A Bright Ratiometric Dipyrene Probe for Functional Imaging of Condensate Microenvironments in Living Cells

Advanced Science, EarlyView.
Ratiometric dipyrene imaging resolves monomer (M) and excimer (E) channels and computes pixel‐wise E/M maps within biomolecular condensates, yielding physicochemical fingerprints shaped by coupled polarity‐related solvation and microviscosity. These spatial fingerprints enable quantitative phenotyping of cellular states, exemplified by separation of ...

Stimulation of Erythrocyte Cell Membrane Scrambling by Quinine

Cellular Physiology and Biochemistry, 2016
Background/Aims: The analkaloid drug quinine is utilized mainly for the chemoprophylaxis of malaria. The multiple side effects of quinine include hemolytic anemia and hemolytic uremic syndrome, disorders involving suicidal erythrocyte death or eryptosis,

Drug-induced immune thrombocytopenia: Mapping of the drug binding site to the membrane-proximal region of platelet GPIX

Platelets, 2019
Drug-induced Immune thrombocytopenia (DIT) is a common complication of several medications, including commonly used antibiotics. The most widely studied DIT is caused by quinine. In DIT, antibodies predominantly bind to the platelet membrane glycoprotein

Demethylation of Quinine Using Anhydrous Aluminium Trichloride

Journal of Mathematical and Fundamental Sciences, 2013
Quinine is a natural alkaloid having a methoxy group bound to quinoline ring and an allyl group bound to quinuclidine ring. Demethylation of quinine applying strong acid such as HBr or HI at high temperature was unsuccessful. The aim of this research was
