Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications.

The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exceptionally stable and resistant to enzyme digestion. The big question is ?How and why does Nature produce circular proteins?" Increasing our knowledge of why circular proteins have evolved will facilitate their applications in drug design and in the development of novel insecticides.Read moreRead less

National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and m ....National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and molecular computers. The magnetochemical projects described here, that require the new equipment being sought, are fundamental in nature but will provide the underpinning of future nanomagnetic materials.Read moreRead less
Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; a ....Selectively targeting cancer and infectious disease with fragment-based drug discovery. Finding better compounds as starting points is one of the major challenges for drug discovery research. Fragments are small, weak binding molecules that can be upsized into drug leads with better properties when compared to starting with larger molecules. This project addresses two weaknesses of current fragment based drug discovery (FBDD) methods: first, the limitations associated with screening fragments; and second, the quality of commercial fragment libraries. This project anticipates that the findings will establish a commanding role for both mass spectrometry and three-dimensional fragments in advancing FBDD approaches. It also expects to identify fragments with favourable development prospects towards the next generation of therapeutics.Read moreRead less

The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved. Pre-requisites for cage design are that they be stable and soluble in aqueous media, and be resistant to anionic ligand exchange at the cluster surface. The targeted metals are based on good attenuation at high (100 to 140 keV) and low X-ray (less than 30 keV) energies, and the possibility of high stability and low toxicity.Read moreRead less

Proteases are pivotal enzymes during birth, life, ageing and death of all organisms. Proteases regulate most physiological processes by controlling protein activation, synthesis and turnover and are essential for replication and spread of viruses, bacteria and parasites that cause infectious diseases. Blockbuster drugs and diagnostics already target a few proteases. Australians have made innovative contributions individually to understanding and regulating these enzymes. However this initiative aims to network their efforts by value-adding to the current protease research through promoting national and international collaborations to improve our understanding of biology, and encourage exploitation of proteases/inhibitors/receptors for pharmaceutical and industrial applications.Read moreRead less
