The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

A facility for the analysis of biological macromolecules and their interactions with ligand molecules is required to support a large number of research projects in high priority areas including mechanisms of aging, drug development and bio/nanotechnology at three different universities. The instrumentation will (i) afford quantitative measurements of binding affinities between biological and chemical macromolecules, which are available only in small quantities, and small, drug related molecules (by microcalorimetry and dual polarization interferometry), and (ii) provide equipment necessary for sample characterization and purification prior to quantitative measurements (CD spectroscopy, and FPLC equipment).Read moreRead less
Understanding the Chemical Processes Involved in the Metabolism of Peptide Hormones. Peptide hormones regulate normal physiological activity in humans, and their over-production causes diseases such as cancer. The aims of this project are: to delineate the chemical processes through which these hormones are produced; to develop inhibitors of enzymes involved in hormone production, and agonists and antagonists of receptors through which the hormones act; and to study the ability of the inhibitors ....Understanding the Chemical Processes Involved in the Metabolism of Peptide Hormones. Peptide hormones regulate normal physiological activity in humans, and their over-production causes diseases such as cancer. The aims of this project are: to delineate the chemical processes through which these hormones are produced; to develop inhibitors of enzymes involved in hormone production, and agonists and antagonists of receptors through which the hormones act; and to study the ability of the inhibitors, agonists and antagonists to override and bypass the chemical control mechanisms through which hormone levels are usually maintained at homeostasis. The research is expected to lead to a better fundamental understanding of hormone metabolism, and to underpin the basis for the development of new disease therapies.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
Targeting DNA with Dynamic Combinatorial Chemistry. The interaction of molecules with DNA, the molecule that controls genetic information, is fundamental to drug design, diagnosis of disease and the environment. Chemists usually synthesise these molecules in the laboratory. We will use an innovative new approach to producing molecules that interact with DNA, that as fast and efficient and mirrors the processes used by Nature to make natural products. This research may lead to the design of new ....Targeting DNA with Dynamic Combinatorial Chemistry.

Chemists usually synthesise these molecules in the laboratory. We will use an innovative new approach to producing molecules that interact with DNA, that as fast and efficient and mirrors the processes used by Nature to make natural products. This research may lead to the design of new therapeutics, diagnostics and applications that will benefit the Australian community, and will provide excellent training of researchers in skills required for employment in the biotechnology and pharmaceutical fields.Read moreRead less
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

Medicinal chemistry is constantly being challenged to develop efficient methodologies for the synthesis of compounds for drug discovery. Following completion of the Human Genome project, the cloning and expression of new proteins will proceed at an accelerated rate. In the absence of biochemical knowledge of the target protein there is a growing interest in techniques that expand the structural and biological diversity of compound libraries. Dynamic combinatorial chemistry is an innovative technology with the capacity for supporting the shift from focussed to diverse compound libraries. This application seeks funding to refine dynamic combinatorial chemistry into an effective drug discovery tool.Read moreRead less
