Determination of the pKa value of some 1,2,4-triazol derivatives in forty seven different solvents using semi-empirical quantum methods (PM7, PM6, PM6-DH2, RM1, PM3, AM1, and MNDO) by MOPAC computer program [PDF]
In this study, we calculated the enthalpy (?H, kcal/mol), entropy (?S, cal/K.mol) and free energy (?G, kcal/mol) thermodynamic values of each molecule for forty-seven different solvent media according to semi-empirical quantum methods (PM7, PM6, PM6-DH2,

Evaluation Of Antioxidant Activity Of 1, 2, 4-Triazole Derivatives With Morpholine Moiety
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.
