Example: Aspirin, a common over-the-counter medication, is derived from salicylic acid found in the bark of willow trees. It is a biologically active compound widely used to reduce pain, inflammation, and fever.
Many biologically active compounds are at the heart of traditional medicine practices, underpinning remedies that have been used for centuries.
Let's delve further into alkaloids, a significant group of biologically active compounds. Alkaloids are naturally occurring compounds primarily found in plants. They contain nitrogen atoms and have diverse roles in plants, including acting as defense mechanisms against herbivores. In humans, alkaloids can have profound effects on physiology. For instance, caffeine, an alkaloid found in coffee and tea, is a stimulant that affects the central nervous system by blocking the inhibitory neurotransmitter adenosine, resulting in increased alertness. Other noteworthy alkaloids include quinine, used to treat malaria, and atropine, used in medicine for its muscle-relaxing properties. The diversity and impact of alkaloids illustrate the vast potential of biologically active compounds in science and medicine.
Importance of Biologically Active Compounds in Medicine
