Summary
Pioneering work by CSIRO scientists has identified specific peptide motifs in the DNA replication machinery of bacteria that are critical for the correct functioning of the organism. In collaboration with CI Alewood potent (Kd ~ nM) lead compounds that inhibit bacterial DNA replication have been designed and synthesised.

In collaboration with CI Alewood potent (Kd ~ nM) lead compounds that inhibit bacterial DNA replication have been designed and synthesised. Through the application of a number of novel bioinformatics approaches to the analysis of the complete genome sequences of bacteria, the key sites of interaction of a number of protein families (DNA synthesis and repair enzymes) with the beta subunit of bacterial DNA Polymerase III have been identified. The nature of the sites, and preliminary experimental data, suggests that the approach will be generally applicable to all species of bacteria. In addition a wide range of novel assays for the identification of inhibitors of the interaction of proteins with the beta subunit have been developed. In this proposal we wish to demonstrate that our in vitro nanomolar inhibitors of the beta subunit can inhibit bacterial cell growth. The development program proposes to develop methods and strategies to gain bacterial cell entry of inhibitors of the interaction of proteins with the beta subunit of bacterial DNA Polymerase III. Proof of concept will be demonstrated by inhibition of bacterial cell growth. Stable compounds with good binding characteristics and able to be taken up by cells will be developed based on structure-function assay results, structural studies and modelling of inhibitors bound to the target. Antimicrobial activity of compounds will be demonstrated in standard FDA approved NCLLS (National Centre of Clinical Laboratory Standards USA) tests. Spectrum of activity will be demonstrated by testing compounds against bacterial species representative of the range of pathogenic organisms in standard FDA assays.Read moreRead less
Novel Silver Nanoparticle Coatings For The Prevention Of Infection Of Biomedical Implants And Devices

National Health and Medical Research Council
Funding Amount
$455,305.00
Summary
This project targets infections associated with implants and biomedical devices such as catheters, pacemaker leads, knee and hip implants, by the development and evaluation of coatings delivering antibacterial silver ions. The novel coating method is more uniform and reproducible and can be applied to a wide range of biomedical implants and devices. The novel coatings will be tested for antimicrobial effectiveness and safety using cell and tissue culture methods and animal clinical studies.
Development And Application Of A Pressure-sensing Electropalatograph For The Assessment And Treatment Of Speech Disorder

$200,750.00
Summary
A multidisciplinary team of researchers aim to develop a unique, advanced, computer-based speech device that speech pathologists can use to assess and treat a variety of speech disorders. The device will record the location, timing and pressure of tongue contacts against the roof of the mouth (palate) during speech using innovative sensors embedded in an artificial plate placed over the roof of the mouth. State-of-the-art 3D graphics will be used to display tongue-to-palate contacts to both spee ....A multidisciplinary team of researchers aim to develop a unique, advanced, computer-based speech device that speech pathologists can use to assess and treat a variety of speech disorders.

The Development Of A Cross-strain And Cross-subtype Pre Pandemic Influenza Vaccine Using Savine Technology

Funding Amount
$159,500.00
Summary
The flu vaccines in use today work by inducing antibodies to surface proteins. Flu causes disease every year but occasionally a new strain arises that is distincly differnet from previous strains and can cause wides spread disease and deaths worldwide. Our new approach is to increase the level of T cells that can recognise and kill flu infected cells from all flu strains.
Ocular Implant For The Treatment Of Bacterial Endophthalmitis

Funding Amount
$483,446.00
Summary
We seek to develop an ocular implant for the treatment of bacterial endophthalmitis. The implant will be a small device that can be administered directly to the affected ocular cavity to release an antibiotic in a controlled manner to clear any infection. The implant will erode and leave no residue. It will be produced from a novel drug-polymer conjugate technology that allows polymer devices that comprise >50% drug to be made.
