Medicinal chemistry involves the application of a number of specialized disciplinary approaches all focused on the ultimate goal of drug discovery. Drug target identification and validation, rational (target-based) drug design, structural biology, computational-based drug design, methods development (chemical, biochemical, and computational), and “Hit-to-lead” development are all aspects of medicinal chemistry. The techniques and approaches of chemical biology, synthetic organic chemistry, combinatorial (bio)chemistry, mechanistic enzymology, computational chemistry, chemical genomics, and high-throughput screening are all used applied by medicinal chemists towards drug discovery.

For our Pharm.D. students, medicinal chemistry is integrated with pharmacology to present a coherent picture of the principles of drug action. Pharmacology mainly deals with drug action at the cellular, tissue/organ and organism levels. Medicinal chemistry focuses on the molecular aspects of drug action: interactions with the drug targets from both the drug and the target point of view, the relationship of drug chemical structure to drug action and the effects of metabolism on the drug structure and hence its action.
