ADVANCED MEDICINAL CHEMISTRY - 2021/2
Module code: CHEM032
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
The module brings undergraduates to a position of knowledge which would facilitate strong understanding and skills in a new role in drug discovery research. It covers knowledge and skills required for all aspects of the modern drug discovery process and also teaches developments in inorganic medicinal chemistry, antibiotics and polymer therapeutics.

|Assessment type||Unit of assessment||Weighting|
|Examination||EXAMINATION: 2 hours||70|
The assessment strategy is designed to provide students with the opportunity to demonstrate,
through coursework, the ability to:
research and understand a drug discovery target, propose and rationalise analogues of a given molecule which should show improved medicinal chemistry properties, and propose syntheses of those analogues with reference to the literature [LOs 2, 3, 4]
through written examination, all learning outcomes, including those not covered by the coursework [LOs 1, 2, 3, 4, 5]
Thus, the summative assessment for this module consists of:
· coursework incorporating oral and written presentation of a research proposal for a medicinal chemistry programme, and attendance at all students’ presentations [LOs 2, 3, 4] (20+3 h, 30%)
· examination [LOs 1, 2, 4, 5] (2 h, 70%)
Formative assessment and feedback
Small problem-solving tasks are included in some lectures. During the task, the lecturer moves amongst the groups commenting and guiding the students’ starting points and answering strategies. Common difficulties are highlighted to the whole class and the final solution is given on the board/visualiser.
Feedback to the presentation includes general comments explaining the given marks and what could be done to improve. Feedback to written coursework consists of annotations on the returned proposal and a general comment indicating why the given marks have been assigned and what could be done to improve.
- To give students an advanced understanding of how drugs work and are designed, discovered and developed.
- To provide students with the ability to critically evaluate published medicinal chemistry programmes and make suggestions for drug design

Overall student workload
Workshop Hours: 3
Independent Study Hours: 116
Lecture Hours: 30
Tutorial Hours: 1
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Build on students’ knowledge of the basic drug discovery process and characteristics of drugs by providing them with a fuller understanding of considerations during their design. This is bolstered by many examples and case studies of small molecule drugs, inorganic agents, antibiotics and polymer therapeutics.
- Provide students with medicinal chemistry tools which can be applied to new drug discovery programmes and permit critical evaluation of published programmes.
The learning and teaching methods include:
- Formal lectures which contain occasional group problem-solving tasks. (32 h)
- Coursework: a written critical summary of an aspect of medicinal chemistry not discussed in lectures as well as a short oral presentation on the topic to the class followed by questions. (20 h)
- All students attend all coursework presentations so gain brief insights into these additional aspects of medicinal chemistry. (3 h)
- Independent learning (reading (some directed) and revision). (92 h)
- Revision tutorial (1 h)
- Written exam (closed book, 2 h)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
