Medicinal Chemistry is a scientific discipline at the intersection of chemistry and pharmacy involved with the designing and developing of pharmaceutical drugs. The goal of medicinal chemistry is to discover and create novel chemical entities with therapeutic potential. Research into this field also include examining the structure-activity correlations of already available medications as well as their biological features. In an effort to help new grads understand the potential of drug creation, this book seeks to simplify medicinal chemistry. Recent years have seen significant scientific progress in the area of drug design, which has changed the discipline of medicinal chemistry as a whole. The goal of medicinal chemistry is to locate and create novel therapeutic compounds for the treatment of sickness. This book should be beneficial for courses in medicinal chemistry and pharmacology, since its chapters combine chemical and pharmacological concepts essential for understanding structure-activity connections and molecular mechanisms of drug action. This book is intended to provide knowledge and benefit to the students of degree and post-graduate students of degree and post-graduate students of pharmacy, as well as, personnel engaged in pharmaceutical industries.
