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.

Investigating The Therapeutic Potential Of FTY720 For Human African Trypanosomiasis
Funder
National Health and Medical Research Council
Funding Amount
$653,736.00
Summary
FTY720, is a drug currently used to treat multiple sclerosis, which we have shown is also be able to kill the parasite responsible for African sleeping sickness, Trypanosomes. We aim to identify the target the drug acts on in the parasite to have its affect. Our objective is to improve the activity further by chemical modification to produce a potent, orally available and well characterised, non-toxic drug suitable for preclinical development.
Retargeting The Antibiotic Azithromycin As An Antimalarial With Dual Modality.
Funder
National Health and Medical Research Council
Funding Amount
$773,613.00
Summary
Malaria parasites resistant to first-line treatments continue to spread in South East Asia. New drugs need to be developed urgently to ensure alternative treatment strategies are available. We will retarget the safe and widely used antibiotic azithromycin as an antimalarial with dual modalities against parasite invasion and growth inside the host red blood cell. This strategy has significant potential to increase drug efficacy while reducing the chances for the development of resistance.
Understanding And Targeting Coenzyme A Biosynthesis And Utilisation In Plasmodium Falciparum.
Funder
National Health and Medical Research Council
Funding Amount
$556,114.00
Summary
This grant describes a series of studies designed to understand how the human malaria parasite P. falciparum metabolises vitamin B5, an essential molecule for the parasite. We will also carry out experiments to determine how a new series of vitamin B5 analogues we have developed kill the parasite and aim to start developing these compounds into new and much needed antimalarial medications.
Octapeptin-based Antibiotics Against Multi-drug Resistant Gram-negative Bacteria
Funder
National Health and Medical Research Council
Funding Amount
$767,504.00
Summary
Infectious disease is a leading cause of death, and the emergence of "superbugs" in the community and hospitals is of grave concern. We have resurrected a ‘forgotten’ antibiotic from the 1970s that kills superbugs causing pneumonia, skin and urinary track infections; diseases that cause death and discomfort for thousands of Australians today. We will determine how the original antibiotic works against superbugs, and use this information to design better drugs for the future.
New Antibiotics And Treatment Methods Against Drug-resistant Bacteria
Funder
National Health and Medical Research Council
Funding Amount
$766,468.00
Summary
Infectious disease is a leading cause of death, and the emergence of "superbugs" in the community and hospitals is of grave concern. We are developing new, powerful antibiotics that can kill superbugs using ‘forgotten’ drugs from the 1970s. These will combat bacteria that cause pneumonia, skin and urinary track infections; diseases that cause death and discomfort for thousands of Australians today. We will also develop methods to directly remove bacteria from blood infections.
Potent Lipoglycopeptide Antibiotics Against C. Difficile
Funder
National Health and Medical Research Council
Funding Amount
$750,411.00
Summary
In some people C. difficile bacteria naturally reside in the gut. Other people accidentally ingest spores of the bacteria while they are patients in a hospital or nursing home. Sometimes, broad-spectrum antibiotics used to treat an infection also kill healthy gut bacteria. The gut then becomes overrun with C. difficile, causing diarrhoea and pain, and sometimes death. We will investigate the use of a new potent antibiotic, vancapticin, to kill C. difficle and prevent relapse of infection.
Pharmacological Targeting Via AKT, PTEN, And TGF-beta Pathway Integration Using Novel Therapeutics
Funder
National Health and Medical Research Council
Funding Amount
$634,875.00
Summary
We have identified potentially important interactions of cellular pathways that vary between individual sufferers, but which also provide common molecular targets for novel drug development. Our suite of novel and potent drugs that markedly and selectively inhibit cancer cell growth will be studied to determine if these pharmaceutical agents act to inhibit tumour cell proliferation by targeting common effector molecules of integrated cellular pathways.
Discovering How A Novel Anti-malarial Drug Series Rapidly Kills Parasites
Funder
National Health and Medical Research Council
Funding Amount
$672,971.00
Summary
We have developed a new set of highly potent anti-malarial drugs but we do not know how they work. Identifying how these compounds work is important for improving their effectiveness and safety. We will discover how these drugs kill parasites by using a number of cutting edge methods that could also be useful for discovering how other drugs work. Data generated will progress these compounds along the drug development pipeline which urgently needs a constant supply of new antimalarials.
Targeting Cancer-initiating Cells With DNA Methyltransferase Inhibitors: Single-cell Analysis To Decipher Molecular Mechanisms And Improve Efficacy.
Funder
National Health and Medical Research Council
Funding Amount
$175,000.00
Summary
Certain cancer cells, termed cancer-initiating cells (CICs), have special properties allowing them to drive cancer growth and disease progression. These cells are particularly sensitive to low-dose treatment with drugs called DNA methyltransferase inhibitors. Using cutting-edge "single-cell" technologies this project will determine how these drugs target CICs and identify new ways to increase treatment efficacy. This work will identify new clinical opportunities for prevention of cancer relapse.
Obstructive sleep apnea (OSA) is one of the most common complications of obesity and is independently associated with a reduced quality of life and cardiovascular disease. This project aims to identify the underlying factors linking obesity with OSA by examining how weight loss surgery can improve these factors. These important findings will contribute greatly to our understanding of OSA pathophysiology and are necessary to find better treatments for obesity-associated OSA.
