Evaluation Of Antioxidant Activity Of 1, 2, 4-Triazole Derivatives With Morpholine Moiety
Hacettepe University Journal of the Faculty of Pharmacy, 2022 The aim of the work was to study the antioxidant activity of 4-R-3- (morpholinomethyl)-4H-1,2,4-triazole-5-thioles and their alkyl derivatives in vitro using the method of non-enzymatic initiation of lipid peroxidation. Among the 45 compounds studied, 8 showed varying degrees of AOA.
