Bioactive Peptides as Pharmacological Tools and Novel Drug Leads. Bioactive peptides are produced by all organisms and play numerous critical physiological roles, including in cellular communication, host defence and capture of prey. Peptides have huge potential as tools for studying roles of signalling pathways and as novel drugs due to their high affinity and selectivity for various therapeutically relevant targets. However their use has been limited by poor in vivo stability. This project is ....Bioactive Peptides as Pharmacological Tools and Novel Drug Leads. Bioactive peptides are produced by all organisms and play numerous critical physiological roles, including in cellular communication, host defence and capture of prey. Peptides have huge potential as tools for studying roles of signalling pathways and as novel drugs due to their high affinity and selectivity for various therapeutically relevant targets. However their use has been limited by poor in vivo stability. This project is focused on studying structural features of a range of peptides and their contributions to both activity and to resistance against degradation, with the aim to develop stabilised bioactive peptide sequences for in vivo applications, allowing the full potential of peptides as drugs to be realised.Read moreRead less
Making peptides orally bioavailable. Bioactive peptides are exceptionally useful molecules, however to fully realise their exciting applications key limitations need to be overcome: they can't be delivered orally and they do not last long in the body. This project aims to develop a molecular tag that can dramatically enhance both the oral absorption and time in the body of a peptide. This will include identifying the key elements of the tag required for function, the breadth of peptide cargoes i ....Making peptides orally bioavailable. Bioactive peptides are exceptionally useful molecules, however to fully realise their exciting applications key limitations need to be overcome: they can't be delivered orally and they do not last long in the body. This project aims to develop a molecular tag that can dramatically enhance both the oral absorption and time in the body of a peptide. This will include identifying the key elements of the tag required for function, the breadth of peptide cargoes it can be applied to and the mechanisms underlying this technology. The outcomes of this project will facilitate the future development of peptides for biotechnology, pharmaceutical and veterinary applications.Read moreRead less
Understanding sub-cellular systems at the atomic level. By extending the range of biomolecular systems that can be modelled computationally at the atomic level the project will enable important biomedical processes such as how bacterial toxins penetrate cell membranes and how protein hormones transmit signals into cells to be understood in unprecedented detail.
The mechanism of membrane disruption by antimicrobial peptides. Bacterial resistance to antibiotics is a growing crisis in modern medicine. Antibacterial peptides from Australian frogs represent a new class of potent and selective antibacterial agents. Understanding how these peptides kill bacteria but not vertebrate cells could lead to the design of new drugs for pharmaceutical and/or clinical purposes.
