Synthesis of Biologically Active Indolizidine and Pyrrolizidine Natural Products

This research will be in the area of synthetic organic chemistry and will focus specifically on the synthesis of heterocyclic natural products. The targets of this project are the indolizidine and pyrrolizidine alkaloids. These systems are of interest in the possible treatment of various diseases such as cancer, diabetes and viral infections such as AIDS, and some of them have the potential to function as potent analgesics or as potential treatments for Alzheimer’s disease and other neurological disorders. Examples of such compounds include the well known "poison frog alkaloids".

The Synthesis of the Pyrrolobenzodiazepine Antitumour Antibiotic Natural Products

This research is in the broad areas of synthetic organic chemistry, natural products chemistry and heterocyclic chemistry. The pyrrolobenzodiazepines are a class of naturally occurring alkaloids that have high potency as both antitumour compounds for use in cancer research and as antibiotics with known activity against "superbugs". The target of this project is to synthesise analogues of these systems for screening as antibiotics and against cancer cell lines.

The Synthesis of New Potential Antibiotics

It's well known that "superbugs" with resistance to existing antibiotic drugs are of huge concern to society. The need for potential new antibiotics is therefore high. In this project, which is in the area of synthetic organic chemistry, the target is the synthesis of a series of molecules related to the existing penicillin systems, but with sufficient differences built in to prevent resistance.

Azides as Tools for Synthetic Chemistry and Chemical Biology

This project builds upon our existing published research in this area. Azides are reactive systems that can be used to construct a wide variety of heterocyclic molecules and this project therefore falls in the area of synthetic organic chemistry. The target molecules of this project include completely new heterocycles, but also systems such as mitomycin C, a clinically prescribed antitumour agent. The project is also concerned with the design and synthesis of azides for incorporation into biological systems where they can be used as probes or tags by molecular biologists.

The Synthesis of Heterocycles of Pharmaceutical and Biological Importance

Many molecules used in medicine today are heterocycles. We have a number of projects available in the area of synthetic organic chemistry which focus upon the synthesis of such molecules. These include penicillin type systems, natural products, alkaloids, benzodiazepines and oxadiazoles. The diseases that these molecules target are many, but the list includes anticancer compounds, new antibiotics, new anti-HIV/AIDS drugs and systems targeted at Alzheimer's disease.
