Designing, synthesizing, and advancing pharmaceutical agents for commercial distribution is primarily the subject of study under medicinal chemistry. It draws from diverse scientific disciplines like pharmacology, synthetic organic chemistry, and other biological domains. Medicinal compounds, utilized as pharmaceuticals, fall into two primary categories, namely, small organic molecules and biologics. Furthermore, this discipline scrutinizes the efficacy of inorganic and organometallic compounds utilized as medicinal substances. Crucially, medicinal chemistry assumes a pivotal role in scrutinizing the chemical facets of identifying and synthetically modifying novel chemical entities to render them apt for therapeutic utility. This book provides significant information of the discipline of medicinal chemistry to help develop a good understanding of the subject. It elucidates the concepts and innovative models around prospective developments with respect to medicinal chemistry. Those in search of information to further their knowledge will be greatly assisted by this textbook.
