Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techn ....Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techniques allow us for the first time to fully investigate this approach which if successful will be applicable to many other helical peptides and therefore could be an important drug development technique.Read moreRead less

Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.

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
Environmentally sustainable asymmetric synthesis: design and development of chiral hydrogen bonding organocatalysts. There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes. These inexpensive, non-toxic, air- and moisture-stable catalysts may prove to be more ....Environmentally sustainable asymmetric synthesis: design and development of chiral hydrogen bonding organocatalysts. There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes. These inexpensive, non-toxic, air- and moisture-stable catalysts may prove to be more efficient, selective and have broader applicability than catalysts based on transition metals. The growing Australian pharmaceutical and biotechnology industries will benefit from the development of these new Advanced Materials and the training provided to young scientists in the sought-after fields of asymmetric synthesis and catalysis.Read moreRead less

Solution Processable, High Dimensional Dendrimers for Plastic Electronics. Microelectronics are present in our everyday life, from numerous chips in our vehicles to our mobile telephones; and the list is almost infinite. The electronics used today are limited to rigid surfaces, and are incompatible for the next generation of technology such as rollable displays and radio frequency identification cards.

The electronics used today are limited to rigid surfaces, and are incompatible for the next generation of technology such as rollable displays and radio frequency identification cards. This proposal describes the development of a new class of high performance flexible electronic inks that could be used in the next generation of microelectronics. There is a huge commercial interest in these electronic ink materials and this market is projected to be $7.7 billion by 2012. The proposed electronic inks address issues with current materials such as processability, performance and reproducibility.Read moreRead less

Linking chemical synthesis with protein discovery to reveal key biological pathways. The project aims to pioneer a chemical biology technology to deliver a much better understanding of key molecules that regulate diseases such as cancer.
