Competition Funded PhD Project (European/UK Students Only)
The project aims to integrate novel enzymes (biocatalysts) with synthetic catalysts (chemocatalysts) to develop new methods for more efficient, lower cost and environmentally sustainable production of pharmaceuticals which are urgently required to combat disease. Currently most pharmaceuticals are produced by multi-step synthetic methods, with deleterious reagents and solvents, from non renewable petrochemicals, all of which come at significant cost. In this project we aim to develop more sustainable processes, combining biocatalysts and chemocatalysts, to deliver key pharmaceutically relevant compounds under mild conditions, in water, utilising more benign reagents and renewable feedstocks. Many biocatalysts and chemocatalysts are incompatible. A key challenge in this project is the development of technology that will enable multiple different enzymes and chemocatalysts to be combined in one reaction vessel. The combination of multiple catalytic transformations in a single reaction cascade represents a potential step-change improvement in efficiency, avoiding multiple work-up and purifications steps required to isolate intermediates. To address this major challenge, we recently developed the first example of integrated chemobiocatalytic cascades, including enzymes with transition-metal catalysed (TM) cross-coupling chemistry, in one reaction vessel, to achieve regiodivergent arylation or alkenylation of aromatic scaffolds . In collaboration with AztraZeneca, we aim to develop new chemoenzymatic cascade reactions which will enable functionalization of pharmaceutical scaffolds to generate compounds with improved biological activity and physical properties for further development. Training will be provided in biological chemistry/biocatalysis and in chemocatalysis under the supervision of Prof. Jason Micklefield and Prof. Michael Greaney. The project will also involve close interactions with AztraZeneca scientists and will include a placement period at AztraZeneca where the student can obtain additional training and skills in world leading industrial labs. Students from Chemistry or Biological Sciences degree programmes, who possess a desire to do cutting edge research at the Chemistry-Biology interface are encouraged to apply.
Applications are invited from UK/EU nationals only. Applicants must have obtained, or be about to obtain, at least an upper second class honours degree (or equivalent) in a relevant subject.
