Overcoming antibiotic resistance: rapid discovery of new antibacterial drug targets using chemical proteomics. The prevalence of multidrug-resistant bacteria in the community is a critical public health issue and there is an urgent and compelling need for new antibiotics with novel modes of action to combat these deadly superbugs. While antibiotics from nature have long been a mainstay of the pharmaceutical industry, their development as drugs can be challenging as their cellular targets and mod ....Overcoming antibiotic resistance: rapid discovery of new antibacterial drug targets using chemical proteomics. The prevalence of multidrug-resistant bacteria in the community is a critical public health issue and there is an urgent and compelling need for new antibiotics with novel modes of action to combat these deadly superbugs. While antibiotics from nature have long been a mainstay of the pharmaceutical industry, their development as drugs can be challenging as their cellular targets and modes of action are frequently unknown. In this project, innovative chemical proteomics approaches will be used to rapidly identify and characterise the cellular targets and modes of action of both newly discovered and historic antibiotic natural products, thereby overcoming this bottleneck and accelerating the development of next-generation antibiotics.Read moreRead less

Summary
Elucidation and characterisation of the misfolded protein interactome. Correct expression, folding, and clearance of proteins are critical for all cell functions. However, cell stresses and aging can cause protein balance mechanisms to become overloaded, resulting in the misfolding and aggregation of proteins. Understanding the mechanisms by which protein aggregation occurs and how to prevent the process have become major scientific challenges. This project aims to gain unprecedented insights in ....Elucidation and characterisation of the misfolded protein interactome. Correct expression, folding, and clearance of proteins are critical for all cell functions. However, cell stresses and aging can cause protein balance mechanisms to become overloaded, resulting in the misfolding and aggregation of proteins. Understanding the mechanisms by which protein aggregation occurs and how to prevent the process have become major scientific challenges. This project aims to gain unprecedented insights into the interactors, effectors and fate of misfolded protein aggregates within cells, using new, cutting-edge, catalytic-tagging biochemical tools. Critical interactions will be investigated for their roles in protein aggregation cell death, and in whether modulation of the interaction can also mitigate or reverse the process.Read moreRead less

Summary
High-throughput, high resolution protein-peptide sequencing and quantification facility. This facility will enhance the research capability of scientists at The University of Queensland who are using mass spectrometry to elucidate the structures of novel toxins which have the potential to be developed as drugs.
Development of Insulin-like peptide 5 (INSL5) peptide analogues as novel therapeutics. Insulin-like peptide 5 (INSL5) is a naturally-occurring hormone in the body that likely plays a role in the control of appetite. This project aims to develop new molecules based on INSL5 that could be suitable for use as drugs to treat various appetite-related disorders, such as obesity (where patients eat too much) or anorexia (where patients eat too little).
Structure and function of predatory and defensive venoms in cone snails. This project aims to investigate newly-discovered cone snail venoms to accelerate the search for novel bioactive peptides. It was recently discovered that cone snails can rapidly and reversibly switch between distinct venoms in response to predatory or defensive stimuli, implying that defensive and predatory venoms have evolved under separate selection pressures. The project plans to obtain separate predatory and defensive ....Structure and function of predatory and defensive venoms in cone snails. This project aims to investigate newly-discovered cone snail venoms to accelerate the search for novel bioactive peptides. It was recently discovered that cone snails can rapidly and reversibly switch between distinct venoms in response to predatory or defensive stimuli, implying that defensive and predatory venoms have evolved under separate selection pressures. The project plans to obtain separate predatory and defensive venoms and venom duct tissue from individual cone snails to compare and contrast the structure and function of conotoxins evolved for predation versus those evolved for defence, to elucidate the structure and function of these important classes of bioactive peptides.Read moreRead less
Towards the development of orally active antimicrobial peptides with distinctive mode of action. This project aims to design and develop novel antibacterial compounds to address one of humankind's greatest health concerns, that of antibacterial resistance. These will be further modified to make them orally available, thus enhancing their therapeutic and clinical potential.
