STRUCTURAL CHARACTERIZATION OF ACTIVE CONSTITUENTS IN PLANT EXTRACTS WITH POTENTIAL FOR THE CONTROL OF OVINE LICE AND PARASITIC WORMS. The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identif ....STRUCTURAL CHARACTERIZATION OF ACTIVE CONSTITUENTS IN PLANT EXTRACTS WITH POTENTIAL FOR THE CONTROL OF OVINE LICE AND PARASITIC WORMS. The control of lice and parasitic worms are two of the major problems currently confronting the Australian sheep industry. Several plant extracts utilized in traditional medicine have shown a remarkable efficacy in the control of these pests in humans. This project will investigate the sheep lousicidal and anthelmintic activity of a number of plants, and identify and chemically characterize the active constituents. This research will lead to the production of more environmentally friendly pest control methods and overcome problems of insecticidal resistance currently facing the industry.Read moreRead less

Summary
A ROBOTIC NMR SPECTROMETER FOR ACCELERATED DRUG DISCOVERY. The aim is to establish a facility that will use a robotic NMR instrument to help in the characterisation of drug-protein interactions and in the discovery of new drugs or agrichemicals. The significance is that with the wealth of new information arising on protein sequences from genomics programs there is an urgent need to accelerate the rate of discovery of ligands that bind to these proteins. Such ligands may provide useful drug lea ....A ROBOTIC NMR SPECTROMETER FOR ACCELERATED DRUG DISCOVERY. The aim is to establish a facility that will use a robotic NMR instrument to help in the characterisation of drug-protein interactions and in the discovery of new drugs or agrichemicals. The significance is that with the wealth of new information arising on protein sequences from genomics programs there is an urgent need to accelerate the rate of discovery of ligands that bind to these proteins. Such ligands may provide useful drug leads or help in defining the function of newly discovered proteins. The outcomes will be new knowledge on protein structure and function, and potentially, new bio-active molecules.Read moreRead less
Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to sy ....Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to synthesise sex pheromones. We propose that understanding the chemical and biochemical steps employed by the flies will allow us to design inhibitors to prevent pheromone production and thus provide a novel, species specific method for controlling fruit flies.Read moreRead less
Development of new herbicides targeting enzymes involved in the biosynthesis of branched-chain amino acids. Modern agriculture is heavily reliant on the use of herbicides. An inevitable consequence of herbicide usage is that resistant weeds will develop. Therefore, there is a continuing need to develop new herbicides to kill these resistant species. Herbicides interact with vulnerable molecular targets in plants, such as photosynthesis or the biosynthesis of certain amino acids. This project wil ....Development of new herbicides targeting enzymes involved in the biosynthesis of branched-chain amino acids. Modern agriculture is heavily reliant on the use of herbicides. An inevitable consequence of herbicide usage is that resistant weeds will develop. Therefore, there is a continuing need to develop new herbicides to kill these resistant species. Herbicides interact with vulnerable molecular targets in plants, such as photosynthesis or the biosynthesis of certain amino acids. This project will attempt to develop new herbicides that act upon two molecular targets that are not exploited by herbicides that are used currently. We will design, synthesize and test a variety of new compounds as potential environmentally-benign herbicides.Read moreRead less
Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that ....Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that contribute to a potent inhibitor and those that are required for it to be effective upon plants. Using this information we will design and synthesis new compounds as potential environmentally-benign herbicides.Read moreRead less
Discovery and applications of circular proteins. The many national benefits that will flow from this program include (i) new knowledge in plant biochemistry, peptide chemistry and protein engineering protected by a strong intellectual property position that will give Australia a competitive edge in relevant biotechnology applications; (ii) the training of a new generation of skilled researchers to drive a sustainable biotechnology sector in Australia; (iii) economic benefits from royalty returns ....Discovery and applications of circular proteins.

Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exce ....Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exceptionally stable and resistant to enzyme digestion. The big question is ?How and why does Nature produce circular proteins?" Increasing our knowledge of why circular proteins have evolved will facilitate their applications in drug design and in the development of novel insecticides.Read moreRead less
