Quinine is a medication used to treat malaria and babesiosis. [5] This includes the treatment of malaria due to Plasmodium falciparum that is resistant to chloroquine ...
The quinine in tonic water will fluoresce under ultraviolet light. In fact, quinine will visibly fluoresce in direct sunlight against a dark background. [19] The quinine molecules release energy as light instead of heat, which is more common. The state is not stable, and the molecules will eventually return to a ground state and no longer glow ...
Cinchonism is a pathological condition caused by an overdose of quinine or its natural source, cinchona bark. Quinine and its derivatives are used medically to treat malaria and lupus erythematosus. In much smaller amounts, quinine is an ingredient of tonic drinks, acting as a bittering agent. Cinchonism can occur from therapeutic doses of ...
Quinquina is an aromatised wine, a variety of apéritif.Traditionally quinquinas contain cinchona, which provides quinine, introduced to Europe from Peru in the 17th century by Spanish missionaries, [citation needed] and used both in treating malaria [1] and as the principal ingredient in tonic water.
The most probable explanation for blackwater fever is an autoimmune reaction apparently caused by the interaction of the malaria parasite and the use of quinine. Blackwater fever is caused by heavy parasitization of red blood cells with Plasmodium falciparum .
The chloride ion is a well known quencher for quinine fluorescence. [2] [3] [4] Quenching poses a problem for non-instant spectroscopic methods, such as laser-induced fluorescence. Quenching is made use of in optode sensors; for instance the quenching effect of oxygen on certain ruthenium complexes allows the measurement of oxygen saturation in ...
Quinidine is a class IA antiarrhythmic agent used to treat heart rhythm disturbances. [1] It is a diastereomer of antimalarial agent quinine, [2] originally derived from the bark of the cinchona tree.
Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity.
