Summary
Golden staph still causes significant human infections and resistance to antibiotics is an ever growing problem with this bacteria. This project will determine how resistance to some antibiotics is also changing the bacteria to promote persistent, difficult to treat infections. The insights from this study will help understand evolution of this bacteria, and help design new strategies for management.

Improvement of anthracycline chemotherapy by enhancement of apoptotic responses and tumour targeted activation. Improved outcomes for anthracycline anticancer chemotherapy is of clear benefit to the nation. Tumour-localised treatment is expected to lead to improved responses, reduced side-effects and improved quality of life while rational selection of drug combinations is expected to enable treatment of tumours that were previously resistant to anthracyclines. With an aging population in Austra ....Improvement of anthracycline chemotherapy by enhancement of apoptotic responses and tumour targeted activation. Improved outcomes for anthracycline anticancer chemotherapy is of clear benefit to the nation. Tumour-localised treatment is expected to lead to improved responses, reduced side-effects and improved quality of life while rational selection of drug combinations is expected to enable treatment of tumours that were previously resistant to anthracyclines. With an aging population in Australia the incidence of cancer is predicted to rise dramatically - improved treatment outcomes and better use of chemotherapeutics will be of obvious national benefit. The development of new tumour-targeted agents is the subject of joint Intellectual Property between Australia and the USA, offering potential economic benefit. Read moreRead less
Tumour localisation and enhancement of anthracycline anticancer activity. The anthracyclines are one of the most widely used anticancer agents today. If the cytotoxicity of these agents can be localised to tumour cells, or their activity improved, then this will result in improved response rates, less side-effects and an improved quality of life for many patients for whom anthracycline treatment is an important part of their therapy. This will result in enormous national/community benefit to an ....Tumour localisation and enhancement of anthracycline anticancer activity. The anthracyclines are one of the most widely used anticancer agents today. If the cytotoxicity of these agents can be localised to tumour cells, or their activity improved, then this will result in improved response rates, less side-effects and an improved quality of life for many patients for whom anthracycline treatment is an important part of their therapy. This will result in enormous national/community benefit to an aging Australian population that is becoming increasingly more prone to cancer. Read moreRead less
Anticancer drug development: Enhancing the anticancer activity of mitoxantrone. Many cancer sufferers may benefit from this work if we are able to develop more active derivatives of mitoxantrone, or develop procedures to inhibit the repair of DNA lesions induced by mitoxantrone. This may result in therapies with improved response, reduced drug dosage and/or reduced side-effects. Because this work may result in one or more patents, and possibly commercialisation with Australian (and overseas) pha ....Anticancer drug development: Enhancing the anticancer activity of mitoxantrone. Many cancer sufferers may benefit from this work if we are able to develop more active derivatives of mitoxantrone, or develop procedures to inhibit the repair of DNA lesions induced by mitoxantrone. This may result in therapies with improved response, reduced drug dosage and/or reduced side-effects. Because this work may result in one or more patents, and possibly commercialisation with Australian (and overseas) pharmaceutical companies, there are potential commercial benefits to Australia. The "discovery" aspect of this work may also identify other cellular responses to mitoxantrone (ie specific genes which are re-expressed) and this may also reveal new targets to further enhance the activity of this drug.Read moreRead less
Molecular basis for the synergistic potentiation of anthracycline anticancer agents by formaldehyde-releasing prodrugs. AIMS: The overall aim is to develop a full understanding of the molecular basis for the synergistic activation of Adriamycin (and other anthracycline anticancer agents) by formaldehyde-releasing prodrugs such as AN-9.
SIGNIFICANCE: Because Adriamycin is currently one of the most widely used anticancer agents, and this activity has the potential to be dramatically enhanced by t ....Molecular basis for the synergistic potentiation of anthracycline anticancer agents by formaldehyde-releasing prodrugs. AIMS: The overall aim is to develop a full understanding of the molecular basis for the synergistic activation of Adriamycin (and other anthracycline anticancer agents) by formaldehyde-releasing prodrugs such as AN-9.
SIGNIFICANCE: Because Adriamycin is currently one of the most widely used anticancer agents, and this activity has the potential to be dramatically enhanced by the concurrent use of formaldehyde-releasing prodrugs, a biochemical understanding of these processes will provide the basis to exploit this synergy to provide improved treatment outcomes (eg, lower drug doses,reduced side-effects, improved activity against drug-resistanct tumours etc).
EXPECTED OUTCOMES: The long-term outcome of this project is commercialisation to develop products for clinical use based on this synergy (eg, drug/prodrug combinations) and ultimately the development of tumour-directed therapy to yield a tumour-localised anticancer response.Read moreRead less
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. We have discovered a group of compounds that inhibit picornaviral RNA polymera ....Novel target of amiloride analogues - picornaviral RNA polymerase.

One of the important aspects evolving in this new era is the design of strategies that enable identification of global protein-protein interactions, defined by the Human Proteome Organisation as the interactome. This, the apoE interactome in human plasma project, will identify novel interactions between plasma proteins and apoE, which is a lipid-binding protein genetically linked to age-related diseases affecting more than 500,000 Australians. This project will therefore provide scope for novel treatments and early detection of disease, namely cardiovascular and Alzheimer's disease.Read moreRead less
