Molecular probes for pancreatic cancer. Cancer has overtaken heart disease as the main cause of premature death in Australia. Currently one in two men and one in three women are diagnosed with cancer during their lifetime. Pancreatic cancer is the fourth leading cause of cancer death in Australia, and the current lack of effective therapies results in a 1 year survival of just over 10%, and a 5 year survival of less than 5%. This project aims to identify and produce new compounds with novel mech ....Molecular probes for pancreatic cancer. Cancer has overtaken heart disease as the main cause of premature death in Australia. Currently one in two men and one in three women are diagnosed with cancer during their lifetime. Pancreatic cancer is the fourth leading cause of cancer death in Australia, and the current lack of effective therapies results in a 1 year survival of just over 10%, and a 5 year survival of less than 5%. This project aims to identify and produce new compounds with novel mechanisms of action that will facilitate our understanding of pancreatic carcinogenesis and provide the basis for the development of new therapeutic strategies. Australians diagnosed with pancreatic cancer in the future may directly benefit from the results of this work.Read moreRead less
An Integrated Approach Towards Development of Highly Specific Chemotherapeutics. Many diseases are caused or can be treated by modifying the activities of particular enzymes. Molecules that affect enzymatic activities have potential as therapeutic agents. A successful approach to the discovery of new drug molecules is to design them based on very detailed knowledge of how the target enzyme works. In this project, a highly motivated team of scientists will use state of the art instruments and the ....An Integrated Approach Towards Development of Highly Specific Chemotherapeutics. Many diseases are caused or can be treated by modifying the activities of particular enzymes. Molecules that affect enzymatic activities have potential as therapeutic agents. A successful approach to the discovery of new drug molecules is to design them based on very detailed knowledge of how the target enzyme works. In this project, a highly motivated team of scientists will use state of the art instruments and their combined creativity to understand the intimate details of how one large group of enzymes work. The enzymes selected are the bimetallic hydrolases, many of which are associated with disorders including osteoporosis, mental illnesses, cystic fibrosis and various types of cancer.Read moreRead less
Generation of peptidomimetic surfaces for biomaterials applications. Biomedical implants are increasingly being used for the treatment of a variety of ailments.

Biomedical implants are increasingly being used for the treatment of a variety of ailments. This project will significantly contribute to the development of these bioengineered constructs, by introducing an innovative method for tailoring the nature of the surface of these materials with structures that mimic the response of biological surfaces. This technology has the potential to promote favourable interactions of cells with biomedical implants, and an initial targeted application will be to use these bioengineered constructs in the treatment of preventable blindness and severe visual impairment, afflictions which affect over 180 million individuals worldwide.Read moreRead less
Anti-Cancer Natural Products: Total Synthesis and Biological Evaluation of Lasonolide A and Analogues. One in three men and one in four women in Australia will be diagnosed with cancer before they reach 75. Cancer is a leading cause of death within this country with 28% of deaths each year due to this disease. Although there have been advances in the treatment of various forms of cancer there remains a pressing need for new therapies with improved potency, selectivity and reduced side effects. T ....Anti-Cancer Natural Products: Total Synthesis and Biological Evaluation of Lasonolide A and Analogues. One in three men and one in four women in Australia will be diagnosed with cancer before they reach 75. Cancer is a leading cause of death within this country with 28% of deaths each year due to this disease. Although there have been advances in the treatment of various forms of cancer there remains a pressing need for new therapies with improved potency, selectivity and reduced side effects. This project will provide new compounds of potential clinical use in the treatment of cancer, thereby aiding the large population of Australians who will be affected by this disease. Furthermore, the new advanced materials produced by this project will aid in the study of biochemical processes involved in cancer.Read moreRead less
Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobili ....Mobility of water in cartilage as a probe of molecular structure and function. Clinical diagnosis of early-stage osteoarthritis is difficult, and most patients are not diagnosed until a substantial degradation of cartilage has occurred as a result of the disease. This research will study the interaction between different components of articular cartilage and investigate, how this interaction can be exploited for the development of reliable and non-invasive techniques of cartilage imaging. Mobility of water molecules is a potent indicator of the microscopic structure of the cartilage scaffold. We will use this fundamental biophysical relationship to measure the internal architecture of collagen fibres; observe the changes effected by mechanical load; and distinguish between healthy and osteoarthritic cartilage.

Understanding of biochemical processes in living organisms is central to biological research and drug discovery. At present, the field suffers from a chronic paucity of adequate observation methods. The proposed project represents an interdisciplinary effort to create approaches for real-time monitoring of complex cellular chemistries. This work will deliver novel technologies for use in diagnostics and drug development. It will provide vital information on the changes in cellular processes induced by malignant transformation, viral infection and aging. This work will generate both health and economic benefits for the community and have a positive impact on the international visibility of Australian biomedical research.Read moreRead less
Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a cru ....Structure-based design of anti-osteoporotic drug leads: an integrated approach. One of the major consequences of Australia's aging population is that age-related diseases, such as osteoporosis, are increasing. Apart from the significant human suffering caused by this disease, there is an immense financial burden on the community, patients and their families. Current treatments for osteoporosis are often ineffective and also have major side-effects. An enzyme has been identified which plays a crucial role in the progression of this disease by increasing the rate of bone-thinning. We will make compounds to slow down this enzyme. This project will provide the basis for the future development of new and improved drugs to treat osteoporosis.Read moreRead less
Graded Biomaterial for Articular Cartilage Replacement.
