Voltage-dependent structural changes in voltage-gated sodium channels. This project aims to provide insights into the structural rearrangements experienced by Nav channels, which are key components of animal nervous systems. Voltage-gated sodium (Nav) channels initiate action potentials in excitable cells. They open in response to membrane depolarisation then rapidly inactivate. Eukaryotic Nav channels contain four unique voltage-sensor domains (VSDs) that control how the channel responds to mem ....Voltage-dependent structural changes in voltage-gated sodium channels. This project aims to provide insights into the structural rearrangements experienced by Nav channels, which are key components of animal nervous systems. Voltage-gated sodium (Nav) channels initiate action potentials in excitable cells. They open in response to membrane depolarisation then rapidly inactivate. Eukaryotic Nav channels contain four unique voltage-sensor domains (VSDs) that control how the channel responds to membrane potential changes. Recently reported crystal structures of bacterial Nav channels have greatly advanced the field, but these channels contain four identical VSDs and have different inactivation properties. Thus, much remains to be learnt about the conformational plasticity of eukaryotic Nav channel VSDs. The project plans to use animal toxins to capture eukaryotic VSDs in defined states of the gating cycle for detailed structural analysis using nuclear magnetic resonance and X-ray crystallography.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

Revitalizing facilities for nuclear magnetic resonance in South Australia. Nuclear magnetic resonance (NMR) spectroscopy is the single most powerful spectroscopic tool for determining molecular structure. Our aim is to upgrade NMR infrastructure available to researchers across South Australia with an integrated and complementary array of state-of-the-art spectrometers to diversify usage across a range of disciplines.

Nuclear magnetic resonance (NMR) spectroscopy is the single most powerful spectroscopic tool for determining molecular structure. Our aim is to upgrade NMR infrastructure available to researchers across South Australia with an integrated and complementary array of state-of-the-art spectrometers to diversify usage across a range of disciplines. Replacement of outdated spectrometers will modernise core NMR facilities along with installation of new probes to improve sensitivity and the ability to analyze small sample quantities. Our overall strategy is to maximize capability and minimize duplication, while bringing South Australia's NMR capabilities up to a national and international standard. Read moreRead less

Lasers are indispensable tools for the characterization and photochemical modification of molecular systems. Powerful lasers produce intense bursts of light across the electromagnetic spectrum, from the infrared to the ultraviolet. This versatility allows chemists to observe the dynamical behaviour of single molecules on ultra-fast timescales, to probe the shape of molecules relevant to the action of therapeutic drugs, to explore the characteristics of molecules found in space, and to initiate laser-activated chemical processes in microscopic dimensions to modify sensor surfaces. The proposed laser facility will enable progress in these areas and will help maintain Australia's research edge in nanotechnology and biotechnology.

This project aims to develop molecular materials based on non-precious metals that respond to stimuli, including heat or light, by switching between forms with different properties, such as colour and electrical conductivity. The project expects to deliver enhanced control over the switching characteristics and incorporation of the materials into responsive thin films, ready for integration into devices. These molecular switches are promising for molecular electronics, spintronics and colour-based sensing and display devices. Their fast response time and small component size imply less heat to dissipate and therefore less electricity required for cooling upon implementation in information communications and other technologies.Read moreRead less
