Mixing the jigsaw pieces of natural products: new molecules-new properties. This project aims to examine the capacity of exploiting the bacterial biosynthetic machinery to fast-track access to analogues of natural products. Due to increased drug resistance, new reservoirs of natural products are needed for evaluation as future drugs.

This project aims to examine the capacity of exploiting the bacterial biosynthetic machinery to fast-track access to analogues of natural products. Due to increased drug resistance, new reservoirs of natural products are needed for evaluation as future drugs. Desferrioxamine B will be used as a model natural product to establish the biosynthesis of new analogues in bacterial culture supplemented with unsaturated, fluorinated or deuterated building blocks. The intended outcomes are to deliver advances in methods for generating structurally diverse pools of natural products, new label-free probes, knowledge of natural product biosynthesis, and excellence in training research students in frontier methods in chemical biology and drug discovery.Read moreRead less
Antimicrobial and anti-Leishmanial bismuth compounds and materials. The project aims to develop the bioinorganic and medicinal chemistry of bismuth and related metals to address two global health issues: parasitic infections (principally Leishmaniasis) and antibacterial resistance.

The project aims to develop the bioinorganic and medicinal chemistry of bismuth and related metals to address two global health issues: parasitic infections (principally Leishmaniasis) and antibacterial resistance. Through targeting serious microbial infections, the project will research the chemical, physical, structural and biological properties of bismuth and related metals. The project will form bio-protective materials and surfaces through incorporating bismuth and its compounds into polymer matrices. It will establish the complexes’ chemical biology and toxicology through scrutinising cellular mechanisms, particularly modern metallomic techniques. New compounds developed may address the urgent and significant health issue of antibiotic resistance and help address poorly treated parasitic infections.Read moreRead less

Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesiz ....Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesize chelators and hijack this to bioengineer new classes of chelators. Outcomes include new chelators and advanced knowledge of metal selectivity, with potential environmental and economic benefits arising from recovery of valuable metals. The project will benefit chemical biology research training for real-world applications.Read moreRead less
Sulfoxide Polymers - A New Paradigm in Polymer Design. Low fouling polymers are important for moderating interactions of molecules and particles with cells. In pharmaceutical sciences they are essential tools for extending the pharmacokinetics of dissolved drugs. However, the widely-used low-fouling polymer, poly(ethylene glycol) (PEG) has been recently reported to induce formation of anti-PEG antibodies. Polymeric alternatives to PEG are thus desperately needed. We introduce in this project sup ....Sulfoxide Polymers - A New Paradigm in Polymer Design. Low fouling polymers are important for moderating interactions of molecules and particles with cells. In pharmaceutical sciences they are essential tools for extending the pharmacokinetics of dissolved drugs. However, the widely-used low-fouling polymer, poly(ethylene glycol) (PEG) has been recently reported to induce formation of anti-PEG antibodies. Polymeric alternatives to PEG are thus desperately needed. We introduce in this project super-hydrophilic polymers incorporating sulfoxide groups, mimics of the polar solvent DMSO. The project aims to explore how polymer architecture can enhance biocompatibility and reduce biofouling. The outcome will be a new class of low-fouling polymeric materials with broad application in the biosciences.Read moreRead less
Opening Up Access to L-Sugars through a Synergy of Experiment and Theory. This project aims to address a major bottleneck in the science of carbohydrates by developing the first broad-scope synthetic routes to L-sugars. L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make.

L-sugars are critical components of many biologically and commercially significant molecules, but knowledge of their functional roles is impeded by the fact that most L-sugars are expensive or difficult to make. This project expects to develop expeditious routes to L-sugars via an innovative combination of synthetic and theoretical chemistry. Expected outcomes include a markedly increased capacity to access pure samples of L-sugar-based biomolecules, as needed for studying their biological functions. Significant benefits in the development of vaccines, diagnostics and biomaterials are anticipated.Read moreRead less

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
