The information from Human Genome Project is being used to generate molecules with a variety of therapeutic and diagnostic applications. The capability to design, synthesise and manipulate functional molecules that mimic biological processes will underpin many emerging applications. In this project, macrocyclic metal complexes that catalyse the cleavage of phosphate ester bonds in biological molecules will be developed.

Chemistry of the Transport of Nutrient Copper in Biological Cells. Nutrient trace metals such as copper are needed for enzymes by living organisms but are toxic in excess. Defects in copper metabolism cause Menkes and Wilson diseases in humans and there are direct connections to neurodegenerative diseases (eg, Alzheimer, Parkinson, Creutzfeldt-Jakob, motor neuron diseases). It is crucial to understand how healthy cells control toxic but essential copper so that enlightened intervention is possib ....Chemistry of the Transport of Nutrient Copper in Biological Cells. Nutrient trace metals such as copper are needed for enzymes by living organisms but are toxic in excess. Defects in copper metabolism cause Menkes and Wilson diseases in humans and there are direct connections to neurodegenerative diseases (eg, Alzheimer, Parkinson, Creutzfeldt-Jakob, motor neuron diseases). It is crucial to understand how healthy cells control toxic but essential copper so that enlightened intervention is possible when disturbances of copper metabolism become pathological. The chemistry of key molecules will be studied to reveal their essential properties and thereby to understand the molecular basis of the copper-linked diseases.Read moreRead less

The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases. Electron momentum spectroscopy (EMS) has been identified to be an appropriate technique in the study of chemical binding mechanism and orbitals at molecular level. The aims of the project is to study orbitals and interactions of DNA and RNA bases such as adenine, thymine (uracil), guanine and cytosine using momentum space quantum mechanics and EMS experimental techniques. The outcome of the project will improve our understanding of the DNA double helical strand structure.Read moreRead less
