Study Notes
Natural Sources
-
Plants: Many drugs are derived from plants, such as:
- Morphine from opium poppy (Papaver somniferum)
- Digoxin from foxglove (Digitalis purpurea)
- Vinblastine from Madagascar periwinkle (Catharanthus roseus)
-
Animals: Some drugs come from animals, including:
- Heparin from pig intestines
- Insulin from pig or cow pancreas (although most is now produced recombinantly)
-
Microorganisms: Microbes are a source of various drugs, such as:
- Antibiotics like penicillin from Penicillium mold
- Tetracycline from Streptomyces bacteria
Synthetic Sources
-
Chemical Synthesis: Many drugs are created entirely in a laboratory through chemical reactions, such as:
- Aspirin
- Ibuprofen
- Antidepressants like fluoxetine (Prozac)
-
Semi-Synthetic Sources: Some drugs are derived from natural sources but undergo significant chemical modification, including:
- Semi-synthetic opioids like hydrocodone and oxycodone from opium
- Semi-synthetic antibiotics like ampicillin from penicillin
Recombinant Sources
-
Genetic Engineering: Recombinant DNA technology allows for the production of drugs through genetically modified organisms, such as:
- Insulin from bacteria
- Human growth hormone from bacteria
- Vaccines like HPV and Hepatitis B from yeast or bacteria
Other Sources
-
Marine Sources: Some drugs are derived from marine organisms, including:
- Anti-cancer drugs like trabectedin from sea squirts
- Pain relievers like ziconotide from cone snails
-
Fermentation: Fermentation processes can be used to produce drugs, such as:
- Antibiotics like erythromycin from bacteria
- Statins for cholesterol reduction from fungi
Natural Sources
- Plants are a source of many drugs, including morphine from opium poppy, digoxin from foxglove, and vinblastine from Madagascar periwinkle.
- Animals provide some drugs, such as heparin from pig intestines and insulin from pig or cow pancreas (although most insulin is now produced recombinantly).
- Microorganisms like Penicillium mold and Streptomyces bacteria are used to produce antibiotics like penicillin and tetracycline.
Synthetic Sources
- Chemical synthesis in a laboratory is used to create drugs like aspirin, ibuprofen, and fluoxetine (Prozac).
- Semi-synthetic sources involve deriving drugs from natural sources but with significant chemical modification, resulting in drugs like hydrocodone and oxycodone from opium, and ampicillin from penicillin.
