Throughout our lives cells must die and be replenished. One way multicellular organisms remove unwanted cells is through a process called programmed cell death. This process eliminates redundant, damaged or infected cells by a program of cell suicide. We are studying the underlying molecular mechanisms of this cell suicide in order to design new pharmaceuticals to treat illnesses caused by a disruption in programmed cell death.

One way multicellular organisms remove unwanted cells is through a process called programmed cell death. This process eliminates redundant, damaged or infected cells by a program of cell suicide. We are studying the underlying molecular mechanisms of this cell suicide in order to design new pharmaceuticals to treat illnesses caused by a disruption in programmed cell death. The fine balance between living and dying cells must be maintained and if this balance is lost then disease may result. A reduced level of cell death may result in cancers while too many dying can contribute to degenerative diseases such as Alzheimer's disease and stroke. Currently many of these diseases do not have effective treatments. We will determine the three-dimensional structures of key proteins involved in programmed cell death and use this information to design drugs that can interfere with the molecular processes involved in signalling cell death. Such drugs may prove useful new therapies in a wide range of diseases caused by a breakdown in the biochemical paths to cell death.Read moreRead less
Epilepsy is one of the most common chronic neurological disorders; it affects 1% of the world’s population, yet about 1 in 3 patients fail to achieve seizure control with current drugs. We will improve the properties of small molecules (drugs) that specifically target the GTPase activity of the enzyme dynamin, to reduce seizure effect in the brain by a novel mechanism. We will optimize and pre-clinically test these future chemical entities as potential anti-epileptic drugs.
Centre Of Research Excellence In Medicines Intelligence

National Health and Medical Research Council
Funding Amount
$2,500,000.00
Summary
The NHMRC Centre of Research Excellence in Medicines Intelligence is a co-ordinated research program that will accelerate the development and translation of evidence on prescribed medicines use and outcomes for regulators and payers. The CRE is perfectly placed to embrace the national ‘call to action’ from the Health Minister's recent announcement to establish Quality Use of Medicine Safety as a National Health Priority.
In 2013 there were ~200 million clinical cases of malaria, causing ~600,000 deaths. All antimalarial drugs are now associated with malaria parasite resistance. Thus, new therapies are urgently needed, including new drugs to prevent this disease. We have made the exciting discovery that an existing antimalarial drug can kill malaria parasites in a unique, previously unknown, manner. Here, we will investigate how this occurs and develop new drug candidates for malaria prevention.
Structure-based Design Of Novel Therapeutics For Multi-drug Resistant Neisseria Gonorrhoeae

Summary
Multiple drug resistance (MDR) in bacteria represents one of the most intractable problems facing modern medicine. The recent superbug, MDR-Neisseria gonorrhoeae (MDR-Ng), causes the sexually transmitted infection gonorrhoeae. A multi disciplinary team with expertise in structural biology, medicinal chemistry and bacteriology will establish a comprehensive knowledge base aimed at developing new antibiotics to treat MDR-Ng by targeting a bacterial protein virulence factor.
Development Of Small Molecule Modulators Of Apoptosis

Summary
Cancers rely on the deregulation of key cellular pathways. Along with biological and genetic tools, small molecules are powerful probes to understand these mechanisms. During the course of this research program, we will develop new and drug-like molecules that reinstate the cell death process to combat malignancies. This research will bring important advances for potential chemotherapies and create probes to better understand the biology of programmed cell death processes.
Developing Novel Anti-cancer Agens By High Throughput Chemical Screens For Small Molcules That Modulate The Pro-survival

Summary
Cancer is the second commonest cause of deaths in our community. Unfortunately, treatment often fails or causes unwanted side effects. This proposal seeks to discover and develop a novel class of anti-cancer drugs that act by directly activating programmed cell death (apoptosis). The Bcl-2 proteins are key regulators of cell death and by exploiting knowledge about these prime targets for cancer therapy, we aim to discover drugs that are potentially of considerable medical and commercial value.
Sugar transporters in coral symbiosis and origin of parasitism. We aim to identify how symbiotic algae feed sugar to their coral hosts. Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef.

Corals need this algal sugar to exist, but no one knows how it is transferred, so understanding this crucial mechanism is hugely significant. The first benefit of this research will be a fundamental understanding about how two organisms (algae and coral) cooperate to build habitats like the Great Barrier Reef. We also aim to explore whether coral/algal cooperation paved the way for the origin of parasitism. The second key outcome will be to identify the precise molecular mechanism that allowed parasitism to arise. This will benefit us through understanding the origins of important diseases such as human malaria and related infections of livestock and wildlife.
