Cinchona alkaloids

Cinchona alkaloids are natural compounds extracted from the bark of the cinchona tree, historically significant for their use in treating malaria. The most well-known of these is quinine, which helps combat the malaria parasite by interfering with its ability to survive in human red blood cells. Other alkaloids in this group include quinidine, used as an antiarrhythmic drug, and cinchonine, which has some medicinal properties. These molecules possess specific chemical structures that allow them to target certain parts of the parasite or human body, making them vital in the development of antimalarial and other medications.
