Selected examples from three series of isomeric (alkylthio)-1, 2, 4-triazoles were prepared and examined for anticonvulsant activity versus strychnine-, maximal-electroshock-, pentylenetetrazole-, and 3-mercaptopropionic-acid-induced seizures in mice. A number of B- aryl-3-(alkylthio)-4H-1, 2, 4-triazoles were selective antagonists of strychnine-induced convulsions. The isomeric 3-aryl-5-(alkylthio)-and 5-aryl-3-(alkylthio)-lH-l, 2, 4-triazoles ...
