Medicinal Chemistry of Drugs
Overview
Medicinal chemistry is the application of chemistry to the design, synthesis, and testing of drugs. It involves the study of the chemical structure, properties, and biological activities of drugs, as well as the development of new and improved drugs.
Key Points
Medicinal chemistry is a multidisciplinary field that draws on principles from chemistry, biology, pharmacology, and other disciplines. The main goal of medicinal chemistry is to develop drugs that are safe, effective, and affordable.
Medicinal chemists use a variety of techniques to design and synthesize drugs, including computer-aided design, combinatorial chemistry, and high-throughput screening. The development of a new drug is a long and complex process that can take many years and millions of dollars.
* Medicinal chemistry has played a major role in the development of many of the drugs that we use today, including antibiotics, painkillers, and cancer drugs.
Main Concepts
Drug design: The process of designing new drugs based on the knowledge of the disease and the biological target. Drug synthesis: The process of synthesizing drugs in the laboratory.
Drug testing: The process of testing drugs in animals and humans to evaluate their safety and efficacy. Pharmacokinetics: The study of how drugs are absorbed, distributed, metabolized, and excreted in the body.
* Pharmacodynamics: The study of the effects of drugs on the body.
Experiment: Synthesis of Aspirin
Objective:

To synthesize aspirin, a non-steroidal anti-inflammatory drug (NSAID) commonly used as an analgesic, antipyretic, and anti-inflammatory agent.


Materials:

  • Salicylic acid
  • Acetic anhydride
  • Sulfuric acid
  • Ice bath
  • Distilled water
  • Aspirin filtration apparatus

Procedure:

  1. Dissolve 1 g of salicylic acid in 5 mL of acetic anhydride in a round-bottomed flask.
  2. Add 3 drops of concentrated sulfuric acid to the flask and swirl gently.
  3. Cool the flask in an ice bath for 15 minutes.
  4. Filter the reaction mixture through an aspirin filtration apparatus.
  5. Wash the crystals with cold distilled water.
  6. Recrystallize the aspirin from a mixture of hot water and ethanol.

Key Procedures:

  • Esterification: The reaction between salicylic acid and acetic anhydride forms aspirin through an esterification reaction.
  • Filtration: The aspirin crystals are separated from the reaction mixture by vacuum filtration.
  • Recrystallization: The aspirin crystals are purified by recrystallization, which removes impurities and improves the crystal structure.

Significance:

This experiment allows students to synthesize and characterize aspirin, a widely used cardiovascular drug. It provides insights into the importance of organic synthesis and the chemical reactions involved in drug development. By understanding the medicinal chemistry of aspirin, students can appreciate its pharmacological effects and potential therapeutic applications.
