Epilepsy is one of the most common chronic neurological disorders; it affects 1% of the world’s population, yet about 1 in 3 patients fail to achieve seizure control with current drugs. We will improve the properties of small molecules (drugs) that specifically target the GTPase activity of the enzyme dynamin, to reduce seizure effect in the brain by a novel mechanism. We will optimize and pre-clinically test these future chemical entities as potential anti-epileptic drugs.
Phenotypic Characterization Of Chloroquine Resistance In Plasmodia

Funding Amount
$585,473.00
Summary
In the Asia-Pacific region, vivax malaria is becoming the dominant species of infection. The emergence and spread of chloroquine resistant strains of P. vivax threatens malaria control and elimination efforts. This project aims to elucidate fundamental aspects of chloroquine resistance in non-falciparum malaria and identify novel therapeutic options. We will develop novel tests that will help national malaria control programs to monitor declining activity of standard anti-malarial drugs.
Development Of Fragment Hits Into Effective Antimalarials; Targeting Malaria Eradication

Funding Amount
$676,798.00
Summary
We have used a novel method that samples the diversity of natural products with a small sub-set of compounds, and observed direct interaction between these compounds and proteins important in the malaria parasite life cycle. This project will develop these identified active compounds towards the goal of producing a drug to fight stages of the malaria parasite’s life cycle that are not targeted by currently available antimalarial drugs.
Discovery Of New And Better Treatments For Human African Trypanosomiasis

Summary
Sleeping sickness, or human African trypanosomiasis, is present in 36 countries where there are 60 million people at risk of infection, with 50,000-70,000 new cases and 48,000 deaths per annum. Transmitted by the bite of the tsetse fly, this disease is caused by the protozoan parasite Trypanosoma brucei, and without treatment, death is inevitable. We have discovered some compounds that weakly inhibit T.brucei and the aim of this project is to make them potent enough to become drug candidates.
Novel Octapeptin Antibiotics Targeting Extremely Drug Resistant 'superbugs'

Funding Amount
$946,024.00
Summary
The World Health Organization (WHO) has identified antimicrobial resistance as one of the three greatest threats to human health. Many clinicians worldwide have already been confronted with the reality of infections caused by extremely drug resistant (XDR) bacterial 'superbugs' resistant to all available antibiotics. This project aims to develop safe and efficacious octapeptin antibiotics for the treatment of life-threatening infections caused by problematic XDR ‘superbugs'.
Polymyxin-like Lipopeptide Antibiotics Of The Future

Summary
Polymyxins are now being clinically used as the ‘last-line’ therapy for infections caused by multidrug-resistant Gram-negative ‘superbugs’. For the first time our novel approach will interface chemistry and biology of the polymyxins with the purpose of creating a new generation of safer and more efficacious polymyxin antibiotics.
A New Class Of Inhibitors For The Treatment Of Tuberculosis

Summary
Tuberculosis (TB) remains a major cause of mortality and morbidity worldwide, with 1.3 million deaths annually. Some strains of the TB bacterium are resistant to all available drugs. We have identified novel chemical structures that display potent and specific activity against pathogenic mycobacteria. In this proposal we will develop optimised derivatives with more potent activity against mycobacteria, assess their stability and toxicity and determine their mode of action.
Mechanism Of Action And Targeting Of Hexokinase II In Glioblastoma

Summary
Deaths from the brain cancer, glioblastoma, are as common as from the skin cancer in Australia. For most patients diagnosed with glioblastoma there is no realistic possibility of cure or even survival beyond a few years. We propose to understand and target glioblastomas aberrant metabolism of glucose, which may lead to better treatments for this devastating cancer.
Reversing Antibiotic Resistance With Efflux Pump Inhibitors

Funding Amount
$494,174.00
Summary
Antibiotic resistance in dangerous pathogens is one of the greatest threats to human health of the 21st century. The main cause of multidrug resistance is the presence of drug efflux pumps, which remove antibiotics from the bacterial cell thereby lowering the antibiotic concentration inside the cells to sub-toxic levels. We will use our expertise on these efflux pumps and on how to inhibit them to develop compounds that could reverse resistance and restore the activity of antibiotics.
Further Development Of The Clinical Potential Of H2 Relaxin

Summary
The hormone relaxin mediates cardiovascular and kidney changes during pregnancy. These important functions have led to its current use in clinical trials for the treatment of acute heart failure, a condition affecting millions of patients worldwide. However, there is an urgent need for a longer lasting form of relaxin for prolonged treatment of patients. Our studies will focus on understanding the blood breakdown of the peptide to lead to the design of longer lasting relaxin analogues.
