Heparan sulphate mimetics: Versatile tools for chemical biology. This project aims to develop chemical tools to study heparan sulphate-binding proteins. Heparan sulphate is a complex polysaccharide that is ubiquitously expressed on mammalian cells and interacts with proteins to mediate numerous biological and pathological functions. These interactions are poorly understood.

This project aims to develop chemical tools to study heparan sulphate-binding proteins. Heparan sulphate is a complex polysaccharide that is ubiquitously expressed on mammalian cells and interacts with proteins to mediate numerous biological and pathological functions. These interactions are poorly understood. This project will use homogeneous, structurally defined compounds to study heparan sulphate and its binding partners in biology. This is expected to lead to a better, molecular-level understanding of these fundamental processes, and may have future applications in biotechnology and drug development.Read moreRead less
Opening Up Access to L-Sugars through a Synergy of Experiment and Theory. This project aims to address a major bottleneck in the science of carbohydrates by developing the first broad-scope synthetic routes to L-sugars. L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make. This project expects to develop expeditious routes to L-sugars via a ....Opening Up Access to L-Sugars through a Synergy of Experiment and Theory. This project aims to address a major bottleneck in the science of carbohydrates by developing the first broad-scope synthetic routes to L-sugars. L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make. This project expects to develop expeditious routes to L-sugars via an innovative combination of synthetic and theoretical chemistry. Expected outcomes include a markedly increased capacity to access pure samples of L-sugar-based biomolecules, as needed for studying their biological functions. Significant benefits in the development of vaccines, diagnostics and biomaterials are anticipated.Read moreRead less
Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this pr ....Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this project will tackle. This proposal aims to create a technology to stabilise and deliver active gene material to target cells. The gene delivery tool developed in this project will advance biological research greatly with many potential future applications.Read moreRead less
Development of a multicomponent delivery system for oligonucleotides. Gene therapy has the ability to prevent faulty genes from causing disease, however the ability to deliver genetic material into specific cells remains a major barrier. Our research will overcome this hurdle by generating systems that are superior to existing technologies.
The mechanism of membrane disruption by antimicrobial peptides. Bacterial resistance to antibiotics is a growing crisis in modern medicine. Antibacterial peptides from Australian frogs represent a new class of potent and selective antibacterial agents. Understanding how these peptides kill bacteria but not vertebrate cells could lead to the design of new drugs for pharmaceutical and/or clinical purposes.
New antibiotics: engaging microbial chemical diversity. This project will explore Australian microbial biodiversity, to detect, isolate and identify new natural chemicals with potent and selective antibacterial properties. Knowledge of these molecules will inspire and inform the development of new classes of antibiotic, effective against multi-drug resistant infections.
Novel conotoxins that target ion channels and receptors. This project will discover peptides from cone snail venom that are potential drug candidates. The project will expand our knowledge of these biological active peptides and their mode of action. It will also protect key molecules through patent applications, providing a competitive edge for Australian biotechnology.
Toxins from Down Under: Novel tools to understand and modulate ion channels. Venoms are complex secretions containing biologically active components that have evolved over millions of years to specifically target the nervous systems of predators and prey. Two novel classes of toxins from snake and plant venoms that act on voltage-gated sodium channels, key proteins that regulate neuronal excitability, were recently identified by the research team. The project aims to develop and apply state-of-t ....Toxins from Down Under: Novel tools to understand and modulate ion channels. Venoms are complex secretions containing biologically active components that have evolved over millions of years to specifically target the nervous systems of predators and prey. Two novel classes of toxins from snake and plant venoms that act on voltage-gated sodium channels, key proteins that regulate neuronal excitability, were recently identified by the research team. The project aims to develop and apply state-of-the-art chemical, structural and biological techniques to unravel the molecular mechanisms through which these novel toxin classes act at their targets. Insights gained from this project will help identify and develop novel channel-modulating molecules that may have applications as neuroscience tools, diagnostics or drugs.Read moreRead less
Natural product scaffolds: an approach to privileged structures. Based on the fact that nature has provided approximately 50 per cent of current drugs, the purpose of this project is to identify scaffolds that are critical for the biological interactions. The expected outcome is to build libraries based on the scaffolds and identify new privileged structures for application in drug discovery.
Conotoxin diversification and evolution of venom peptides in cone snails. The marine snails of the genus Conus have evolved one of the most complex venoms that has emerged as a rich source of novel bioactive peptides. However, < 0.1% of their true potential has been characterised to-date. Using advanced genomic, proteomic, structural and pharmacological approaches pioneered in our laboratory, this study will decipher how conotoxin diversification from ancestral worm hunters facilitated the shift ....Conotoxin diversification and evolution of venom peptides in cone snails. The marine snails of the genus Conus have evolved one of the most complex venoms that has emerged as a rich source of novel bioactive peptides. However, < 0.1% of their true potential has been characterised to-date. Using advanced genomic, proteomic, structural and pharmacological approaches pioneered in our laboratory, this study will decipher how conotoxin diversification from ancestral worm hunters facilitated the shift in diet to modern fish and mollusc hunting species by determining the evolutionary trajectories of positively selected conotoxins. Investigation of the structure and function of these highly optimised venom peptides will provide new research tools and potential leads to new pharmaceuticals and agrochemicals.Read moreRead less
