Summary
Development of Innovative Chemical Tools for Studying Glycosyltransferases . This project aims to develop chemical probes capable of selectively binding and inhibiting two classes of carbohydrate processing enzymes known as O-linked beta-N-acetylglucosamine transferase and sialyltransferases. These enzymes are overexpressed in various cancers and play critical roles in cancer progression. Probes will be developed to analyse the activities of these enzymes in cancer cells.
Liposaccharide based peptide and vaccine delivery systems: improving the bioavailability and immunogenicity of Luteinizing Hormone-Releasing Hormone. This project aims to develop new lipid- and sugar-based drug delivery systems for Luteinizing-hormone-releasing hormone (LHRH), a hormone which regulates the level of enzymes involved in fertility conditions and prostate cancers. This technology could be extended to significantly increase the number of drugs available on the market, such as peptide ....Liposaccharide based peptide and vaccine delivery systems: improving the bioavailability and immunogenicity of Luteinizing Hormone-Releasing Hormone.

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 will use homogeneous, structurally defined compounds to study heparan sulphate and its binding partners in bio ....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 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
Harnessing molecular strain for drug discovery and bioconjugation. Peptides and proteins are increasingly important therapies for the treatment of disease. Nevertheless, the synthesis and optimisation of these high-value compounds still relies primarily on technologies developed decades ago. There is a desperate need for modern strategies to unlock the full potential of peptides and proteins for diverse applications in drug discovery. This interdisciplinary research aims to develop new tools for ....Harnessing molecular strain for drug discovery and bioconjugation. Peptides and proteins are increasingly important therapies for the treatment of disease. Nevertheless, the synthesis and optimisation of these high-value compounds still relies primarily on technologies developed decades ago. There is a desperate need for modern strategies to unlock the full potential of peptides and proteins for diverse applications in drug discovery. This interdisciplinary research aims to develop new tools for the construction and modification of peptides and proteins by harnessing the energy in a unique class of strained molecules. A focus on peptide-based inhibitors of the proteasome, a critical target for modern cancer treatments, should provide future health and economic benefits for the Australian community.Read moreRead less

This project aims to develop a new synthetic approach to valuable amino acid derivatives and their rapid incorporation into peptide analogues, including promising new antibiotic candidates. This project expects to generate knowledge in the chemical and biological sciences and build scientific capacity to address the global rise of antimicrobial resistance. It is anticipated that this will provide direct health and economic benefits by establishing a powerful platform for peptide drug design.Read moreRead less
Sulfoxide Polymers - A New Paradigm in Polymer Design. Low fouling polymers are important for moderating interactions of molecules and particles with cells. In pharmaceutical sciences they are essential tools for extending the pharmacokinetics of dissolved drugs. However, the widely-used low-fouling polymer, poly(ethylene glycol) (PEG) has been recently reported to induce formation of anti-PEG antibodies. Polymeric alternatives to PEG are thus desperately needed. We introduce in this project sup ....Sulfoxide Polymers - A New Paradigm in Polymer Design. Low fouling polymers are important for moderating interactions of molecules and particles with cells. In pharmaceutical sciences they are essential tools for extending the pharmacokinetics of dissolved drugs. However, the widely-used low-fouling polymer, poly(ethylene glycol) (PEG) has been recently reported to induce formation of anti-PEG antibodies. Polymeric alternatives to PEG are thus desperately needed. We introduce in this project super-hydrophilic polymers incorporating sulfoxide groups, mimics of the polar solvent DMSO. The project aims to explore how polymer architecture can enhance biocompatibility and reduce biofouling. The outcome will be a new class of low-fouling polymeric materials with broad application in the biosciences.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.

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
Synthesis and Biological Evaluation of Australian Sponge Metabolites. The development of concise and flexible syntheses of Australian marine natural products and analogues of ecological/therapeutic significance will emerge. Such activities will lead to the identification and evaluation of molecular entities of value in managing marine environments and help to enhance chemical synthesis capacity in Australia.
