Novel target of amiloride analogues - picornaviral RNA polymerase. Picornaviruses cause a range of diseases such as poliomyelitis, meningitis, myocarditis, hepatitis A, neonatal sepsis and common cold. No antiviral treatment is available for these infections. Nearly 50% of antiviral drugs used in medicine are viral polymerase inhibitors; however picornaviral RNA polymerase has been largely overlooked as a drug target.

The Australian economy is gradually expanding its manufacturing base through the development of the nanotechnology and biotechnology sectors. This will lead to production of a more diverse range of elaborately transformed goods. A key contributor to these export opportunities will be the nanotechnology sector since at the present time no country has a real nanotechnology based economy and there are many niche markets available for smaller countries such as Australia. This proposal helps to build quality control and characterisation infrastructure that will facilitate prototyping and design of nanoscale devices and sensors for next generation manufacturing.Read moreRead less
Development of a test bed for molecular memory and molecular photovoltaic devices. The development of nanostructured materials and the devices that utilize them is at the forefront of modern science and technology.

The development of nanostructured materials and the devices that utilize them is at the forefront of modern science and technology. Electrical devices whose functional units are structurally ordered single molecules dominate biochemical processes, especially pertinent ones being photosynthesis and cellular energy production; artificial devices promise new technologies in multi-$B markets such as long-term data storage and renewable solar-energy production. Interfacing molecules with macroscopic interconnects poses a great technological challenge, however, and in this project the underlying basic science will be determined through the formation of molecules into device-accessible functional materials.Read moreRead less

Diseases in which voltage-gated sodium channels are implicated are contributors to morbidity and mortality in the Australian population, and this project promises to provide new leads for the future development of drugs to treat such diseases, in particular analgesics for the treatment of chronic pain. The generation of these leads will entail the development of new approaches to mimicking key regions of peptides and proteins in drug-like molecules. This is a highly interdisciplinary project, spanning structural biology, molecular design, medicinal chemistry, molecular biology and electrophysiology, and the training of PhD graduates with such broad experience represents another national benefit of the project.Read moreRead less

The need for potent low-cost drugs is ever increasing, yet effective ways to screen for new drugs remain elusive. A spectroscopic approach to screening drugs in living cells would seem a logical alternative to chemically based and morphological methods that are the status quo. In this context we are developing methodology to analyse molecular target sites in single living cells for two of the most devastating diseases to afflict human kind, namely malaria and cancer. New ways of rapidly screening drugs in living cells prior to clinical trials will save an enormous amount of time, money and ultimately lives.Read moreRead less
