New antiparasitics to protect Australian livestock. There is an urgent need for new antiparasitics to treat multi-drug resistant livestock infections. This project aims to explore the bacteria and fungi present in the microbiomes of heavily infected sheep faeces and pastures, challenging them with environmental cues, including those from associated parasites, to stimulate production of defensive chemicals hidden deep within their genomes. Enabled by an integrated pipeline of high throughput anal ....New antiparasitics to protect Australian livestock. There is an urgent need for new antiparasitics to treat multi-drug resistant livestock infections. This project aims to explore the bacteria and fungi present in the microbiomes of heavily infected sheep faeces and pastures, challenging them with environmental cues, including those from associated parasites, to stimulate production of defensive chemicals hidden deep within their genomes. Enabled by an integrated pipeline of high throughput analytical cultivation, molecular networking, and chemical and biological analyses, expected outcomes include an enhanced ability to explore and exploit valuable chemistry hidden within microbial genomes, leading to the discovery of new classes of natural antiparasitic to safeguard livestock.

Antiparastic agents to safeguard Australian livestock. This project will develop new and improved agrochemicals that can be used to treat highly multi-drug resistant parasites that infect Australian livestock, safeguarding animal health and welfare, and improving the economic viability and prosperity of the Australian livestock industry.
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. Desferrioxamine B will be used as a model natural product to establish the biosynthesis of new analogues in bacterial culture supplemented with unsaturated, fluorin ....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. 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

Nuclear magnetic resonance facility for Northern Australia: Nuclear magnetic resonance spectroscopy is a fundamentally and critically important technique in the characterisation of organic, inorganic and biological compounds. Research areas that will be supported by this facility include organometallic chemistry and the development of new materials and analytical sensors; organic photochemistry as applied in synthesis and degradation; and natural products, pharmaceutical, and inorganic chemistry, where multinuclear nuclear magnetic resonance is most important and applicable in drug design, development and delivery.Read moreRead less
Fragment based screening to deliver drugs targeting tuberculosis and the gametocyte and liver stages of Plasmodium. This project will identify natural products that bind to critical proteins in malaria and tuberculosis to discover new ways to treat these diseases.
New antibiotics: engaging microbial chemical diversity. This project will explore Australian microbial biodiversity, to detect, isolate and identify new natural chemicals with potent and selective antibacterial properties. Knowledge of these molecules will inspire and inform the development of new classes of antibiotic, effective against multi-drug resistant infections.
Growing a sustainable new molecular resource. This project will provide access to a unique and unexplored Australian molecular resource pre-programmed by evolution for therapeutic potential. These discoveries will enable important biomedical research and advance the development of new improved drugs that treat a diverse array of human diseases and illness.
Escaping Bio-Assay Guided Isolation: Nature's Tools for Chemical Biology. The project aims to transform the approach to identify novel biologically active compounds that occur in nature. For decades, natural product chemistry has centred on bio-assay guided isolation, but it has become increasingly difficult to isolate novel compounds. While de-replication strategies detect the presence of known compounds using databases, more impact would be achieved by directly detecting novel compounds. Nucle ....Escaping Bio-Assay Guided Isolation: Nature's Tools for Chemical Biology. The project aims to transform the approach to identify novel biologically active compounds that occur in nature. For decades, natural product chemistry has centred on bio-assay guided isolation, but it has become increasingly difficult to isolate novel compounds. While de-replication strategies detect the presence of known compounds using databases, more impact would be achieved by directly detecting novel compounds. Nuclear magnetic resonance (NMR) spectroscopy detects every molecule that has a proton and is quantitative. This project plans to develop a NMR technique to escape bio-assay guided isolation by analysing a fraction library. Biotechnology innovation is dependent on novel compounds to provide new products. Replacing ‘grind and find’ with a technique that never lies would be transformational.Read moreRead less
Pioneering new oxidation catalysis paradigms for organic synthesis. The project aims to deliver highly novel chemical reactions based on previously unforeseen catalyst attributes, The societal impact of catalyst-promoted chemical reactions can be measured by the enormous volume of manufactured goods (eg plastics, pharmaceuticals) based on this technology. Expected project outcomes could be transferred into commercial chemical research and development programs.
Chemically re-engineering bioactive natural products using fragment based drug design. Current drug and agrichemical discovery technologies are under immense pressure to meet the future pharmaceutical and agriculture demand created by population growth. This project will develop a novel technology concept that re-engineers the chemical features of bioactive natural products optimising medicine and agrichemical discovery.
