investigation of antioxidant activity of quinoline in philippines
[Investigation of antioxidant activity of quinoline
Antioxidant activity of new synthetic physiologically active substances (thioderivatives of quinoline) are investigated using the complex of primary estimation techniques in vitro and in vivo. It is shown that the compounds investigated display both antiradical and anti-oxidative activity, most strongly delineated for the compounds with methoxygroup in the 6th position of quinoline cycle.
