A convenient Ni(II)-catalyzed C?C and C?N cascade coupling reaction was developed to directly access various 2,4-disubstituted imidazoles. The reaction scope covers a variety of aryl and aliphatic substitutions, which demonstrate moderate-to-excellent yie

2,4(1H)-Diarylimidazoles have been previously shown to inhibit hNa V1.2 sodium (Na) channel currents. Since many of the clinically used anticonvulsants are known to inhibit Na channels as an important mechanism of their action, these compounds were tested in two acute rodent seizure models for anticonvulsant activity (MES and scMet) and for sedative and ataxic side effects. Compounds exhibiting antiepileptic activity were further tested to establish a dose response curve (ED50). The experimental data identified four compounds with anticonvulsant activity in the MES acute seizure rodent model (compound 10, ED50 = 61.7 mg/kg; compound 13, ED 50 = 46.8 mg/kg, compound 17, ED50 = 129.5 mg/kg and compound 20, ED50 = 136.7 mg/kg). Protective indexes (PI = TD 50/ED50) ranged from 2.1 (compound 10) to greater than 3.6 (compounds 13, 17 and 20). All four compounds were shown to inhibit hNa V1.2 in a dose dependant manner. Even if a correlation between sodium channel inhibition and anticonvulsant activity was unclear, these studies identify four Na channel antagonists with anticonvulsant activity, providing evidence that these derivatives could be potential drug candidates for development as safe, new and effective antiepileptic drugs (AEDs).
