Project Description

Applications are invited from Graduates in Chemistry, Pharmacy and Medicinal Chemistry programs to join our group. The project encompasses the synthesis and biological screening of a novel group of cytochrome P450 inhibitor probes and there development towards diagnostic and therapeutic tools.

Cytochrome P450s (CYP450s) constitute a large family of haem-centred, with fundamental roles in the biotransformation of endogenous (steroid hormones, fatty acids, prostaglandins) and exogenous molecules (drugs, environmental chemicals, agrochemicals). As a direct result of their importance, particularly in xenobiotic and drug metabolism, a great deal of research has been conducted into the roles, identification of their sequences and their catalytic mechanism. Whilst a number of CYP450s, particularly human liver CYP450s and extra-hepatic CYP450s (i.e. CYP1A1, CYP1B1 and CYP2W1) have been the subject of intense investigation, much is still to be learnt from these mixed-function oxidases. This reflects the difficulties associated with studying these enzymes as (i) they are encoded by large gene families and their functions cannot be predicted from their gene sequence, (ii) they are difficult to assay, isolate and purify, so classical biochemical methods are often ineffectual in identifying enzymes of interest, (iii) these proteins are membrane bound and often dependent on co-enzymes and co-factors, making them difficult to express as a functional enzymes in cellular systems, and (iv) polymorphisms and epigenetic regulation alter their expression and functional activity. As a result, new approaches to identifying, evaluating and quantifying functionally active CYP450s are of the upmost importance.

As a result, this project will involve the following a.) expand a library of diverse structural cytochrome P450 inhibitors; b.) iterative biological testing of the compound library to new CYP450 enzymes to expand the scope of the probe library. You will undertake the synthesis and in-house testing of these compounds in our world leading facilities, where you will have access to state of the art laboratories and analytical equipment.

Eligibility Criteria:

You must have, or expect to achieve, at least a 2:1 honours degree or international equivalent. A strong background in chemical synthesis, with a knowledge of microbiological techniques and protein purification being advantageous.

This award is available to UK/EU and international applicants. If English is not your first language, you must have IELTS 7 with at least 6.5 in the written component, or equivalent.

How to apply:

Please apply through the University’s Postgraduate Application portal (http://www.ncl.ac.uk/postgraduate/apply/). Only mandatory fields need to be completed however, you will need to include the following information:

•insert the programme code 8300F in the programme of study section
•select ‘PhD in the Faculty of Medical Sciences – Pharmacy’ as the programme of study
•attach a covering letter and CV. The covering letter must state the title of the studentship, quote the reference code PH004 and state how your interests and experience relate to the project.
