2,4(5)-Diarylimidazoles: synthesis and biological evaluation of a new class of sodium channel blockers against hNa(v)1.2.

A small family of novel 2,4(5)-diarylimidazoles were prepared through a simple and efficient synthesis and evaluated as potential inhibitors of hNa(v)1.2 sodium channel currents. One member of this series (4) exhibited profound inhibition of Na(v)1.2 currents, emerging as a promising lead compound for further structure-activity relationship studies for the development of novel sodium channel blockers.
