SULSA PhD Studentship in Structure-based Drug Design / Molecular
Modeling / X-ray crystallography: Structure-based design of 6PGDH
inhibitors, a target for African sleeping sickness
A fully-funded PhD project in the University of Dundee / School of Life
Sciences in the group of Dr. Ruth Brenk is now available. The project is
a funded by SULSA and a collaboration with Ian Gilbert (University of
Dundee) and Mike Barett (University of Glasgow).
Human African trypanosomiasis is a disease with an urgent need for the
development of better drugs. A promising target is 6-phosphogluconate
dehydrogenase (6PGDH) which has been validated genetically and
chemically. Potent substrate-like inhibitors have been synthesised but
they suffer from a lack of in vitro antiparasitic activity This is
probably due to the high polarity of these compounds. Consequently,
various phosphate prodrugs have been investigated and two trypanocidal
compounds where identified. Despite these promising results stability
issues remain. An alternative approach is to develop compounds with
better intrinsic drug-like properties. The available crystallographic
data enables a structure-based design approach to achieve this goal. An
initial virtual screening has been carried out and a variety of
inhibitors has been identified. The project aims to characterize these
hits in terms of determination of inhibition constants for parasitic and
human 6PGDH and determination of binding modes by use of X-ray
crystallography. Based on these results more potent analogues will be
designed.
This project will expose the student to a wide range of methods (protein
purification, crystallisation, crystal structure analysis, enzyme
kinetics, structure-based design, synthesis planning) and would fit a
student with a background in the area of life sciences and a strong
interest in protein-ligand interactions.
The 5* research rated School comprises 70 Research Groups and 700 staff
from 51 countries. Dundee, set on the east coast of Scotland, lies in an
area of outstanding natural beauty, including large sandy beaches and
challenging hills. Rainfall charts show this is one of the most sunny &
dry places in the UK.
