, which is a rapidly expanding epidemic in developed countries.

Nanosized peptide nucleic acid - metal complex hybrids as catalysts for the cleavage of phosphate ester bonds in biological molecules. The information from Human Genome Project is being used to generate molecules with a variety of therapeutic and diagnostic applications. The capability to design, synthesise and manipulate functional molecules that mimic biological processes will underpin many emerging applications.

The information from Human Genome Project is being used to generate molecules with a variety of therapeutic and diagnostic applications. The capability to design, synthesise and manipulate functional molecules that mimic biological processes will underpin many emerging applications. In this project, macrocyclic metal complexes that catalyse the cleavage of phosphate ester bonds in biological molecules will be developed. Active complexes will be incorporated into nanosized peptide nucleic acid (PNA) - metal complex hybrids and applied as artificial enzymes in the sequence specific cleavage of RNA and DNA. Novel applications of these ?artificial enzymes? in biotechnology are anticipated.Read moreRead less
Functionalised MMP Inhibitors as Radiodiagnostic, Radiotherapeutic, and Radiation-Sensitising Agents for Metastatic Cancer. Identifying and treating malignant cancers is one of the major challenges facing the scientific and medical communities. In order to minimise side effects that accompany most treatments of cancer it is necessary to find ways of targeting the therapy to tumours and away from healthy organs. A difference between tumours and healthy tissues is the amount of the proteins (calle ....Functionalised MMP Inhibitors as Radiodiagnostic, Radiotherapeutic, and Radiation-Sensitising Agents for Metastatic Cancer. Identifying and treating malignant cancers is one of the major challenges facing the scientific and medical communities. In order to minimise side effects that accompany most treatments of cancer it is necessary to find ways of targeting the therapy to tumours and away from healthy organs. A difference between tumours and healthy tissues is the amount of the proteins (called MMPs) that tumours use to break out of their surroundings, to break into and out of the blood system, and to establish new colonies of cancer cells or metastases. This difference also distinguishes the most aggressive cancers. The purpose of this project is to develop means of identifying and targeting cancers using molecules that bind to these MMP proteins.Read moreRead less
