The development of a rapid diagnostic test for heparanase activity. Heparanase is an enzyme that has been implicated in a number of disease states such as cancer, arthritis, multiple sclerosis and other inflammatory diseases. Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this a ....The development of a rapid diagnostic test for heparanase activity.

Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this assay could provide a useful diagnostic tool in a clinical environment that would allow for the rapid assessment of these diseases, their progression and indeed response to therapy.Read moreRead less

Society is facing the triple challenges of food security, environmental degradation and climate change The availability of new, highly-efficient fertilisers is critical for addressing these challenges, and for the competitive advantage of the Australian fertiliser industry.Read moreRead less
Strategies for the detection of designer steroids in greyhounds. 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 ....Strategies for the detection of designer steroids in greyhounds. 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 outcome of ....Synthesis and Analysis of Canine Anabolic Steroid Metabolites. The Australian racing industry is a major driver of economic activity.

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
Praziquantel: a unique pharmaceutical challenge. Generating effective and affordable drugs for the treatment of tropical diseases is a huge public health challenge. We will pioneer an open source approach to collaborative research in drug discovery. We aim to discover an inexpensive route to an important pharmaceutical so that it can be greatly improved and distributed to the affected populations for a realistic price. Success in this project will improve the lives of millions of sufferers of th ....Praziquantel: a unique pharmaceutical challenge.

We will pioneer an open source approach to collaborative research in drug discovery. We aim to discover an inexpensive route to an important pharmaceutical so that it can be greatly improved and distributed to the affected populations for a realistic price. Success in this project will improve the lives of millions of sufferers of this disease, and demonstrate a new way of doing research on drugs for related diseases such as malaria. Read moreRead less
Synthesis and evaluation of anti-microbial porphyrin adducts for the targeted inhibition of Porphyromonas gingivalis. At present the effectiveness of therapy for inflammatory disease of the gum tissue (periodontitis) is limited by the lack of a selective anti-microbial agent. The investigators have discovered a novel mechanism of binding of the blood product porphyrin by a unique receptor of a key pathogen implicated in this disease. By exploiting this knowledge a modified porphyrin linked to an ....Synthesis and evaluation of anti-microbial porphyrin adducts for the targeted inhibition of Porphyromonas gingivalis. At present the effectiveness of therapy for inflammatory disease of the gum tissue (periodontitis) is limited by the lack of a selective anti-microbial agent. The investigators have discovered a novel mechanism of binding of the blood product porphyrin by a unique receptor of a key pathogen implicated in this disease. By exploiting this knowledge a modified porphyrin linked to an antibiotic was shown to have a selective effect on the target organism. Refinement of this complex has the potential to provide a clinically useful, selective agent.Read moreRead less
Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techn ....Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techniques allow us for the first time to fully investigate this approach which if successful will be applicable to many other helical peptides and therefore could be an important drug development technique.Read moreRead less
Development of Chemoenzymatic Methods for the Selective Elaboration of Polyfunctionalised Therapeutic Agents to Oligomers with Improved Efficacy. The aims of the project are to screen a novel collection of genetically engineered enzymes for their capacity to selectively manipulate proven therapeutic agents so that, ultimately, much more potent polymeric derivatives of the agent/drug can be obtained. The combined use of enzyme libraries and chemical manipulations to generate more powerful polymer ....Development of Chemoenzymatic Methods for the Selective Elaboration of Polyfunctionalised Therapeutic Agents to Oligomers with Improved Efficacy. The aims of the project are to screen a novel collection of genetically engineered enzymes for their capacity to selectively manipulate proven therapeutic agents so that, ultimately, much more potent polymeric derivatives of the agent/drug can be obtained. The combined use of enzyme libraries and chemical manipulations to generate more powerful polymeric variants of already established drugs has never been undertaken previously in Australia. This approach has the capacity to generate hitherto inaccessible classes of therapeutic entities and to provide a new and unique technology platform for the country's biotechnology industry.Read moreRead less
