Medicinal Chemistry I: Foundations of Drug Action and SAR

Understanding how chemical structures dictate biological activity is the cornerstone of modern pharmacy and drug development. This text-based course guides you through the core concepts of medicinal chemistry, helping you decode the relationship between molecular structure and therapeutic action. You will start with foundational definitions, chemical bonding, and the physicochemical properties that influence how drugs behave in the human body. From there, you will explore structure-activity relationships (SAR) across major drug classes, drug metabolism pathways, and the chemical mechanisms behind therapeutic agents. What you'll learn: - Understand the fundamental physicochemical properties that govern drug absorption, distribution, and action. - Analyze Structure-Activity Relationships (SAR) to see how molecular modifications alter drug potency and selectivity. - Study drug metabolism, including Phase I and Phase II biotransformations and their clinical significance. - Explore the chemical classification and mechanisms of action of key therapeutic agents, including those acting on the nervous system. - Practice evaluating medicinal chemistry concepts through targeted multiple-choice review questions. - Discover modern drug design principles, including an introduction to computer-aided drug design (CADD) concepts. The course begins with essential terminology and basic chemical principles before moving into detailed structural classifications and metabolic pathways. You will consolidate your understanding through written exercises and structured conceptual reviews. This course is designed for pharmacy students, chemistry undergraduates, and anyone seeking a clear, structured introduction to the molecular basis of medicine. A basic background in organic chemistry is helpful but not required. Begin exploring the molecular world of drug design today.
