Smart bio-mimetic self-assembled gels for biomedical applications. Advanced materials that can be used to deliver drugs, repair scars and damaged tissue are the holy grail of regenerative medicine. Recently, a class of materials called self-assembled gels have shown enormous potential in this regard. Self-assembled gels have already demonstrated their use in drug delivery and are showing great promise in the treatment of spinal injuries.

Advanced materials that can be used to deliver drugs, repair scars and damaged tissue are the holy grail of regenerative medicine. Recently, a class of materials called self-assembled gels have shown enormous potential in this regard. Self-assembled gels have already demonstrated their use in drug delivery and are showing great promise in the treatment of spinal injuries. This project will create an even smarter version of these gels with biological activity, especially targeting cancer and suppressing tumour growth after surgery. Our approach will help to ensure that Australians can take a leading role in this highly exciting new area of biomedical research.Read moreRead less
Towards an influenza virus glycan interaction map (Glycointeractome). This project will use nuclear magnetic resonance (NMR) spectroscopy to map carbohydrate interaction used by the virus to cause infection and spread. This information will provide new direction in anti-influenza drug discovery.
Escaping Bio-Assay Guided Isolation: Nature's Tools for Chemical Biology. The project aims to transform the approach to identify novel biologically active compounds that occur in nature. For decades, natural product chemistry has centred on bio-assay guided isolation, but it has become increasingly difficult to isolate novel compounds. While de-replication strategies detect the presence of known compounds using databases, more impact would be achieved by directly detecting novel compounds. Nucle ....Escaping Bio-Assay Guided Isolation: Nature's Tools for Chemical Biology. The project aims to transform the approach to identify novel biologically active compounds that occur in nature. For decades, natural product chemistry has centred on bio-assay guided isolation, but it has become increasingly difficult to isolate novel compounds. While de-replication strategies detect the presence of known compounds using databases, more impact would be achieved by directly detecting novel compounds. Nuclear magnetic resonance (NMR) spectroscopy detects every molecule that has a proton and is quantitative. This project plans to develop a NMR technique to escape bio-assay guided isolation by analysing a fraction library. Biotechnology innovation is dependent on novel compounds to provide new products. Replacing ‘grind and find’ with a technique that never lies would be transformational.Read moreRead less
Inhibition of membrane-bound carbonic anhydrases with small molecules as a novel approach to target a safe and effective treatment for solid tumours. Over 85 per cent of human cancers are solid tumours and the prognosis for patients with advanced solid tumours is extremely poor owing to resistance to conventional chemo- and radio- therapies. Our research will underpin the development of new, safe and effective drug treatment options for cancer patients with solid tumours.
Lymphotropic prodrugs: a novel mechanism for targeted drug delivery. This project aims to design chemically modified drugs that target drug delivery specifically to white blood cells. This approach promises to maximise drug action and simultaneously reduce toxicity for diseases where lymphocytes are the major drug target. These include autoimmune disease, leukaemia, lymphoma, HIV, transplant rejection and diabetes.
Synthesis and Applications of Antifreeze Proteins and Glycoproteins. Many cells are damaged when they are chilled below body temperatures thus limiting shelf-life for applications. For example, storage of human blood platelets is limited to 5 days at 22 degrees. This research will produce molecules that can be used in the fields of agriculture (in vitro fertilization techniques, development of improved blood lines), aquaculture and human reproductive technologies, where ice crystal growth and fr ....Synthesis and Applications of Antifreeze Proteins and Glycoproteins. Many cells are damaged when they are chilled below body temperatures thus limiting shelf-life for applications. For example, storage of human blood platelets is limited to 5 days at 22 degrees. This research will produce molecules that can be used in the fields of agriculture (in vitro fertilization techniques, development of improved blood lines), aquaculture and human reproductive technologies, where ice crystal growth and freezing are damaging. This outcome will be achieved by the synthesis of molecules that mimic natural products that allow fish to survive in the icy Arctic and Arctic Oceans and study how they are able to protect cells and tissues from damage in these extreme environments.Read moreRead less
Pushing The Boundaries Of Flow Chemistry – Towards New Anti-Viral Agents. Synthetic chemistry approaches to new drugs rely on access to robust reliable reactions. Traditionally these approaches are highly wasteful with the pharmaceutical industries producing five to a hundred kilograms of waste per kilogram of product. Total flow chemistry approaches will significantly reduce waste, allow rapid reaction sequence optimisation, and seamless scale up. In a collaborative effort spanning Australia, G ....Pushing The Boundaries Of Flow Chemistry – Towards New Anti-Viral Agents. Synthetic chemistry approaches to new drugs rely on access to robust reliable reactions. Traditionally these approaches are highly wasteful with the pharmaceutical industries producing five to a hundred kilograms of waste per kilogram of product. Total flow chemistry approaches will significantly reduce waste, allow rapid reaction sequence optimisation, and seamless scale up. In a collaborative effort spanning Australia, Germany and the USA, in an exemplar of a real world application, this project will produce benefits not only in enhanced and greener synthetic approaches, but also in the development of strategies for the identification of small molecules, the precursors to a new mode of action class of anti-viral drugs.Read moreRead less
Downsizing proteins to equipotent small molecules that activate cells. The project aims to downsize large, expensive, naturally occurring proteins to small, cheap, synthetic organic compounds engineered to have the same functions. If the methods are generally applicable for different proteins, they could be used to create new pharmaceuticals, diagnostics, flavours, perfumes, catalysts and industrial materials.
Making peptides orally bioavailable. Bioactive peptides are exceptionally useful molecules, however to fully realise their exciting applications key limitations need to be overcome: they can't be delivered orally and they do not last long in the body. This project aims to develop a molecular tag that can dramatically enhance both the oral absorption and time in the body of a peptide. This will include identifying the key elements of the tag required for function, the breadth of peptide cargoes i ....Making peptides orally bioavailable.

This project aims to develop a molecular tag that can dramatically enhance both the oral absorption and time in the body of a peptide. This will include identifying the key elements of the tag required for function, the breadth of peptide cargoes it can be applied to and the mechanisms underlying this technology. The outcomes of this project will facilitate the future development of peptides for biotechnology, pharmaceutical and veterinary applications.Read moreRead less
Exploring the novel structural features of influenza virus sialidase. The outcomes of this project will provide a deeper mechanistic understanding of influenza virus sialidase and the importance of the enzyme's flexible loops in carbohydrate recognition. Specifically, this project will improve our understanding of fundamental aspects of inhibitor binding by influenza virus sialidases.
