Quinine hydrochloride is an alkaloid extracted from cinchona bark and exhibits oral activity, acting as a potassium channel inhibitor. Quinine hydrochloride modulates the tolerance of red blood cells and presents dose-dependent toxicity and embryonic effects. Quinine hydrochloride is a typical hemolysin that directly lyses red blood cells, with cellular components of red blood cell membranes as its action targets. Quinine hydrochloride disrupts red blood cell membranes and induces hemolysis at high concentrations, while merely weakening the anti-hemolytic capacity of red blood cells at low concentrations. Quinine hydrochloride continuously reduces red blood cell tolerance after in vivo administration, and high doses can also alter blood cell counts. Quinine hydrochloride can be applied to researches related to red blood cell hemolysis, cancer and malaria.
