electroshock (MES) test and the psychomotor 6 Hz (32 mA) seizure models. Compound 33 showed the highest anticonvulsant activity in these models (ED50 MES = 79.5 mg/kg, ED50 6 Hz = 22.4 mg/kg). Compound 33 was also found to be effective in pentylenetetrazole-induced seizure model (ED50 PTZ = 123.2 mg/kg). In addition, 33 demonstrated effectiveness by decreasing pain responses in formalin-induced tonic
