Descrição geral

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.

Aplicação

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.

Previous studies have shown that the proton pump inhibitor omeprazole has antimalarial activity in vitro. The interactions of omeprazole with commonly used antimalarial drugs were assessed in vitro. Omeprazole and quinine combinations were synergistic; however, chloroquine and omeprazole combinations were

The effect of quinine on pyramidal cell intrinsic properties, extracellular potassium transients, and epileptiform activity was studied in vitro using the rat hippocampal slice preparation. Quinine enhanced excitatory post-synaptic potentials and decreased fast- and slow-inhibitory post-synaptic potentials. Quinine reduced the
