Organic Chemistry of Medicines

Organic chemistry is the study of carbon-containing compounds, which are the building blocks of all living things. Medicinal chemistry is the branch of organic chemistry that deals with the design, synthesis, and testing of drugs. Organic compounds are used in a wide variety of medicines, including antibiotics, pain relievers, and cancer drugs.


Key Points:

  • Organic compounds are used in a wide variety of medicines.
  • Medications like antibiotics, pain relievers, and cancer drugs are created through organic chemistry.
  • Organic chemistry is the study of carbon-containing compounds, which are the building blocks of all living things.
  • Medicinal chemistry is the branch of organic chemistry that deals with the design, synthesis, and testing of drugs.
  • The organic chemistry of medicines is a complex and challenging field, but it is also a rewarding one.

Main Concepts:

The main concepts of the organic chemistry of medicines include:



  • Structure-activity relationships (SARs): SARs are the relationships between the structure of a drug and its biological activity. Medicinal chemists use SARs to design new drugs that are more potent and have fewer side effects.
  • Drug metabolism: Drug metabolism is the process by which the body breaks down and eliminates drugs. Medicinal chemists study drug metabolism to design drugs that are not easily metabolized, so that they can stay in the body longer and have a longer duration of action.
  • Pharmacokinetics: Pharmacokinetics is the study of the absorption, distribution, metabolism, and excretion of drugs. Medicinal chemists study pharmacokinetics to design drugs that are well-absorbed, distributed, and eliminated from the body.

Conclusion:

The organic chemistry of medicines is a complex and challenging field, but it is also a rewarding one. Medicinal chemists play a vital role in the development of new drugs that save lives and improve the quality of life for millions of people around the world.


Experiment: Synthesis of Aspirin

Objective: To synthesize aspirin (acetylsalicylic acid), a common over-the-counter pain reliever and anti-inflammatory drug, from salicylic acid.


Materials:

  • Salicylic acid
  • Acetic anhydride
  • Sulfuric acid (concentrated)
  • Ice
  • Sodium bicarbonate
  • Water
  • Graduated cylinder
  • Beaker
  • Test tube
  • Bunsen burner
  • Thermometer
  • Filter paper
  • Funnel

Procedure:

  1. Weigh 2 grams of salicylic acid and add it to a test tube.
  2. Add 5 milliliters of acetic anhydride to the test tube.
  3. Add 1 drop of concentrated sulfuric acid to the test tube.
  4. Heat the test tube gently over a Bunsen burner while stirring constantly. Monitor the temperature using a thermometer and do not allow it to exceed 70°C.
  5. Continue heating for about 10 minutes, or until the reaction mixture becomes clear.
  6. Allow the reaction mixture to cool to room temperature.
  7. Add 10 milliliters of ice water to the test tube and stir.
  8. Filter the mixture using a funnel and filter paper.
  9. Wash the crystals with cold water and then dry them between two filter papers.
  10. Dissolve the crystals in a small amount of hot water.
  11. Add a few drops of sodium bicarbonate solution to the hot solution until effervescence ceases.
  12. Allow the solution to cool and then filter it again.
  13. Dry the crystals between two filter papers.

Significance:

  • This experiment demonstrates the organic chemistry of medicines, specifically the synthesis of aspirin from salicylic acid.
  • It highlights key procedures in organic chemistry, such as heating, filtration, and purification.
  • The experiment allows students to understand the chemical structure of aspirin and its medicinal properties.
