Professor Eric Oldfield was educated in London, Bristol and Sheffield, then moved to the US as a European Molecular Biology Organization Fellow at Indiana University with Adam Allerhand and a Visiting Scientist at MIT with John Waugh.
In recent work, carried out in collaboration with the groups of J. Urbina, R. Docampo and S. Croft, we have branched out into yet another new area, molecular parasitology. We first found evidence for extremely large levels of inorganic di- and triphosphate in the protozoa which cause African sleeping sickness and malaria. This then led us to the idea that it might be possible to kill these and other related parasites by using stable diphosphate analog drugs to block specific metabolic pathways, and this indeed was found to be the case. The drugs used, called bisphosphonates, have been used to treat bone-resorption diseases for over 20 years, but their mode of action had been unknown. However, in recent work, we have shown that the most potent, nitrogen-containing bisphosphonates used in treating bone diseases are also potent drugs in killing parasites, and act to perturb protein prenylation and signaling by inhibiting the enzyme farnesyl pyrophosphate synthase. Using quantum chemistry and molecular modeling, we showed that the charged ammonium side-chains in the drugs act as carbocation transition state analogs, and bind into the active site of the enzyme, blocking its action. This gives a sound molecular basis for drug design, based on known protein structures and mechanisms of drug action, and is a topic of considerable current interest.
And finally, in our most recent work we have found that it is possible to apply the computational methods used in modern drug design and drug discovery to the immune system where we are employing QSAR (quantitative structure activity relationships) to probe innate immunity. In particular, we are interested in the development of drugs which activate γδ T cells, opening the way to new therapies for infectious diseases, cancer, and vaccine development.
