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
Development of metal probes for the selective recognition of DNA. Transition metal complexes with large aromatic ligands have recently been shown to bind DNA by intercalation. However, controversy continues over their base sequence and groove selectivity. We will synthesise a range of chiral metal complexes and screen these against combinatorial oligonucleotide libraries to determine their base sequence selectivity. The information obtained will help us design better intercalators that can be us ....Development of metal probes for the selective recognition of DNA. Transition metal complexes with large aromatic ligands have recently been shown to bind DNA by intercalation. However, controversy continues over their base sequence and groove selectivity. We will synthesise a range of chiral metal complexes and screen these against combinatorial oligonucleotide libraries to determine their base sequence selectivity. The information obtained will help us design better intercalators that can be used as sensitive molecular probes and may find application as antitumour drugs. Binding interaction between the complex and DNA will be studied by NMR spectroscopy.Read moreRead less
Experimental Charge Density Studies of Hydrogen Bonding. Hydrogen bonds, vital to all biological systems, exhibit extreme variation in chemical properties. Experimental analysis of hydrogen bonds, independent from previous theories and hypotheses, by using an expansion of current high resolution, ultra-low temperature X-ray crystallography is now possible. This allows experimental observation of electronic and electrostatic properties of previously unstudied hydrogen bonds, including weak hydrog ....Experimental Charge Density Studies of Hydrogen Bonding. Hydrogen bonds, vital to all biological systems, exhibit extreme variation in chemical properties. Experimental analysis of hydrogen bonds, independent from previous theories and hypotheses, by using an expansion of current high resolution, ultra-low temperature X-ray crystallography is now possible. This allows experimental observation of electronic and electrostatic properties of previously unstudied hydrogen bonds, including weak hydrogen bonds and those involving metal atoms. Comparison of experimental observations with predictions from high-level theoretical calculations and finally incorporation of these parameters into a prototype force field for computational chemistry will allow better predictions to be made in a range of areas including medicinal and materials chemistry.Read moreRead less
Antifreeze Proteins and Glycoproteins. Antifreeze proteins and glycoproteins permit many species of fish to survive in sub-zero oceans without freezing. These antifreeze compounds have potential applications in the frozen food industry (eg. maintaining the texture of ice cream), medical science (eg., cryosurgery) and veterinary science (eg. storage of sperm). Commercial applications are limited by the amounts of compounds available from fish and the lack of understanding of how these proteins ....Antifreeze Proteins and Glycoproteins. Antifreeze proteins and glycoproteins permit many species of fish to survive in sub-zero oceans without freezing. These antifreeze compounds have potential applications in the frozen food industry (eg. maintaining the texture of ice cream), medical science (eg., cryosurgery) and veterinary science (eg. storage of sperm). Commercial applications are limited by the amounts of compounds available from fish and the lack of understanding of how these proteins work. This research will study how natural and synthetic antifreezes inhibit ice growth in order to allow the rational design of new antifreezes and will identify new compounds with potential commercial applications as cryoprotectants.Read moreRead less

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

Disrupting Chemical Communication in Bacteria: A Novel and Effective Antimicrobial Strategy. Due to increased application of antibiotics for disease control, many pathogenic bacteria have developed resistance to existing antimicrobials. The infections associated with the resistant bacteria incur a high cost in terms of human health, well being and health care costs. Thus, there is a clear need to develop new antimicrobials that have a novel mechanism of action. The technology proposed here has ....Disrupting Chemical Communication in Bacteria: A Novel and Effective Antimicrobial Strategy.

Thus, there is a clear need to develop new antimicrobials that have a novel mechanism of action. The technology proposed here has the potential to deliver enormous health and social welfare benefits to the Australian population as well as commercial benefits to Australian industry, through provision of new, locally produced technologies for the control of bacterial virulence.Read moreRead less
