METALS IN MEDICINE 5 Lectures
Dr. J. Love
AIM To provide an overview of inorganic medicinal chemistry, with particular emphasis on the role of the metal centre(s) and its mode of action, and current trends in the design of bioactive compounds SYNOPSIS This course will focus on the design, synthesis, and effectiveness of transition metal and organometallic compounds in therapeutic and diagnostic medical applications, and will build on previous inorganic chemistry courses. Particular emphasis will be placed on: • Essential elements, chemotherapeutic and diagnostic elements • Platinum, titanium, and other metal anticancer agents • Gold anti-arthritic drugs • Radiopharmaceuticals and imaging agents, targeted radioactive compounds • Contrast agents for magnetic resonance imaging LEARNING OUTCOMES By the end of this five lecture course, the student should have a good understanding of the history and basic concepts of medicinal inorganic chemistry, and should be able to describe in detail synthetic approaches and mechanisms of action of some important metal-based therapeutic and diagnostic agents.

PHYSICAL ORGANIC ASPECTS OF MEDICINAL CHEMISTRY 5 Lectures
Dr. S. L. Cockroft
AIMS & LEARNING OUTCOMES
This course will explore the role of physical organic chemistry in understanding the relationships between the physicochemical and biological properties of pharmaceutical agents. By the end of the course you will appreciate the importance of structure/activity relationships in modern-day drug design and development. SYNOPSIS 1. Quantifying Drug-Receptor Interactions: ● van der Waals interactions ● electrostatic interactions ● the α/β hydrogen bonding scale ● solvophobic effects ● enthalpy-entropy compensation 2. Solubility & Lipophilicty: ● absolute solubility ● effects of crystal polymorphism on solubility ● partition coefficients as a measure of lipophilicity (logPo/w) ● the pH partition hypothesis ● distribution coefficients (logDo/w) ● membrane partitioning (logDmem) 3. Substituent Effects on Drug Properties: ● lipophilicity (π constants and ClogPo/w) ● pKa ● Hammett substituent constants ● hydrogen bonding ● proximity effects 4. Drug Distribution, Metabolism & Pharmacokinetics (DMPK): ● absorption ● distribution ● metabolism ● excretion ● differences based on administration route 5. Chemoinformatics in Drug Discovery & Design: ● Quantitative Structure Activity Relationships (QSAR) ● database profiling (the origin of Lipinski’s ‘Rule of 5’ for good drug likeness) ● efficient exploration of physical property space in drug screening RECOMMENDED READING ‘Modern Physical Organic Chemistry’ Eric V.

MEDICINAL CHEMISTRY 5 Lectures 5 Lectures
Dr Archer Dr M F Greaney
To build on the basis of the previous course.
To indicate how a knowledge of biological processes can lead to rational drug design.
To explore synthetic routes to the target systems.
SYNOPSIS This course builds on the previous third year course and will emphasise the current approaches to rational design of pharmaceutical products by consideration of drug-receptor interactions. The synthetic routes, and biological implications, of the major therapeutic agents Zantac and Cimetidine (anti-ulcer), Captopril/Enalapril (ACE inhibitors) will be discussed. Inhibition of protein processing by enzymes will be developed as a general concept for future pharmaceuticals. LEARNING OUTCOMES By the end of the ten lecture course, the student should have a good understanding of rational approaches towards the design of important drugs including anti-ulcer drugs and ACE inhibitors, and the biological implications of such therapeutic agents. The student should be aware of the use of enzymes to inhibit protein processing as a concept for the design of future pharmaceuticals. READING Comprehensive Medicinal Chemistry, Volumes 1-6, Ed. C.
