An estimated 50 million people suffer epilepsy worldwide and 30% of the cases do not respond to current antiepileptic drugs (AEDs). Here, we report synthesis and anticonvulsant screening of new derivatives of nafimidone, a well-known member of (arylakyl)azole anticonvulsants. The compounds showed promising protection against maximal electroshock (MES)-induced seizures in mice and rats when administered via intraperitoneal (ip) and oral route. Especially, 5b, 5c, and 5i displayed outstanding activity in rats in MES test when given ip (ED50: 16.0, 15.8, and 11.8 mg/kg, respectively). Additionally, 5l was active against 6 Hz and corneal-kindled mice models. Behavioral toxicity of the compounds was very low and their therapeutic indexes were high compared to some currently available AEDs. A number of pharmaceutically relevant descriptors and properties were predicted for the compounds in silico in comparison with a set of known drugs. Favorable results were obtained such as good blood-brain barrier permeability and high oral absorption, as well as drug-likeness. 5l was found to show affinity to the benzodiazepine binding site of A-type GABA receptor via molecular docking simulations.
