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.

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.

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

Summary
Bioaffinity mass spectrometry infrastructure to identify small molecules binding to therapeutic targets. The development of anti-infective therapies is challenging because the underlying biology and biochemistry of pathogen virulence is not yet completely understood. This mass spectrometer facility will be used to identify small molecules suited for development into new therapies for malaria, tuberculosis and HIV.
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.
Chemical probes for visualising DNA synthesis. This project aims to develop chemical probes to quantify DNA synthesis in complex mammalian and parasite cellular systems in conjunction with image-based technologies. Chemical probes are small molecule reagents that have a profound impact on our ability to answer fundamental questions about biological processes within living cells. The probes will be differentiated from current probes that are toxic or incompatible with state-of-the art imaging. Th ....Chemical probes for visualising DNA synthesis. This project aims to develop chemical probes to quantify DNA synthesis in complex mammalian and parasite cellular systems in conjunction with image-based technologies. Chemical probes are small molecule reagents that have a profound impact on our ability to answer fundamental questions about biological processes within living cells. The probes will be differentiated from current probes that are toxic or incompatible with state-of-the art imaging. The project expects to generate intellectual property with potential for development into commercial products that allow researchers expanded opportunities to study complex biological processes.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.
Understanding allosteric modulation and functional selectivity at G Protein-Coupled Receptors (GPCRs). GPCRs are an important superfamily of proteins that are involved in a myriad of physiological processes and a wide range of serious illnesses. This project seeks to gain a more detailed understanding of new mechanisms of GPCR modulation and function that will be of direct relevance to drug discovery.
Subtype selectivity and functional bias of receptor positive allosteric modulators for understanding models of pulmonary disease. G-protein-coupled receptors (GPCRs) are an important superfamily of proteins that are involved in a myriad of physiological processes and a wide range of serious illnesses. This project seeks to gain a more detailed understanding of new mechanisms of GPCR modulation and function that will be of direct relevance to drug discovery.
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.
Chemical Insights to Peptide Helix-Sheet-Nanofibre Equilibria. We live in an ageing community that is experiencing exponential growth in neurological diseases that require full time carers and place significant burdens on our health system. Many such diseases are caused by (apparently) abnormal folding of proteins that aggregate into insoluble materials. The chemistry behind these processes is not sufficiently well understood to know precisely why the diseases are caused and how they might be tr ....Chemical Insights to Peptide Helix-Sheet-Nanofibre Equilibria. We live in an ageing community that is experiencing exponential growth in neurological diseases that require full time carers and place significant burdens on our health system. Many such diseases are caused by (apparently) abnormal folding of proteins that aggregate into insoluble materials. The chemistry behind these processes is not sufficiently well understood to know precisely why the diseases are caused and how they might be treated. This project will use new strategies to control peptide folding, provide important new information relevant to understanding such processes/diseases, and teach us how to engineer important new biomaterials that can advance nanotechnology.
