Improving Synthetic Methodology To Prepare Pre-clinical Analogues Of Human Insulin

Funding Amount
$457,708.00
Summary
The glucose regulatory hormone, insulin, remains the only treatment for type I diabetes and up to 30% of type II diabetes, both of which are among the world’s fastest growing chronic diseases today. Because insulin, if taken orally, would be broken down quickly, it has usually been given by injection. This project will develop novel chemical methods for the efficient preparation of novel insulin therapeutics with improved stability and oral bioavailability for prolonged treatment of patients.
Development Of Carbohydrate Based Self-adjuvanting Vaccine Delivery System

Funding Amount
$311,647.00
Summary
The world is in a need for effective vaccines for the treatment/prevention of a range of currently occurring diseases. The aim of this project is to develop sugar/lipid-based delivery systems by revolutionary new chemo-enzymatic technology. Expected outcomes of the project will be numerous biologically active vaccine candidates and novel technologies which will lead to effective therapeutic products.
Chronic pain is a significant global health, economic and social problem, with the annual economic burden estimated at approximately $40 billion in Australia. My research will focus on the discovery and structure-function of venom peptides (trivially called toxins) from cone snails and spiders plus other Australian venomous creatures that modulate sodium and calcium channels in peripheral pain and associated pathways and optimise these for clinical development.
Developing Novel Peptide-based Therapeutics And Technologies To Mitigate Fibrosis

Funding Amount
$1,161,383.00
Summary
Fibrosis (tissue scarring) is an unmet medical problem that adversely affects both human health and medical devices. It causes organ (e.g. heart, kidney) failure leading to death. Fibrotic encapsulation causes medical device (e.g. surgical mesh) failure. Our team has discovered a peptide, B7-33, that mitigates fibrosis in the short-term. Our IDEAS grant aims to develop long-acting B7-33 therapies and, to employ long-acting B7-33 mimetics in anti-fibrotic compositions for surgical meshes.
This project will unleash the potential of peptide drugs by overcoming their final barrier to widespread use, their synthesis. Plants naturally produce ultra-stable cyclic peptides. We will co-opt their machinery to produce in seeds, two drug leads that have potential as treatments for prostate cancer and chronic neuropathic pain. As an �organic� drug source, seeds have the potential to improve patient compliance and low-tech production systems will allow technology transfer to third-world natio ....This project will unleash the potential of peptide drugs by overcoming their final barrier to widespread use, their synthesis.

Membrane-active Antibiotics Against Multi-drug Resistant Gram Negative Bacteria
Funder

Funding Amount
$942,299.00
Summary
We are now threatened by bacteria that are resistant to ALL antibiotics. However, there is a new paradigm: antibiotics inspired by nature that attack the membrane of bacteria. This project will re-engineer peptides from lugworms, horseshoe crabs, scorpions and spiders that are part of nature’s ancient defence against bacteria, to identify new antibiotics to combat infections in humans.
Next Generation Relaxin Molecular Probes And Therapeutics
Funder
National Health and Medical Research Council
Funding Amount
$763,845.00
Summary
The peptide hormone relaxin is poised to be the first new treatment for acute heart failure in more than 40 years. However, like other therapeutic peptides, it has a very short duration of action due to its rapid clearance by the body. My work will utilize powerful medicinal chemistry methods to develop new analogues of relaxin that have much longer action by complexing it with sugar or making relaxin polymers. I will also produce smaller relaxin analogues that will be cheaper to manufacture.
