Discovery of New 3-(Benzo[]Thiophen-2-yl)Pyrrolidine-2,5-Dione Derivatives as Potent Antiseizure and Antinociceptive Agents-In Vitro and In Vivo Evaluation.

: To address the unmet clinical needs in the treatment of epilepsy and pain, the continued development of more effective and safer anticonvulsants and analgesics is still necessary. Therefore, herein we report synthesis and antiseizure/antinociceptive evaluation of a focused series of 3-(benzo[b]thiophen-2-yl)pyrrolidine-2,5-dione derivatives. : The anticonvulsant properties were investigated in acute models of seizures, namely the maximal electroshock (MES), the 6 Hz (32 mA), and subcutaneous pentylenetetrazole (PTZ) seizure models, whereas analgesic activity was tested in the model of a tonic pain/formalin test and oxaliplatin-induced neuropathic pain (in CD-1-mice, i.
