Many applications in medical science and drug development depend on our ability to determine the 3D structures of proteins, protein assemblies and protein-ligand complexes. This project will develop novel lanthanide-binding tags and crosslinking agents that can be coupled to unnatural amino acids introduced into proteins with advanced protein chemistry techniques. These new tools will facilitate the collection of structure restraints by nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) and mass spectrometry, which are needed to generate accurate models of proteins and their complexes with other molecules. Major beneficial outcome will include an increase in the number of protein targets amenable to rational drug design and improved methods for generating new drug leads.Read moreRead less

This project aims to establish a tool to accelerate lead generation from very small molecules. This will shift the paradigm in the identification of small molecules that can serve as lead compounds for the development of specific probes or drugs. This project offers a new strategy to rapidly generate lead compounds from a library of compound fragments. The new approach is expected to facilitate identification and development of new lead molecules, drawing on advances made in the field of fragment-based lead discovery, which is increasingly used in the pharmaceutical industries. The tools developed can also be applied for imaging of biological processes. By developing new technologies, the project should deliver intellectual property with potential for commercialisation.Read moreRead less
Asymmetric Synthesis of Chiral Phosphines, Arsines, and Stibines. There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides.

There are now chiral phosphine-transition metal catalysts that rival enzymes in their efficiency for the asymmetric synthesis of important chiral drugs, fragrants, cosmetics, nutrients, vitamins, and pesticides. This project is aimed at a generalised asymmetric synthesis of the critical components of these enzyme mimics, notably enantiopure chiral phosphines, but also chiral arsines and stibines, by a highly innovative approach that involves novel six-electron phosphenium, arsenium, and stibinium cations that are themselves stabilised by chiral phosphines so that chemical breeder reactions are possible. The use of chiral auxiliaries from the natural pool and from biotechnology will also be investigated.Read moreRead less
Quantum-chemical design of stereoregular polyphosphines for nanowires. In this project we will be designing and producing stereoregular polyphosphines that can self-assemble gold and silver complexes that mimic the molecular architectures of DNA and certain proteins.

Whilst Australia has a world-class profile in organotransition metal chemistry, main-group chemistry is under-represented, despite the enormous technological importance of materials based on these elements. In addition to the fundamental breakthrough science to be explored, the project will provide a training vehicle for 5 young scientists in both main group and organometallic chemistry. The target compounds involve an essentially unique marriage of the fields of main-group and transition metal chemistry to provide complex nano-architectures based on the modular interconnection of metals and non-metals by carbon wires at the molecular level - nanoscopic counterparts of macroscopic circuit components.Read moreRead less

Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals.

Metal-boron bonding holds enormous technological importance due to the emergence of boron-based metal-mediated synthetic transformations that access a diversity of high value-added fine chemicals. Whilst Australia boasts an emergent boron-based fine chemicals industry, no research program into the nature of metal boron bonding exists to provide either fundamental science or advanced training in organometallic boron chemistry. The proposed work offers two distinct national benefits: The maintenance of a discipline in which Australia leads the world (metallaboratranes) and the genesis of one, which whilst intensely studied elsewhere, is notably absent from the Australian science base (low coordinate, unsaturated boron chemistry).Read moreRead less

All molecular metal compounds involve a metal surrounded by a group of electron donors (?ligands?). The design and manipulation of these ligand sets and their interactions with metals (?coordination chemistry?) underpins ALL applications of metals, be they in biological, pharmaceutical, materials or industrial applications. This proposal addresses the diametric opposite - the role-reversal wherein a metal centre acts as an electron donor to a ligand. This rare situation has only recently been firmly established in this research group, but promises to be part of a wider new coordination chemistry, the limits of which will be pursued in the proposed work.Read moreRead less
