Module overview

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.

Module aims

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

Module content





Indicative content includes:




Photodynamic therapy.  Porphyrin and phthalocyanine complexes, their mode of action.

Metal ions and chelating agents in therapy.  Ligand design, choice of metal ion and targeting strategies.

Radioisotopes for biological imaging and therapy.  Ligand design and targeting strategies.




Target validation: genetic engineering, RNAi.

X-ray crystallography (crystallisation, soaking, X-ray), structure based design. 

Advanced binding interactions: DG, binding role of functional groups and amino acids, the hydrophobic effect.




Enzymes: methods of catalysis, inhibitors.  Examples.




Antibiotics, their discovery.  Natural and semisynthetic β–lactams (penicillins and cephalosporins), their mechanism of action.  Other antibiotics, the problem of drug resistance (MRSA etc).




Receptors: agonists, antagonists, partial agonists, GPCRs, kinase-linked receptors, ligand gated ion-channels, signal transduction, affinity, efficacy, potency.  Examples.




Nucleic acids as drug targets: DNA intercalation, alkylation, chain terminators, nucleic acid therapeutics.  Examples.




Structure-Activity Relationships (SARs), medicinal chemistry strategy and synthesis.




Pharmacokinetics and strategies for improvements:  solubility, permeability, blood-brain barrier, pKa, log P, metabolism, toxic metabolites, excretion.




Formulation

Polymer therapeutics: Polymer-protein and polymer-drug conjugates.  Polymer backbones: linear and branched polymers. Conjugation strategies. Targeting strategies. Cancer therapy with polymers: the Enhanced Permeation and Retention effect (EPR).




Process chemistry, scale-up.




The pharmaceutical industry.  Generic drugs. Ethical aspects. Clinical trials. Patents





 

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)

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate,

 

through coursework, the ability to:

·         research and understand a new aspect of drug discovery, relate it to the process as taught in lectures, show its application with examples and critically evaluate published methods used to incorporate this new aspect into drug design [LOs 3, 5]

 

through written examination, those learning outcomes not covered by the coursework [LOs 1, 2, 4, 5]

 

Thus, the summative assessment for this module consists of:

·         coursework incorporating a critical summary and presentation of the above-mentioned aspect of drug discovery and attendance of all students’ presentations [LOs 3, 5] (20+3 h, deadline week 10, 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 written critical summary coursework consists of annotations on the returned summary and a general comment indicating why the given marks have been assigned and what could be done to improve.  Feedback to the presentation includes general comments explaining the given marks and what could be done to improve.
