Medicinal Chemistry is a multidisciplinary field that merges organic chemistry, pharmacology, biochemistry, and computational sciences to design and develop therapeutic agents. It plays a central role in the drug discovery pipeline, beginning with the identification and validation of biological targets such as enzymes or receptors and progressing through hit identification, lead optimization, and preclinical development. The process focuses on understanding the structure–activity relationship (SAR) of molecules and modifying their structures to enhance potency, selectivity, pharmacokinetics, and safety. Medicinal chemistry is not limited to small molecules but also encompasses peptides, nucleic acid-based drugs, and biologics. Advanced methods such as combinatorial chemistry, natural product chemistry, and in silico drug design with artificial intelligence and machine learning are transforming the field by accelerating lead discovery and optimization. Its applications are broad, addressing therapeutic areas including oncology, cardiovascular diseases, neurological disorders, and infectious diseases. The growing demand for targeted and personalized medicine, combined with rising collaboration between pharmaceutical companies, biotech firms, and CROs, continues to fuel the importance of medicinal chemistry in creating innovative, safe, and effective drug candidates.
