The mechanism of membrane disruption by antimicrobial peptides. Bacterial resistance to antibiotics is a growing crisis in modern medicine. Antibacterial peptides from Australian frogs represent a new class of potent and selective antibacterial agents. Understanding how these peptides kill bacteria but not vertebrate cells could lead to the design of new drugs for pharmaceutical and/or clinical purposes.

Distributed facility for fragment based drug discovery:
The facility aims to provide researchers with the ability to generate small molecules that modulate therapeutically and biologically important protein targets. Fragment-based drug design (FBDD) provides a rational approach to generate such biologically active compounds. The facility is designed to allow researchers throughout Australia to access the necessary infrastructure to undertake FBDD projects against a range of biologically important targets. The facility aims to enable access to high-throughput nuclear magnetic resonance spectroscopy and surface plasmon resonance, and to generate the capacity for automation in chemical synthesis and sample preparation to expedite the development of novel bioactive molecules. The development of better approaches to hit development may benefit many researchers in Australia employing FBDD.Read moreRead less
Understanding Multidrug Resistance In Cancer: Identification Of The Substrate And Inhibitor Binding Sites In P-glycoprotein

$284,343.00
Summary
Cancers expressing the multidrug transporter P-glycoprotein (P-gp) are resistant to chemotherapy. The clinical impact of P-gp is so large that the National Cancer Institute (USA) “profiles” all anticancer drugs for transport by P-gp, primarily because the mechanism of drug binding and transport by P-gp is unknown. The aim of this proposal is to understand the molecular details of how drugs bind to and interact with P-gp, a major step in our understanding of P-gp mediated chemotherapy resistance.
Natural product scaffolds: an approach to privileged structures. Based on the fact that nature has provided approximately 50 per cent of current drugs, the purpose of this project is to identify scaffolds that are critical for the biological interactions. The expected outcome is to build libraries based on the scaffolds and identify new privileged structures for application in drug discovery.

The Vevo 2100 micro-ultrasound plus LAZR photoacoustic imaging platform: The Vevo/LAZR ultrasound/photoacoustic imaging facility will allow researchers to achieve multiple outcomes: to visualise and quantify, non-invasively, tissue and molecular structures; the movement and behaviour of cells; and the delivery patterns of administered imaging dyes and nanoparticles in mouse models and reconstructed tissues. This will enable researchers to obtain anatomical, functional, physiological and molecular data simultaneously and in real-time, with resolution down to 40 micrometres. This will translate into both user efficiency and laboratory cost effectiveness, but more significantly is expected to result in greater understanding of fundamental mechanisms regulating the body's cell and tissue functions.Read moreRead less

Summary
General anaesthetics are a mainstay of modern medicine, but have a small safety margin, requiring skilled anaesthetists for their safe use. There is growing evidence that general anaesthetic exposure may have long-term effects on brain function in both newborns and the elderly. This project will provide a detailed molecular description of anaesthetic action and specificity. It will provide the basis for designing new anaesthetics that are safer, both immediately and for long-term brain function.
