Aims
To provide an overview of the methods and approaches used in modern chemical biology and drug discovery.
To introduce key concepts and techniques in chemical biology, including Synthesis of DNA, RNA and peptides
To introduce key concepts and techniques in drug discovery. To discuss the methods used in key stages of a project i.e. target identification and validation, hit discovery, hit validation, hit-to-lead optimisation and lead optimisation.
Outline Of Syllabus
Chemical Biology and Drug Discovery
The discovery of new drugs to treat unmet needs of patients is a global undertaking. This module
covers modern topics in drug discovery e.g., target validation, hit identification and the pre-clinical optimisation of drugs. Theoretical concepts and experimental methods will be discussed in detail. The underpinning chemical biology methods will be described in detail, focusing on how chemical biology interlinks with drug discovery. Recent literature is used to illustrated with case studies from recent discovery projects.
Methods in Drug Discovery
Dr IR Hardcastle
List of topics covered:

Formative Assessments
Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.
| Description | Semester | When Set | Comment |
|---|---|---|---|
| Written exercise | 1 | M | Formative written exercise (Max 100 words) |
Assessment Rationale And Relationship
The summative coursework exercise will assess the students’ ability to understand and apply their learning to relevant literature case studies in drug discovery and chemical biology.
The summative online exam will test key concepts, definitions and examples across the taught material.
The formative coursework exercise will assess and provide feedback on the students’ ability to communicate their understanding and applied learning with a relevant literature case study in drug discovery.
