Project Description

Project description

A fully-funded 3 year PhD studentship (Institute for Life Sciences studentship) in chemical biology and medicinal chemistry at the University of Southampton is available. The project will pioneer a novel strategy to tackle antimicrobial resistance through the small molecule approach.

Multidrug resistant (MDR) pathogens are among the top threats to global public health, which have evolved to resist any conventional antibiotics. Many efforts are being made to overcome these problems, and our approach is to utilise a novel drug influx mechanism of bacteria. Based on the fundamental understanding of the signalling system that triggers the expression of a drug influx channel, we aim to develop activators of this signalling pathway. This is a totally new concept of an antibiotic approach in contrast to traditional inhibitory strategies. We will discover and optimise these carbohydrate based small molecule activators of an antibiotic. This accelerated influx of drug molecules will overwhelm the efflux or modification of drugs by bacteria, eventually overturning the resistance. In addition, we will devise a further strategy of delivering this molecule inside infected macrophages, targeting dormant pathogens. Thus, the project will establish resistance breakers and antibiotic potentiators.

You will design, synthesise and test biologically small molecules that activate the drug influx channel. At a certain point, you will also be involved in the development of a drug carrier for macrophage delivery. This interdisciplinary project will be performed in Chemistry in the first place, and as the project is going on, you will need to spend some time in Engineering and Medicine.

The studentship provides fees and stipends on a UKRI scale for three years, and welcomes applicants from UK and EU. We particularly encourage applicants with background of chemistry who are interested in chemical biology, organic chemistry and/or medicinal chemistry.
