  • Title: Amelioration by glucose-6-phosphate and NADP of potato glycoalkaloid inhibition in cell, enzyme and liposome assays.
    Author: Roddick JG, Leonard AL.
    Journal: Phytochemistry; 1999 May; 51(1):23-7. PubMed ID: 10349728.
    Abstract:
    Lysis of human erythrocytes by 20 microM chaconine was reduced by 0.5 mM glucose-6-phosphate (G6P) and NADP. Both compounds caused approximately 50% inhibition of haemolysis at 1 mM. Glucose, glucose-1-phosphate, rhamnose, galactose and galactose-6-phosphate were ineffective; NAD was effective, although not to the extent of NADP. Of the tested sugars, only G6P reduced solanine-induced haemolysis. G6P also reduced the synergistic haemolytic action of solanine and chaconine in combination. G6P and NADP at or above 5 mM antagonised chaconine-induced betanin loss from excised red beet root discs; NADP was more effective than G6P. Disruption of PC/cholesterol liposomes by chaconine and inhibition of acetylcholinesterase by chaconine or solanine, were unaffected by up to 10 mM NADP or 50 mM G6P.
