Glutathione Transferase-derived Compounds As Therapeutic Agents

Summary
Inhibition of cardiac calcium ion channels may be an effective new way of improving heart performance in patients with heart failure. This project will investigate how a glutathione transferase enzyme inhibits calcium ion channels in the heart and if small fragments of a muscle specific glutathione transferase can be used to specifically modify cardiac ryanodine receptor function. These fragments will provide the basis for the development of a new therapeutic approach.
Development Of Peptide-based Scaffolds For Intracellular Cancer Targets

Funding Amount
$1,479,836.00
Summary
The overall aim of this project is to develop peptide-based drugs that are able to cross cell membranes and inhibit specific targets inside cells leading to more effective, safer and cost effective drugs for cancer. One potential outcome of the project will be new drug leads to treat melanoma and leukemia that are likely to be less toxic, more potent and less likely to develop resistance than current treatments.
Development Of Next Generation Drugs For Chronic Myeloid Leukaemia

Summary
Chronic myeloid leukaemia (CML) is one of the four most common types of leukaemia. With current therapies, 15–20% of patients newly diagnosed for CML will die in the next five years, and it is therefore vitally important to discover new treatments. The aim of this project is to develop a new generation of drugs to treat CML based on new approaches (i.e., different type of molecules and different binding site) that can combat the resistance acquired to the current treatments.
We aim to develop a new class of cholesterol-lowering drugs by blocking the interaction between a protein in the blood called PCSK9 and its receptor, which is implicated in cholesterol absorption. We will do this by designing small stable peptides (mini proteins) that mimic part of the receptor and have the potential to interfere with the normal PCSK9 binding process. These drugs should be less expensive and potentially less immunogenic than competing therapies based on antibodies.
Peptides (mini proteins) have outstanding potential as new drugs for cancer, pain and many other diseases, but their potential has not been realised so far because peptides tend to be unstable in the body. I have discovered a new class of peptides that are ultra-stable and have very favourable pharmaceutical properties. I will use these peptides to develop a new generation of drugs that are more potent and with fewer side effects than traditional drugs.
G protein-coupled receptors are proteins that exist on every human cell, where they sense, and respond to environmental stimuli. Because of their importance they are targeted by drugs to treat many diseases. However little is known about how drugs activate these receptors and this has hindered new drug development. I use state-of-the-art technology to determine how drugs activate receptors and develop new methods for drug discovery. This work will have major impact on the Pharmaceutical industry
Discovery And Development Of Better Pain Treatments

Summary
Many forms of pain remain poorly treated, leading to significant quality of life and economic losses. This Program grant will discover and characterise new peptides from cone snails and spiders that modulate specific channels in nerves that are critical to the transmission of pain signals to the brain. Using advanced chemical and structural approaches, promising leads will be optimised for potency and stability and evaluated in disease and pathway-specific models of pain to establish their clini ....Many forms of pain remain poorly treated, leading to significant quality of life and economic losses.
