Summary
We are developing a new antibiotic, called friulimicin, to combat the ïsuperbugsÍ that cause serious infections in hospitals and the community. We will optimize the drug to target MRSA (methicillin resistant Staphylococcus aureus) VRE (vancomycin resistant enterococci) and DRSP (drug resistant Streptococcus pneumoniae). We will also investigate how the drug can be used for treatment of lung infections such as pneumonia, where the antibiotic can work much better than existing drugs against resist ....We are developing a new antibiotic, called friulimicin, to combat the ïsuperbugsÍ that cause serious infections in hospitals and the community.

Polymyxin-like Lipopeptide Antibiotics Of The Future

Funding Amount
$335,323.00
Summary
Polymyxins are now being clinically used as the ‘last-line’ therapy for infections caused by multidrug-resistant Gram-negative ‘superbugs’. For the first time our novel approach will interface chemistry and biology of the polymyxins with the purpose of creating a new generation of safer and more efficacious polymyxin antibiotics.
The Development Of Novel Antibacterials Targeting Clostridium Difficile Infections

Funding Amount
$750,546.00
Summary
Clostridium difficile is a bacterium associated with infections in the gut which may result in mild to severe diarrhoea and inflammation of the colon. These infections are an increasing problem for hospitalised patients in the US, the EU and Australia. We have been very successful in the past at developing new drugs to treat external infections caused by resistant strains of bacteria, for example, golden Staph. We now aim to develop our drugs to treat C. difficile infections in the gut.
Lipopeptide Antibiotics For XDR Gram-negative Infections

Funding Amount
$994,897.00
Summary
The polymyxins are a drug class considered to be a last-resort treatment option for multidrug-resistant (MDR) and extremely drug resistant (XDR) Gram-negative infections. Unfortunately resistance is rapidly developing against these antibiotics, leaving no effective therapies and resulting in patient death. This project aims to develop an antibiotic with superior spectra of action and improved safety profiles compared to the polymyxins, with activity against polymyxin-resistant bacteria.
Development Of Antimalarial Histone Deacetylase Inhibitors

Funding Amount
$573,676.00
Summary
Human histone deacetylases (HDACs) are enzymes clinically validated as targets for cancer chemotherapy. Different HDAC enzymes are important for survival of infectious organisms, such as protozoan Plasmodium parasites that cause malaria. This project will develop promising drug leads that kill the parasites without damaging human cells through preclinical studies in mice towards a future clinical trial for the treatment of malaria in humans.
Development Of Small Molecules For The Treament Of Colon Cancer

Funding Amount
$684,379.00
Summary
Colon cancer remains one of the leading causes of cancer related deaths in Australia and in the developed world. Despite improvements in prevention and therapies, there remains a considerable need for efficacious therapeutic options. We have identified a lead compound inhibiting the growth of cancer cells. We will progress this series further toward clinical trials and aim to provide patients with a new orally available molecule with potent activity against colon cancer.
From Lead Compounds To Potential Therapeutics: Drugs To Treat Clostridium Difficile Infections

Funding Amount
$523,460.00
Summary
Clostridium difficile infection (CDI) attacks the gut resulting in diarrhoea and inflammation of the colon. It is classified as the number one antibiotic-resistant bacterial threat in the USA where there are 500,000 cases of CDI and 30,000 deaths. CDI is an increasing problem for hospitalized patients in the US, the EU and Australia. Our recent NHMRC funded project established drug leads against CDI and we now require continued studies to develop our drug leads towards marketable therapeutics.
Developing Inhibitors Of An Essential Histidine Kinase In Staphylococcus Aureus

Funding Amount
$578,352.00
Summary
Staphylococcus aureus (Golden staph) has been termed a "superbug" because of its persistent ability to acquire resistance to a wide range of antibiotics. Once considered primarily a hospital-acquired pathogen, many patients are now being infected with antibiotic-resistant Golden staph outside of hospitals. The primary aim of this research program is to develop new antibiotics to treat antibiotic-resistant strains of Staphylococcus aureus and related pathogens.
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.
Development Of Fragment Hits Into Effective Antimalarials; Targeting Malaria Eradication

Summary
We have used a novel method that samples the diversity of natural products with a small sub-set of compounds, and observed direct interaction between these compounds and proteins important in the malaria parasite life cycle. This project will develop these identified active compounds towards the goal of producing a drug to fight stages of the malaria parasite’s life cycle that are not targeted by currently available antimalarial drugs.
