Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin m ....Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin molecule that will be designed to provide critical information on the location and structure of gibberellin receptors. Screening of the probes for potential effectiveness will be determined initially by the measurement of alpha-amylase produced in a standard barley aleurone assay.Read moreRead less
Chemical listening devices: Novel sensors targeting the clandestine manufacture and transport of illicit drugs and explosives. There can be no doubt that protecting Australia's borders from the dual threats of terrorism and illicit drugs is of paramount importance to continuation of our well-being and way of life.

There can be no doubt that protecting Australia's borders from the dual threats of terrorism and illicit drugs is of paramount importance to continuation of our well-being and way of life. Our chemical sensors are simple hand-held or remote chemical listening sensors, which will have the ability to sense the presence of characteristic chemical vapours associated with explosives and illicit drugs. The simplicity and low cost of the chemical listening allows for installation at key locations -e.g. transport hubs, shipping containers, airports etc as well as placement within clandestine drug laboratories.Read moreRead less
Structural And Functional Analysis Of A Cancer-linked Co-regulator Complex

Funding Amount
$729,571.00
Summary
We seek to understand the mechanisms by which genes are switched on and off throughout our lifetime. A number of multi-component protein machines are involved in this process but their make-up and mechanism of action is not understood. We will investigate the structure and function of one of these machines that has been strongly linked to cancer.
Domino Approaches to Polycyclic Natural Products. Organic molecules are the basis of all known life forms. The majority of our medicinal agents are organic molecules. Organic molecules are made up of atoms, connected together by bonds. Usually, these molecules are constructed by making one bond at a time. We are trying to make this laborious job quicker and more efficient by forming lots of bonds at once. Research of this kind is the basis for the development of new pharmaceuticals. Australia do ....Domino Approaches to Polycyclic Natural Products. Organic molecules are the basis of all known life forms. The majority of our medicinal agents are organic molecules.

We are trying to make this laborious job quicker and more efficient by forming lots of bonds at once. Research of this kind is the basis for the development of new pharmaceuticals. Australia doesn't have many people who are able to do this kind of thing. We will train four to six people in this area of research.Read moreRead less
New Cascade Routes to Biologically Important Molecules. This research involves the development of short and efficient syntheses of several different classes of biologically active molecules using cascade reactions: spectacular events in which many chemical bonds are formed. Two distinct types of cascade reactions will be investigated and naturally-occurring molecules with antineoplastic, anti-immunosuppressive, antiviral and antimalarial activities will be prepared. These new, expedient routes a ....New Cascade Routes to Biologically Important Molecules. This research involves the development of short and efficient syntheses of several different classes of biologically active molecules using cascade reactions: spectacular events in which many chemical bonds are formed. Two distinct types of cascade reactions will be investigated and naturally-occurring molecules with antineoplastic, anti-immunosuppressive, antiviral and antimalarial activities will be prepared. These new, expedient routes allow the preparation of a wide range of structurally-related analogues; an important prerequisite for the preparation of libraries of compounds for biological evaluation. Along the way, important information about the chemical reactivity patterns of a newly-prepared, fundamental class of hydrocarbon molecules will be obtained.Read moreRead less
Platelet Glycoprotein Proteolysis: Novel Mechanisms And Risk Factors
Funder
National Health and Medical Research Council
Funding Amount
$441,473.00
Summary
Platelets are the richest source of amyloid precursor protein (APP) in the body. Platelet ADAM10 regulates both the expression and function of the major platelet collagen receptor GPVI, and protective APP processing. Coagulation protein Factor X has a role in activation of ADAM10. This activation is disrupted in blood that has been treated with direct oral anticoagulant (DOAC) rivaroxaban. This grant will investigate the implications for people taking rivaroxaban on regulation of APP and GPVI.
Nitroxide-containing scaffolds for controlling biofilm-related infections. Bacterial biofilms are a major problem in healthcare systems around the world as they cause persistent and chronic infections, including those associated with medical implants and cystic fibrosis. This project aims to develop new chemical approaches to deliver nitroxides at surface interfaces and in microparticles to facilitate long term control over biofilm growth. It is expected that these functionalised scaffolds will ....Nitroxide-containing scaffolds for controlling biofilm-related infections. Bacterial biofilms are a major problem in healthcare systems around the world as they cause persistent and chronic infections, including those associated with medical implants and cystic fibrosis. This project aims to develop new chemical approaches to deliver nitroxides at surface interfaces and in microparticles to facilitate long term control over biofilm growth. It is expected that these functionalised scaffolds will represent a breakthrough in the field and will have a profound impact by reducing infection rates associated with medical devices and improving airway clearance in cystic fibrosis patients.Read moreRead less

This research program aims to develop more efficient methods for the chemical synthesis of organic substances: the materials that make up all known life forms, our medicines, and many designed materials. This research involves primarily the invention of new, enabling science. Specifically, we are trying to develop new and very general strategies to make organic compounds selectively and more efficiently than before. A more efficient chemical synthesis means less waste, lower energy consumption and less environmental impact. Research of this kind is absolutely essential for the development of new medicines and materials. Australia lags behind many of the world's developed countries in this very important area of endeavour.Read moreRead less
