An Investigation of Novel Sialylmimetics as Inhibitors of Rotavirus. Rotavirus causes severe gastroenteritis in infants worldwide. Over 125 million cases of diarrhoea and 800,000 deaths annually are attributed to rotavirus. The process that enables this debilitating and sometimes fatal disease to infect cells is poorly understood. This project aims to produce a range of unique chemical entities that will provide information about the way rotavirus infects cells.

Over 125 million cases of diarrhoea and 800,000 deaths annually are attributed to rotavirus. The process that enables this debilitating and sometimes fatal disease to infect cells is poorly understood. This project aims to produce a range of unique chemical entities that will provide information about the way rotavirus infects cells. The chemical compounds produced in this study will be evaluated for their ability to prevent rotavirus from infecting cells.

The development of a rapid diagnostic test for heparanase activity. Heparanase is an enzyme that has been implicated in a number of disease states such as cancer, arthritis, multiple sclerosis and other inflammatory diseases. Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this a ....The development of a rapid diagnostic test for heparanase activity. Heparanase is an enzyme that has been implicated in a number of disease states such as cancer, arthritis, multiple sclerosis and other inflammatory diseases. Characterisation of this enzyme has been slow, due in part to the lack of a reliable direct activity assay. Using a multi-disciplinary approach, this project seeks to establish a rapid assay that will provide easy determination of heparanase activity. Furthermore, this assay could provide a useful diagnostic tool in a clinical environment that would allow for the rapid assessment of these diseases, their progression and indeed response to therapy.Read moreRead less
Carbohydrates and Carbohydrate-Recognising Proteins as Drug Discovery Targets. The significance and roles of carbohydrates in many biological processes, in particular those processes associated with disease, is now well-recognised. These new directions have captured the attention and imagination of not only academic research groups across the world, but also pharmaceutical and biotechnology companies and has restimulated their interest in the pursuit of carbohydrate-based drugs and drugs against ....Carbohydrates and Carbohydrate-Recognising Proteins as Drug Discovery Targets. The significance and roles of carbohydrates in many biological processes, in particular those processes associated with disease, is now well-recognised. These new directions have captured the attention and imagination of not only academic research groups across the world, but also pharmaceutical and biotechnology companies and has restimulated their interest in the pursuit of carbohydrate-based drugs and drugs against carbohydrate-recognising proteins critical in disease processes. The current application seeks to use some of this information to faciliate the discovery of novel carbohydrate-based chemical entities as inhibitors of the spread of some cancers and diseases caused by pathogenic microorganisms.Read moreRead less
Design, Synthesis and Biological Evaluation of Rotavirus Inhibitors. Rotavirus causes, particularly in children under 5 years of age, significant loss of life worldwide. Over 400,000 children under 5 years of age per annum die as a result of rotavirus infection. Australia records over 10,000 hospitalisations per annum due to rotavirus infection. This project aims, using structure-based drug design techniques, to develop inhibitors of a rotavirus protein that is essential in its lifecycle.

This project aims, using structure-based drug design techniques, to develop inhibitors of a rotavirus protein that is essential in its lifecycle. These inhibitors may lead to the development of useful drugs to treat rotavirus infection and may reduce significant loss of life caused by this deadly virus.Read moreRead less
Investigation of novel sialic acid mimetics to target the spread of cancer. The mortality rates for many cancers afflicting the world's population are extremely high and these rates are consistent with the Australian experience. It is generally accepted that colon cancer, and cancers as a whole, are a significant healthcare issue and have immense socioeconomic impact. Alternative treatments preventing the spread of cancers would be of very significant benefit. This fellowship will provide the ....Investigation of novel sialic acid mimetics to target the spread of cancer.

It is generally accepted that colon cancer, and cancers as a whole, are a significant healthcare issue and have immense socioeconomic impact. Alternative treatments preventing the spread of cancers would be of very significant benefit. This fellowship will provide the opportunity for the discovery and development of such treatments that are based on the processes that utilise carbohydrates to facilitate the spread of tumours.Read moreRead less
Development of Multivalent Hyaluronan Derivative Therapeutics. Over-expression of the hyaluronan receptor CD44 has been identified at pathological sites of diseases such as cancer, psoriasis, arthritis and asthma. The research described in this proposal aims to develop novel therapeutic compounds which target CD44 whilst eliciting a therapeutic index.

The research described in this proposal aims to develop novel therapeutic compounds which target CD44 whilst eliciting a therapeutic index. The design of these new therapeutics is based on a template structure which incorporates known cytotoxic or anti-fungal agentsas well as hyaluronan, a naturally occurring carbohydrate, ubiquitous in nature.Read moreRead less
Regulation of cell surface sialylation by targeting the CMP-sialic acid transporter and sialyltransferase: Towards the development of anti-metastatic agents. The mortality rates for many of the cancers afflicting the world's population are mirrored in Australia, particularly colon cancer.

The mortality rates for many of the cancers afflicting the world's population are mirrored in Australia, particularly colon cancer. It's generally accepted that colon cancer, and cancers as a whole, are a significant healthcare issue in this country, representing a major challenge to biomedical researchers and healthcare professional. The economic and social impact is immense, placing a huge strain on the healthcare system, as well as on the families affected. Any alternative treatment reducing cancer metastasis would be of enormous national and international benefit. It's believed that the significant studies outlined in this proposal, which are based on exciting preliminary data, will make a sizeable contribution to achieving this goal.Read moreRead less
Development of carbohydrate-based drug delivery systems. Chronic skin disorders affect 5% of the population. Treatment is challenging and long term because these disorders are chronic and unpredictable. Currently the most potent therapies for psoriasis are administered systemically. Long term usage of these therapies causes side effects such as kidney or liver damage. This proposal describes a new approach to the topical treatment of psoriasis where potent drugs are linked to a hyaluronan sca ....Development of carbohydrate-based drug delivery systems. Chronic skin disorders affect 5% of the population. Treatment is challenging and long term because these disorders are chronic and unpredictable. Currently the most potent therapies for psoriasis are administered systemically. Long term usage of these therapies causes side effects such as kidney or liver damage. This proposal describes a new approach to the topical treatment of psoriasis where potent drugs are linked to a hyaluronan scaffold molecule and are directly applied to the diseased tissue. Advantages of this approach include targeted drug delivery mediated by hyaluronan receptor processes and potential amelioration of the observed drug toxicities.Read moreRead less
