Examination of unique tear lipids and their role in the tear film's structure and function. The tear film lipid layer covers the eye, stabilises the tears and prevents their evaporation. Yet its structure, function and composition are yet to be fully elucidated. The aim of this project is to fully characterise the unique lipids in this layer, the long-chain omega-hydroxy fatty acids (not found elsewhere in the body), and to determine their role in its structure and function.

The aim of this project is to fully characterise the unique lipids in this layer, the long-chain omega-hydroxy fatty acids (not found elsewhere in the body), and to determine their role in its structure and function. The project is significant because the unique combination of skills including synthetic chemistry, mass spectrometry, lipidomics, biochemistry, biophysics which aim to result in a major shift in the understanding of this layer.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 Pyrrolopyrimidines as Inhibitors of ATP-Binding Proteins. This project seeks to generate analogues of natural products that have been found to be active against cancer cells and tropical parasites. The new materials produced by this project will aid in the study of biochemical processes involved in diseases such as cancer and lymphatic filariasis, thus leading the way to development of these compounds as potential treatments for such diseases.
High Pressure and Fluorous Approaches to Fostriecin Libraries: New Therapeutic Opportunities. The natural product, Fostriecin, displays considerable broad-spectrum anti-cancer activity, acting via a novel mechanism. However, this activity is tempered by its considerable instability, being too unstable to be used as a therapeutic agent. Using state-of-the-art approaches we will, rapidly generate libraries of more stable and biologically active fostriecin analogues and examine their potential to b ....High Pressure and Fluorous Approaches to Fostriecin Libraries: New Therapeutic Opportunities.

Using state-of-the-art approaches we will, rapidly generate libraries of more stable and biologically active fostriecin analogues and examine their potential to be used anti-cancer agents. This project represents an opportunity for Australia to take a significant, innovative lead in the development of hitherto unforseen therapeutic agents.Read moreRead less
Fluorous Chemistry: New tagging agents and heterocyclic-based fluorous surfactants. Fluorous chemistry is emerging as a powerful adjunct to areas of conventional parallel and combinatorial organic syntheses, and its introduction has revolutionised separation technologies. In this project two new fluorous tagging strategies will be investigated in an effort to broaden the scope of reagents that can used in synthesis. Efforts will be directed to chiral auxiliaries and to fluorous catalyst ligands. ....Fluorous Chemistry: New tagging agents and heterocyclic-based fluorous surfactants. Fluorous chemistry is emerging as a powerful adjunct to areas of conventional parallel and combinatorial organic syntheses, and its introduction has revolutionised separation technologies. In this project two new fluorous tagging strategies will be investigated in an effort to broaden the scope of reagents that can used in synthesis. Efforts will be directed to chiral auxiliaries and to fluorous catalyst ligands. In addition, a novel class of fluorous surfactant will be investigated, for its surface properties (including its ability to self assemble) and for its utility in two specific applications, selective membrane-bound protein extraction (relevant to proteomics) and ophthalmics (biomaterials).Read moreRead less

Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production. Our research depending on this technique includes many fundamental and applied topics from a wide range of disciplines, such as developing portable detection devices for explosives, finding more efficient and sustainable ways to explore for ore, investigating the effects of climate change on marine ecosystems and improving salinity and drought tolerance of crops.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.

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

Aberrant glycosylation and over-production of glycoproteins is associated with numerous cancer types (including breast, prostate, ovarian and small lung) and are recognised as promising agents for disease diagnosis and vaccine development. A range of cancer-associated glycoproteins will be synthesised in this research program using a number of novel chemical technologies. These glycoproteins will be used to develop cancer vaccines and diagnostics. Cancer is a severe burden on the Australian community and on the economy, therefore this research will be of significant benefit to Australia.Read moreRead less
