Medicinal Chemistry is an interdisciplinary subject incorporating basic principles of organic chemistry, biology, biochemistry, toxicology, pharmacology and molecular biology to understand how biologically active compounds (pharmaceuticals) operate in living systems. Selected topics in medicinal and pharmaceutical chemistry including the design and synthesis of new drugs as well as their pharmacodynamic and pharmacokinetic properties will be covered. We will also examine the path of pharmaceuticals from inception to clinical use by studying specific classes of drugs.
