Application: Quinine was used in the following processes:

• To study its in vitro antimalarial activity in combination with omeprazole.
• To analyze its effect on viscosity and friction of saliva.
• As a test agent to study its impact on the accumulation of the fluorescent P-glycoprotein (Pgp) substrates in P-glycoprotein overexpressing breast cancer cells.
• To study its influence on the pyramidal cell intrinsic properties, extracellular potassium transients, and epileptiform activity in vitro.
• As a reference compound to identify alkaloids by phytochemical screening of Deianira erubescens, Strychnos pseudoquina and Remijia ferruginea plants.
Biochem/physiol Actions: Potassium channel blocker
General description: Quinine, also known as 6′-Methoxycinchonidine is a fluorescent reagent. The quantum yield of Quinine is 23% higher at 390 mµ excitation wavelength than at 313 mµ. The fluorescence polarization in the emission band of quinine in a rigid medium arises from two singlet states simultaneously. The emission spectra of quinine or 6-methoxyquinoline shifts towards the red zone when excited at 390 mµ.
