Aims

To provide an overview of the methods and approaches used in modern drug discovery. To introduce the key stages of a project i.e. target identification and validation, hit discovery, hit validation, hit-to-lead optimisation and lead optimisation. To familiarise students with the most commonly used synthetic methods in medicinal chemistry. To provide students with an understanding of the role of medical imaging in drug discovery, synthetic methods for the incorporation of radioisotopes into biologically active molecules and the quality control requirements for clinical production.

Outline Of Syllabus

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, along with the preparation and application of radiopharmaceuticals for imaging and therapy. It is illustrated with case studies from recent discovery projects.

Teaching Rationale And Relationship

Key concepts and supporting examples are delivered by online teaching materials. Seminars are used to reinforce key concepts, provide additional examples and to provide practice questions. Online quizzes revise and reinforce conceptual understanding.
Written assignments allow students to access and review representative primary literature adding depth to conceptual understanding.


Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss this.

Assessment Methods

The format of resits will be determined by the Board of Examiners
