Summary
Ischaemic stroke, caused by clots that obstruct blood flow to the brain, is the third most common cause of mortality and the leading cause of disability globally. Unfortunately, the only approved therapeutic option is ineffective for a significant proportion of stroke sufferers. This project will develop novel anticoagulants, inspired by molecules produced by blood feeding organisms, for use in more effective and safe ischaemic stroke therapy.
Flaviviral Proteases As Viable Targets For Antiinfective Drugs

Summary
Viruses hijack the machinery and nutrients of cells they infect in order to reproduce. We will study viral enzymes (proteases) essential for virus replication, use fluorescent probes to learn where the viral enzymes hide and act in infected cells, track the passage of drugs aimed at these enzymes, design drugs to block their actions and stop virus replication, and test antiviral activity against Dengue, West Nile, Japanese Encephalitis and Yellow Fever viruses which infect millions of people.
DsbA Foldases From Multidrug Resistant Pathogens As Targets For New Antimicrobials

Summary
Bacteria that cause common human infections, such as cystitis and diarrhoea, are now resistant to many antibiotics. If no action is taken, by 2050 antibiotic resistant infections will kill more people each year than cancer. This project aims to address this global public health crisis by characterising promising new bacterial targets and inhibitors designed to disarm multidrug resistant pathogens. Longer term this work could provide new infection therapies that are urgently needed.
Disruption Of Proteolytic Cascades In The Skin:towards Halting The Atopic March

Summary
There are over 3000 named skin disorders which range in severity from the trivial including acne, to life threatening such as skin cancer. Many skin diseases result from a lack of control over the way the skin maintains itself. Cutting the connections that hold cells together is key to balancing loss of skin cells with their continuous replacement. This project focuses on making compounds to block skin cell shedding with the longer term aim of producing novel drugs to treat skin disease.
Broad Spectrum Inhibition Of An Enzyme Antibiotic Target

Summary
There is a well-documented need to replenish the antibiotic pipeline with new products to combat the rise of drug resistant bacteria. In this project, the enzyme dihydrodipicolinate synthase (DHDPS) is targetted which is essential to bacterial viability. A number of independent but synergistic drug discovery approaches are investigated to develop and test DHDPS inhibitors in the pursuit of a novel class of antibiotics.
Control Of Proteases In Infectious, Degenerative And Cardiovascular Disease

Summary
Proteases are enzymes that control key processes in humans. The research in this program will result in major discoveries in the field of proteases and their inhibitors, with a focus on inflammatory, cardiovascular and degenerative disease. The knowledge gained from this strong foundation of fundamental research will underpin the translational outcomes necessary to combat the debilitating effects of immunological dysfunction, conformational and cardiovascular disease.
An Integrated Approach To Combat Antibiotic Resistance

Funding Amount
$389,120.00
Summary
The development of antibiotics such as penicillin was hailed as one of the great breakthroughs in medicine. However, an increasing number of pathogens have acquired resistance to these drugs. One of the most common resistance mechanisms employed by these pathogens is the use of metal dependent enzymes that promote the degradation of antibiotics. To date, no clinically useful inhibitors for these enzymes are available. In this project, we aim to develop such inhibitors as therapeutic drug leads.
Dissecting Isoform Selectivity Of PI3 Kinase Inhibitors. Uncovering Leads For Rational Drug Design.

Funding Amount
$518,989.00
Summary
The PI3 kinase enzyme controls many functions in cells and in many cases contributes to the onset and progression of diseases such as cancer, thrombosis and inflammatory diseases. Compounds that block PI3 kinase activity may be useful drugs but will need to act specifically to minimize side effects. We aim to understand the way in which inhibitors block the PI3 kinase activity with the belief that this information will allow us to make better drugs.
Regulation Of The Cardiovascular Disease-Associated Protease Inhibitor Cystatin C For Therapeutic Application

Funding Amount
$498,505.00
Summary
Proteases can contribute to atherosclerosis, so they are normally controlled by the endogenous inhibitor, Cystatin C (Cst C). Some conditions cause reduction in Cst C levels and hence disease. On the other hand, excess Cst C can form toxic aggregates. In this project, we will identify mechanisms controlling Cst C expression and aggregation to find therapeutic strategies to treat cardiovascular diseases associated with Cst C.
