说明

一般描述

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.[1]
 

应用

Quinine was used in the following processes:
  • To study its in vitro antimalarial activity in combination with omeprazole.[2]
  • To analyze its effect on viscosity and friction of saliva.[3]
  • 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.[4]
  • To study its influence on the pyramidal cell intrinsic properties, extracellular potassium transients, and epileptiform activity in vitro.[5]
  • As a reference compound to identify alkaloids by phytochemical screening of Deianira erubescens, Strychnos pseudoquina and Remijia ferruginea plants.[6]
