“Practical Medicinal Chemistry–I” is a well-structured and student-oriented laboratory manual designed to provide a clear understanding of fundamental experimental techniques in medicinal chemistry. The book focuses on developing practical skills through systematic and easy-to-follow procedures, enabling learners to connect theoretical concepts with laboratory applications.
The manual includes the synthesis of important medicinal compounds and intermediates such as benzimidazole, benzocaine, phenytoin, barbiturates, and phenothiazine, helping students understand reaction mechanisms and synthetic approaches. It also covers the assay of commonly used drugs, emphasizing accuracy, analytical methods, and standard pharmaceutical practices.
In addition, the book introduces the determination of partition coefficients of drugs, providing insight into physicochemical properties that influence drug absorption and distribution. The inclusion of computational tools and ChemDraw basics further enhances learning by familiarizing students with modern techniques used in medicinal chemistry.
With its clear presentation and focus on hands-on learning, this book serves as a valuable resource for building laboratory competence, analytical skills, and a strong foundation in practical medicinal chemistry.
