Recent developments such as the complete sequence of every malaria gene provides an unparalleled opportunity to use a number of powerful new techniques in biology to identify vulnerabilities in the parasite that may be targeted. Members of the team include Professor von Itzstein who was responsible for the design of the anti-flu drug Relenza, Professor Ross Coppel who is a pioneer in the application of molecular biology to the study of malaria, and Drs Cooke and Plebanski, exciting and talented young scientists who already have made highly significant and important contributions to our understanding of how malaria parasites function and cause disease. Success in this research program has the capacity to save millions of lives each year by preventing the deadly toll of this important human scourge.Read moreRead less
We aim to develop a new class of cholesterol-lowering drugs by blocking the interaction between a protein in the blood called PCSK9 and its receptor, which is implicated in cholesterol absorption. We will do this by designing small stable peptides (mini proteins) that mimic part of the receptor and have the potential to interfere with the normal PCSK9 binding process. These drugs should be less expensive and potentially less immunogenic than competing therapies based on antibodies.
Design And Delivery Of Peptide-based Anti-cancer Grb7 Inhibitors

Funding Amount
$603,126.00
Summary
The Grb7 protein is overproduced in many types of cancer cells and plays a role in cancer cell growth and spread. The current proposal builds upon the discovery of a peptide-based Grb7 inhibitor that has anti-cancer activity. This proposal is to prepare more potent inhibitor molecules that can efficiently reach the target cancer cells. Such molecules will be used for the study of Grb7 and for the development of a new Grb7-based anti-cancer drug therapy.
Development Of Peptide-based Scaffolds For Intracellular Cancer Targets
Funder
National Health and Medical Research Council
Funding Amount
$1,479,836.00
Summary
The overall aim of this project is to develop peptide-based drugs that are able to cross cell membranes and inhibit specific targets inside cells leading to more effective, safer and cost effective drugs for cancer. One potential outcome of the project will be new drug leads to treat melanoma and leukemia that are likely to be less toxic, more potent and less likely to develop resistance than current treatments.
Printhotics: A Digital Solution To Optimise Personalised Children’s Orthotic Devices

Funding Amount
$645,205.00
Summary
Ankle-foot orthoses (AFOs) are custom plastic braces worn around the foot and ankle that are crucial for the daily function of children with nerve, muscle and brain disorders. However, AFO usage is limited by significant wait times, poor adherence and a disconnect with patient preferences. My project, Printhotics, will generate novel AFO designs and production methods based on a concurrent discovery pipeline of co-design, 3D scanning, machine learning, and 3D printing.
Structure-based Design Of Inhibitors Of Oxidative Protein Folding In Enterobacteriaceae.

National Health and Medical Research Council
Funding Amount
$523,540.00
Summary
Antibiotic resistance represents a major public health problem. For gram-negative bacteria in particular, the situation is increasingly bleak, with the accumulation of resistance to existing drugs and few if any new drugs in the pipeline. We are using structure-based drug design to develop novel strategies for the treatment of gram-negative bacterial infections.
Venoms To Drugs: Characterizing The Molecular Interactions Between Venom Peptides And Ion Channels With A View To Rational Drug Design
Funder
National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
The conventional approach to drug development is reaching a state of crisis as it is producing fewer new drugs at increasing cost. A promising alternative is to harness the rich and diverse chemistry of venom peptides. This project aims to understand the mechanism by which venom peptides achieve their pharmacological activity. This knowledge is essential for venom-based drug design for treating diseases ranging from nervous systems disorders, stroke, chronic pain and psychiatric illnesses.

However, there are still a number of hurdles that need to be overcome before this source of promising pharmaceuticals can fulfil their vast potential. One of the biggest challenges in the development of peptides and proteins as drugs is overcoming their poor stability in the human body. The broad aim of this research proposal is to develop a novel strategy that provides therapeutically promising peptides and proteins the ability to resist the body s natural degradation pathways so they are able to reach their biological target. To develop this strategy we will use the recently discovered peptide hepcidin as a model system. Hepcidin is the major iron-regulatory hormone in the human body and incorrect levels of this hormone result in either iron overload (haemochromatosis), when there is not enough hepcidin produced by the body, or anemia of inflammation when there is too much hepcidin. The development of hepcidin-based therapeutic agents to treat these conditions has the potential to have significant impact as it has been estimated that up to 1 in 300 Australians are affected by haemochromatosis during their lifetimes. Unfortunately, unmodified peptides, like hepcidin, are of limited therapeutic value due to their poor stability within the human body. This research proposal describes the development of stabilised hepcidin analogues with the potential of being useful drug leads for the treatment of haemochromatosis.Read moreRead less
Exploitation Of Bacterial Transcription Initiation As A Target For New Antimicrobials

Summary
Antibiotic resistant infections from 'superbugs' are a major health problem. We will exploit information we have gathered on the machinery that copies genetic information into a message to discover chemical compounds that can be used for the development of new antibiotics with a novel mechanism of action.
