Funding Amount
$669,148.00
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.
An Ace Up Their Sleeve: Characterisation Of A Novel Family Of Drug Efflux Systems Represented By The Acinetobacter AceI Exporter

Summary
Chlorhexidine is widely used as an antiseptic in products such as skin washes, soaps, mouthwashes, disinfectants and preservatives. We have recently discovered a novel bacterial protein which pumps chlorhexidine out of bacterial cells to make them resistant to this antiseptic agent. This proposal aims to understand this resistance mechanism and to find inhibitors which could be applied in clinical settings to augment the activity of chlorhexidine.
Non-Haemolytic Friulimicins For The Treatment Of Multi-Drug Resistant Bacteria

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.

Evaluation Of Naturally Occurring Resistance To Direct Acting Antiviral Drugs (DAAs) In Individuals With Acute Hepatitis C Infection

Funding Amount
$333,778.00
Summary
Hepatitis C therapy in the future is likely to involve the use of Directly Acting Antivirals, which offer a better chance of treatment success and shorter treatment courses. The downside to these new agents is the possible development of drug resistance. Studies suggest that drug resistant strains may already exist in some individuals prior to treatment. This study plans to use sensitive methods to examine how common drug resistant strains are in untreated individuals with acute hepatitis C.
Phenotypic Characterization Of Chloroquine Resistance In Plasmodia

Funding Amount
$585,473.00
Summary
In the Asia-Pacific region, vivax malaria is becoming the dominant species of infection. The emergence and spread of chloroquine resistant strains of P. vivax threatens malaria control and elimination efforts. This project aims to elucidate fundamental aspects of chloroquine resistance in non-falciparum malaria and identify novel therapeutic options. We will develop novel tests that will help national malaria control programs to monitor declining activity of standard anti-malarial drugs.
Novel Octapeptin Antibiotics Targeting Extremely Drug Resistant 'superbugs'

Funding Amount
$946,024.00
Summary
The World Health Organization (WHO) has identified antimicrobial resistance as one of the three greatest threats to human health. Many clinicians worldwide have already been confronted with the reality of infections caused by extremely drug resistant (XDR) bacterial 'superbugs' resistant to all available antibiotics. This project aims to develop safe and efficacious octapeptin antibiotics for the treatment of life-threatening infections caused by problematic XDR ‘superbugs'.
Polymyxin-like Lipopeptide Antibiotics Of The Future

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.
Defining The Mechanisms Of Action For Ozonide Antimalarials

Funding Amount
$668,152.00
Summary
Deadly malaria parasites have emerged that are resistant to all classes of approved drugs. Ozonides are a new class of medicines recently approved for malaria, and provide a much-needed treatment option for multi-drug resistant infections. However, the mode of action and potential for cross-resistance is poorly understood. This project will use modern analytical techniques to measure the impact of ozonides on parasite biochemistry to reveal mechanisms involved in drug action and resistance.

Summary
The introduction of targeted therapy for chronic myeloid leukaemia (CML) has resulted in excellent responses for many patients. However, some 30-40% of patients respond very poorly to this therapy and therapeutic advances are urgently needed to improve response in these patients. In order to better treat these poor risk patients we aim, in this project, to develop a greater understanding of their disease, and from this identify specific cellular targets for future drug treatment/combination ther ....The introduction of targeted therapy for chronic myeloid leukaemia (CML) has resulted in excellent responses for many patients.

Summary
Tumours treated by chemotherapy often become resistant to the drugs, leading to relapse and reduced chance of survival. We will study one of the main pathways leading to drug resistance, which could lead to the development of new ways to overcome resistance and improve cancer treatment outcomes.
