An Investigation of Novel Sialylmimetics as Inhibitors of Rotavirus. Rotavirus causes severe gastroenteritis in infants worldwide. Over 125 million cases of diarrhoea and 800,000 deaths annually are attributed to rotavirus. The process that enables this debilitating and sometimes fatal disease to infect cells is poorly understood. This project aims to produce a range of unique chemical entities that will provide information about the way rotavirus infects cells.

The process that enables this debilitating and sometimes fatal disease to infect cells is poorly understood. This project aims to produce a range of unique chemical entities that will provide information about the way rotavirus infects cells. The chemical compounds produced in this study will be evaluated for their ability to prevent rotavirus from infecting cells. It is expected that this project will provide compounds that may ultimately be used as drugs for the treatment of rotavirus.Read moreRead less

New polymerisation processes for the synthesis of novel biopolymers. Synthetic peptide-based vaccines, formed via polymerisation of small bioactive motifs, possess several advantages over traditional approaches and promise to be the multi-disease targeting vaccines of the future. Disease targets will include influenza and hepatitis C viruses and a toxin from enteropathogenic Escherichia coli. These three diseases are in desperate need of novel vaccine approaches and the chemistries described in ....New polymerisation processes for the synthesis of novel biopolymers. Synthetic peptide-based vaccines, formed via polymerisation of small bioactive motifs, possess several advantages over traditional approaches and promise to be the multi-disease targeting vaccines of the future. Disease targets will include influenza and hepatitis C viruses and a toxin from enteropathogenic Escherichia coli. These three diseases are in desperate need of novel vaccine approaches and the chemistries described in this proposal represent a conceptual leap over traditional, and so far ineffective approaches investigated thus far. Synthetic antifreeze proteins and bioelastomers will also be constructed using our catalysis driven polymerisation process and applied to unmet medical and industrial needs.Read moreRead less
New methods for the synthesis of stable cyclic peptides. This proposal will design, synthesise and evaluate novel carbocyclic analogues of cyclic peptides which have application in the treatment of pain, diabetes management, malaria, and cancer therapy and diagnosis. The carbocyclic analogues will have improved biostability and will also provide the opportunity for oral administration. Carbacyclic analogues of insulin could lead to improved treatment of Australia's 1.2 million diabetics includi ....New methods for the synthesis of stable cyclic peptides.

The carbocyclic analogues will have improved biostability and will also provide the opportunity for oral administration. Carbacyclic analogues of insulin could lead to improved treatment of Australia's 1.2 million diabetics including many Aboriginal Australians who are particularly susceptible to Type II diabetes and its debilitating complications.Read moreRead less
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

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
Elucidating the Mode of Action of Nicotinic Receptor Ligands. Changes in brain function can cause human diseases such as epilepsy, schizophrenia and Alzheimer's disease. To develop new medicines to treat these conditions we need to study how drugs act in the brain. This project will use new methods of chemistry to make drugs, which will then be tested for biological activity at important brain receptors. This will tell us which compounds are most effective as potential drugs and also exactly whe ....Elucidating the Mode of Action of Nicotinic Receptor Ligands.

Development of a Diversity-Oriented Synthesis Platform. Genomic, proteomic and other studies of the molecular basis of disease are providing a constant stream of biomolecular targets for drug discovery. Identifying suitable drugs candidates to affect these targets centres around procuring a suitable library of compounds for screening. This application addresses some of the key issues related to the development of appropriate compound libraries for such screening programs.
