Molecules in medicine

This module surveys a prominent area of contemporary medical science: the molecular understanding of disease and its use in the design of drugs to treat different disease states and conditions. You’ll be introduced to a range of drug therapy topics, including heart disease, infectious diseases (including bacterial and viral), cancer, and neuropharmacology. You will also have the opportunity to undertake independent research, culminating in the production of a literature review which is excellent preparation for the MSc project module (S810). 


S807 is an optional module in our:

It can also count towards E68, F60 and F62, which are no longer available to new students.

Module code


  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.
Study level
Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU postgraduate modules correspond to these frameworks.

What you will study

This subject is of fundamental importance in medical therapy, because it enables potential drug intervention strategies to be identified and the drugs to be designed. Such drugs, designed to help the body to cope with transient or chronic disease, can both enhance quality of life and increase longevity.

The module is designed to enable you to develop a broad and balanced appreciation of these areas of contemporary medicine, rather than a detailed ‘professional’ knowledge. You will study two introductory topics which give a broad overview of the key scientific concepts and then study four topics (heart disease, infectious diseases - both bacterial and viral, cancer and neuropharmacology) in more detail.

You will learn

The aims of the module are to:

  • introduce higher-level study of the molecular aspects of drug action, particularly in areas at the forefront of research
  • develop the skills appropriate to study at masters level, so that you can both articulate your understanding of the molecular basis of drug action and apply the same skills to other areas of study
  • develop communication skills using poster presentations and online forums
  • develop the use of IT skills in the interpretation and dissemination of scientific information.

By the end of the module you should be able to:

  • demonstrate an understanding of the molecular principles that underlie the design, development and delivery of drugs
  • describe, with suitable examples, the thinking behind molecular intervention in the treatment of disease
  • explain the medical benefits and assess the risks of using drug therapies described in the module
  • use electronic means of communication and search and retrieve information electronically
  • assess secondary and some primary literature in a given area of medicinal chemistry
  • prepare an extended, cogently argued piece of writing that summarises an aspect of medicinal chemistry
  • manipulate simple mathematical expressions that describe the measurement of drug activity
  • use scientific software to analyse and present data.
Normally you must have completed either this module SH804, SD815, SEH806, S808, S809, S819, or S827 before progressing to the MSc project module (S810) or the MSc project module for MSc in Professional Science (SXB810). Before progressing to the MSc project module for MSc in Medicinal Chemistry (SXM810) normally you must have completed either this module, or S827. 

Teaching and assessment

Support from your tutor

You will have a tutor who will help you with the study material and mark and comment on your written work, and whom you can ask for advice and guidance. Electronic communication will be used extensively. All study activities will be completed online.

Contact us if you want to know more about study with The Open University before you register.


The assessment details can be found in the facts box above.

You will be expected to submit your tutor-marked assignments (TMAs) online through the eTMA system unless there are some difficulties which prevent you from doing so. In these circumstances, you must negotiate with your tutor to get their agreement to submit your assignment on paper.

There are two interactive computer-marked assignments (iCMAs) which cover the general medicinal chemistry and drug design themes and four tutor-marked assignments (TMAs) which cover the specific disease therapies. One of the TMAs also includes a poster presentation (to be presented online).

As a student of The Open University, you should be aware of the content of the academic regulations which are available on our Student Policies and Regulations website.

    Entry requirements

    To register for any of the science masters courses you must normally hold a UK honours degree (or equivalent qualification) in science or a science-related subject. An undergraduate degree in the areas of chemistry, physics, biology and medicine would be preferred. As this module deals with medicinal chemistry, knowledge of chemistry, and especially organic chemistry, would be particularly helpful. If you have other study or experience that you believe equips you to study at postgraduate level you can still apply, but must supply evidence of that study or experience. Your case will be referred to our MSc in Science Admissions Panel. For further advice, contact the postgraduate science team.

    We strongly recommend that you check whether or not your background and experience are sufficient to give you a sound basis on which to tackle this module, since we have found that students who are appropriately prepared have the best chance of completing their studies successfully.

    You will also need good computing skills (e.g. able to search the Web, use email and use word processing packages).

    All teaching is in English and your proficiency in the English language should be adequate for the level of study you wish to take. We strongly recommend that you have achieved an International English Language Testing System (IELTS) score of at least 7. To assess your English language skills in relation to your proposed studies you can visit the IELTS website.

    If you have any doubt about the suitability of the module, please contact us.
