Abstract
The lipoperoxidation in plasma was the most accelerated by the addition of 8-hydroxyquinoline (8HQ)-Fe (III) chelate among all 8HQ-metal chelate systems examined. The same tendency was also observed for 5-chloro-7-iodo-8HQ (C)-Fe (III) chelate system. The activity of 8HQ-Fe (III) system in lipoperoxidation was the highest at [8HQ]:[Fe (III)]=1: 1. In quinoline derivatives, the ligands which have 8-hydroxyl group and high solubility in lipid were necessary for lipoperoxidation in plasma by Fe (III) chelate systems.
From above facts, both of the denaturation of nervous systems in SMON patients ad ministered with C and the antibiotic effects of 8HQ may be considered as the results of lipoperoxidation by C-Fe (III) chelate and 8HQ-Fe (III) chelate, respectively.
