Medicinal Chemistry

Medicinal chemistry is a interdisciplinary field that combines principles of chemistry, pharmacology, and biology to design, develop, and evaluate compounds with therapeutic properties. It involves the structure-activity relationship (SAR) studies of potential drugs, optimizing their effectiveness and safety for treating various diseases. Medicinal chemists work to understand how these compounds interact with biological systems, aiming to improve their pharmacokinetic and pharmacodynamic profiles. This field is central to pharmaceutical development, encompassing drug discovery processes, synthesis of new molecules, and investigations into the mechanisms of action of drugs.
