5-Aryl-1,3,4-thiadiazole derivatives were synthesized and tested for anticonvulsant activity using the pentylenetetrazole-induced lethal convulsion test. The results showed that 2-amino derivatives have anticonvulsant activity (LD50 > 500 mg kg -1 ) and this effect was not mediated through benzodiazepine receptors. The fluoro electron-withdrawing substituent on the phenyl ring did not potentiate the activity of the compounds.
