Novel target of amiloride analogues - picornaviral RNA polymerase. Picornaviruses cause a range of diseases such as poliomyelitis, meningitis, myocarditis, hepatitis A, neonatal sepsis and common cold. No antiviral treatment is available for these infections. Nearly 50% of antiviral drugs used in medicine are viral polymerase inhibitors; however picornaviral RNA polymerase has been largely overlooked as a drug target. We have discovered a group of compounds that inhibit picornaviral RNA polymera ....Novel target of amiloride analogues - picornaviral RNA polymerase. Picornaviruses cause a range of diseases such as poliomyelitis, meningitis, myocarditis, hepatitis A, neonatal sepsis and common cold. No antiviral treatment is available for these infections. Nearly 50% of antiviral drugs used in medicine are viral polymerase inhibitors; however picornaviral RNA polymerase has been largely overlooked as a drug target. We have discovered a group of compounds that inhibit picornaviral RNA polymerase. This project aims to define the inhibition mechanism and to evaluate a potential use of these compounds for antiviral drug development.Read moreRead less
New analgesics based on µ-conotoxins: structure-based design of helical mimetics. Diseases in which voltage-gated sodium channels are implicated are contributors to morbidity and mortality in the Australian population, and this project promises to provide new leads for the future development of drugs to treat such diseases, in particular analgesics for the treatment of chronic pain. The generation of these leads will entail the development of new approaches to mimicking key regions of peptides a ....New analgesics based on µ-conotoxins: structure-based design of helical mimetics. Diseases in which voltage-gated sodium channels are implicated are contributors to morbidity and mortality in the Australian population, and this project promises to provide new leads for the future development of drugs to treat such diseases, in particular analgesics for the treatment of chronic pain. The generation of these leads will entail the development of new approaches to mimicking key regions of peptides and proteins in drug-like molecules. This is a highly interdisciplinary project, spanning structural biology, molecular design, medicinal chemistry, molecular biology and electrophysiology, and the training of PhD graduates with such broad experience represents another national benefit of the project.Read moreRead less

The proposed facility will create new opportunities for collaborative programs with local and overseas researcher and will facilitate rapid progress in research programs across the entire University in particular those related to two ARC Centres of Excellence in which the University is a core partner.Read moreRead less
Raman and synchrotron spectroscopy of nano-scale drug interactions and molecular processes in single living cells. The need for potent low-cost drugs is ever increasing, yet effective ways to screen for new drugs remain elusive. A spectroscopic approach to screening drugs in living cells would seem a logical alternative to chemically based and morphological methods that are the status quo. In this context we are developing methodology to analyse molecular target sites in single living cells for ....Raman and synchrotron spectroscopy of nano-scale drug interactions and molecular processes in single living cells. The need for potent low-cost drugs is ever increasing, yet effective ways to screen for new drugs remain elusive. A spectroscopic approach to screening drugs in living cells would seem a logical alternative to chemically based and morphological methods that are the status quo. In this context we are developing methodology to analyse molecular target sites in single living cells for two of the most devastating diseases to afflict human kind, namely malaria and cancer. New ways of rapidly screening drugs in living cells prior to clinical trials will save an enormous amount of time, money and ultimately lives.Read moreRead less
Membrane structure and lipid interactions of the pore-forming toxin Equinatoxin II by NMR. The structure of Equinatoxin II, a pore-forming protein, will be determined in model cell membranes using solid-state NMR spectroscopy. The relationship of molecular structure to bioactivity and the nature of the pore-forming mechanism of this toxin will be determined. The results will aid in understanding how toxins lyse cells and could lead to the design of improved antibiotic peptides. Currently the st ....Membrane structure and lipid interactions of the pore-forming toxin Equinatoxin II by NMR.

The relationship of molecular structure to bioactivity and the nature of the pore-forming mechanism of this toxin will be determined. The results will aid in understanding how toxins lyse cells and could lead to the design of improved antibiotic peptides. Currently the structure of membrane proteins are difficult to determine and the newly developed techniques used for the structural determination of this membrane-associated protein will be suitable for studying other membrane proteins and receptors of pharmaceutical importance.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

Biosynthesis of multiple-nonmetal codoped titania nanoparticles for visible light photocatalysis. Nano-photocatalysts' are particles of very small size that can degrade organic wastes and harmful microorganisms, when exposed to light. Titania is the most commonly used photocatalyst, but the limitation with existing titania is that it is mainly active in ultraviolet (UV) light. UV-light cannot be used for indoor applications because UV is mutagenic and causes cancer.

Titania is the most commonly used photocatalyst, but the limitation with existing titania is that it is mainly active in ultraviolet (UV) light. UV-light cannot be used for indoor applications because UV is mutagenic and causes cancer. This project will use an eco-friendly approach to develop novel titania nanoparticles, which will be active in visible light. Success will lead to new options in the management of our organic wastes and wastewaters (global problems), plant disease control, clean clinical surroundings, and add value to our day-to-day products like self-cleaning windows, and textiles.Read moreRead less
