Chronic pain is a significant global health, economic and social problem, with the annual economic burden estimated at approximately $40 billion in Australia. My research will focus on the discovery and structure-function of venom peptides (trivially called toxins) from cone snails and spiders plus other Australian venomous creatures that modulate sodium and calcium channels in peripheral pain and associated pathways and optimise these for clinical development.
Novel Fluorogenic Probes For The Selective Detection Of Pathogenic Bacteria

Summary
Current methods for the detection of multi-resistant organisms either require expensive instrumentation and expert analysts or are simple, but require 24-48 hours for bacterial identification. The ideal surveillance method would be cost effective, rapid, reliable, and simple to perform. This project aims to prepare a range of fluorescent substrates for incorporation into growth media which will then be evaluated for the specific identification of individual multi-resistant organisms, e.g. MRSA.
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.
Evaluation Of Novel Pyrrolo/Iminoquinone Antimalarial Compounds

Summary
The development of new antimalarial drugs is an unmet global health priority. In this project we will investigate novel compounds that have been found to display promising in vitro antimalarial activity. We will modify these compounds to make them more drug-like, and assess their efficacy in vivo using malaria animal models. These studies have the potential to identify compounds that may result in a new therapy for malaria, the worlds' most significant tropical infectious disease.
Membrane-active Antibiotics Against Multi-drug Resistant Gram Negative Bacteria

Funding Amount
$942,299.00
Summary
We are now threatened by bacteria that are resistant to ALL antibiotics. However, there is a new paradigm: antibiotics inspired by nature that attack the membrane of bacteria. This project will re-engineer peptides from lugworms, horseshoe crabs, scorpions and spiders that are part of nature’s ancient defence against bacteria, to identify new antibiotics to combat infections in humans.
New methodology for the manufacture of opioid pharmaceuticals and the discovery of novel opiate receptor ligands. Semi-synthetic opiates are important analgesic agents and are used in the treatment of alcohol and opiate dependence. This project will focus on the application of new, greener and more efficient methods for the preparation of these medicinal agents.
Diene regenerative Diels-Alder reactions to access chemical scaffolds. This project aims to develop methods and strategies that allow rapid access to biologically active chemical scaffolds based on natural products. Natural products and their analogues are vital starting points for drug discovery as they provide unique chemical diversity. Without efficient methods for their production, it is not possible to exploit this diversity.

This project aims to develop methods and strategies that allow rapid access to biologically active chemical scaffolds based on natural products. Natural products and their analogues are vital starting points for drug discovery as they provide unique chemical diversity. Without efficient methods for their production, it is not possible to exploit this diversity. This project will develop an efficient, modular strategy that will allow the preparation of a wide range of chemicals in a timely manner. Restoring access to potent biologically active materials is expected to generate chemical probes and lead to molecules that could have biomedical value.Read moreRead less
Dissecting catalysis and inhibition of a unique endo-acting mannose-processing glycosidase. Defects in the attachment of carbohydrates to proteins are a hallmark of diseases such as cancer and viral infection. This project will dissect the molecular details of the bond-making and breaking steps that occur during the synthesis of glycoproteins assisting in the development of innovative new drugs.

Summary
Chronic pain is a major global health problem that currently affects over three million Australians. There are few drugs available for treatment of chronic pain and most have significant side-effects. Individuals lacking a particular type of ion channel known as Nav1.7 are completely insensitive to pain, but are otherwise normal. Block of this channel therefore appears to be an ideal avenue for pain relief. This project aims to produce selective Nav1.7 blockers that can be used as analgesics for ....Chronic pain is a major global health problem that currently affects over three million Australians.

LRH-1 is a protein that is inappropriately present in cancers of the breast and other tissues. It causes cancer cells to divide and multiply, and therefore it is important to block its activity. There are, however, no treatments available that block LRH-1. This proposal brings together a team of researchers with broad experience. We will use high throughput technologies to identify and characterize novel LRH-1 inhibitors, and demonstrate their efficacy in reducing the growth of cancer cells.
