ADVANCED MEDICINAL CHEMISTRY - 2020/1
Module code: CHEM037
The module brings students to a position of knowledge, understanding and skills which would facilitate a new role in drug discovery research. It covers the most important aspects of modern medicinal chemistry in detail and also teaches developments in radioisotope medicinal chemistry, antibiotics and nanotherapeutics.

The assessment strategy is designed to provide students with the opportunity to demonstrate
- through coursework, the ability to research and understand a specified target protein, evaluate an imaginary hit molecule (with reference to published target ligands) in terms of possible binding interactions, and propose analogues with improved efficacy along with literature-based routes to their synthesis
- through written examination, all learning outcomes
Thus, the summative assessment for this module consists of:
- coursework incorporating a written research proposal and oral presentation to the class including the answering of questions
- examination (2 h)
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.
The research proposal oral presentation takes place one week before the deadline for the written proposal to allow the students to act on (and therefore better internalise) immediate feedback. For the presentation, some feedback is given immediately in the form of questions and suggestions for improvement of the proposed research. Formal written feedback is given later including marks, why they were awarded and what could be done to improve. Feedback to the written research proposal consists of annotations on the returned document and general comments on the mark sheet indicating why the given marks have been assigned and what could be done to improve.
- • give students an advanced understanding of how drugs work and are designed/discovered and developed.
- • provide students with the ability to critically evaluate published medicinal chemistry programmes and make suggestions for drug design.

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 drug design.
- provide students with medicinal chemistry ‘tools’ which can be applied to the design of new medicinal chemistry programmes and permit critical evaluation of published programmes.
The learning and teaching methods include:
- formal lectures bolstered by many examples and case studies of small molecule drugs, inorganic agents, antibiotics and nanotherapeutics as well as occasional group problem-solving tasks.
- coursework: a written and orally presented research proposal for a medicinal chemistry programme based on a given target and imaginary hit.
- all students attend all oral presentations to gain insights into these additional aspects of medicinal chemistry as well as practise their critical evaluation through asking questions.
- independent learning (reading and revision).
- revision tutorial
- written exam
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.
