Summary
Alcohol dependence is a major cause of mental and physical illness in Australia. Current medications for treating this condition are of limited effectiveness. This project will investigate the ability of the hormone oxytocin to reduce alcohol abuse and alcohol craving and to reverse the brain damage that alcohol causes. The project will also develop new medications, based on oxytocin, but with more powerful and longer lasting effects.

Therapeutic Approaches To Circumvent NO• Resistance In The Type 2 Diabetic Heart And Vasculature

Funding Amount
$563,337.00
Summary
Type 2 diabetes (T2D) is Australia’s fastest growing chronic disease, affecting almost 2 million Australians (who face poor cardiovascular health outcomes). We have discovered an exciting new avenue that may potentially more effectively counteract heart and blood vessel disorders in T2D patients in an acute cardiovascular emergency, of substantial clinical importance.
Biased Allosteric Modulators Of Metabotropic Glutamate Receptors: Novel Therapeutic Targets For CNS Disorders

Funding Amount
$611,534.00
Summary
Metabotropic glutamate receptor 5 (mGlu5) is a major therapeutic target for depression and schizophrenia. The proposed studies will improve our understanding of how drug-like chemicals interact with mGlu5 and therefore change the activity of these receptors and in turn the activity of brain cells leading to therapeutic effectiveness. The research undertaken in this program will allow us to be smarter in developing new mGlu5 drugs that are both effective and have minimal side effects.
ROLE OF A DOWN SYNDROME-RELATED PROTEIN IN STROKE OUTCOME
Funder
National Health and Medical Research Council
Funding Amount
$931,302.00
Summary
This project will test whether a gene called DSCR1, which is present at a higher level in Down Syndrome individuals, might play a protective role in the outcome after stroke. We will identify the cells and molecular pathways that are involved in this protective effect in mice, with a longer term view of applying this information to the development of new types of targeted therapies for clinical stroke.
Understanding Allosteric Modulation And Biased Signalling At Family B GPCRs

Funding Amount
$428,065.00
Summary
Family B GPCRs are therapeutic targets for drugs treating osteoporosis, hypercalcaemia, Paget’s disease, type II diabetes and are being actively pursued for other diseases that represent major global health burdens. Despite huge financial input, there are no orally available drugs that act on these receptors. This speaks to a lack of mechanistic understanding of how they work. My research focuses on addressing this question and how to exploit these receptors to design and identify better drugs.
Towards The Rational Design Of Calcium Sensing Receptor Allosteric Modulators For The Treatment Of Osteoporosis And Calcium Handling Disorders
Funder

Funding Amount
$741,390.00
Summary
Drugs that target the human calcium sensing receptor can be too strong or too weak, resulting in side effects or lack of efficacy. This proposal thus seeks to establish whether the strength of drug activity can be rationally altered and exploited to treat different disease states by fine-tuning CaSR activity in a disease-specific manner.
Blood-Brain Barrier Penetrating Antisense Therapy For Spinal Muscular Atrophy
Funder

Funding Amount
$635,005.00
Summary
Spinal muscular atrophy (SMA) is a genetic disease caused by the deficiency of a protein known as survival motor neuron.This results in the degeneration of motor neurons (nerve cells controlling muscles) leading to progressive muscle weakness, paralysis, and eventual death. Currently, there is no known cure for SMA. The aim of proposed research is to develop gene-modifying molecules that prevent degeneration of motor neuron and extend the life-span of mice as a potential therapy for SMA.
The Structural Basis For Biased Agonism At The Glucagon-like Peptide-1 Receptor
Funder

Funding Amount
$872,536.00
Summary
The glucagon-like peptide-1 receptor plays an essential role in nutrient-regulated insulin release, and is a major target for therapeutic treatment of type 2 diabetes. The binding of different drugs to this receptor can promote distinct signalling profiles inside the cell that can lead to different physiological outcomes. Understanding the mechanistic basis for this will provide a framework to enable rational design of novel, better and safer therapeutics for the treatment of diabetes.
Understanding The Structural Basis For Family B G Protein-coupled Receptor Function
Funder
National Health and Medical Research Council
Funding Amount
$745,082.00
Summary
G protein-coupled receptors (GPCRs) are the largest family of cell surface proteins that enable communication from external signals to the inside of cells of the body. Family B GPCRs are a therapeutically important subclass of these receptors and they play crucial roles in bone and energy homeostasis, cardiovascular control and immune response. This grant will uncover fundamental knowledge on how these receptors work, and will enhance future development of therapeutics.
Understanding Mechanisms Of Allostery And Biased Agonism At The Adenosine A1 Receptor

Funding Amount
$603,033.00
Summary
This project focuses on an important protein found in the heart. Drugs that activate this protein can protect the heart against damage that occurs after a heart attack, but they all have undesirable side effects. We have discovered a new class of molecule that can protect the heart without these side effects. We now seek to understand how these compounds work at the molecular level. This knowledge can facilitate the design of safer medicines for the treatment of cardiovascular disease.
