Medicinal Chemistry usually involved the molecular structure, synthesis methods, properties, mechanism of action, biological activity, and drug design of drugs. Specifically, the course would introduce the composition and structure of drug molecules, including the chemical formula, bond length, functional groups, and other characteristics of the drug. Then, he would explain the synthesis methods of drug molecules, including organic synthesis, physical and chemical synthesis, and so on. Next, it would introduce the properties of the drug, including its melting point, boiling point, dissolution, stability, and so on. After that, he would explain the mechanism of action of the drug, including how the drug interacted with the organism, how the drug worked, and the adverse effects of the drug. Finally, he would explain drug design, including drug screening, drug synthesis, and drug structure-activity relationship research. In addition, Medicinal Chemistry also covered the safety and adverse reactions of drugs, including the effects of drugs on the human body, drug interactions, and drug toxicity. At the same time, it will introduce the drug's commerce and clinical application, including the preparation, production, sales, and use of the drug.
