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.
