Cinchona officinalis
L'arbre sud-américain dont l'écorce a révolutionné la médecine — source de quinine pour traiter le paludisme.
Cinchona officinalis, a South American tree, is the historical source of quinine and quinidine, alkaloids with antimalarial and antiarrhythmic properties. Its bark is used traditionally for malaria, fever, and leg cramps, and as a digestive bitter. Key active compounds include quinine, quinidine, cinchonine, and cinchonidine, which act on multiple physiological targets.
Quinine and quinidine are the primary active alkaloids. Quinine exerts antimalarial effects by inhibiting heme polymerase in Plasmodium parasites, leading to toxic heme accumulation. Quinidine is a class Ia antiarrhythmic that blocks sodium channels and prolongs the cardiac action potential. Both compounds also have mild skeletal muscle relaxant properties via inhibition of nicotinic acetylcholine receptors at the neuromuscular junction. Cinchonine and cinchonidine contribute to the bitter taste and digestive stimulation through activation of bitter taste receptors (TAS2Rs) on the tongue and gut.
