Actions biochimiques/physiologiques

The new diphenylurea compound 1,3-bis-(2-hydroxy-5-trifluoromethyl-phenyl)-urea (NS1643) was tested in hERG channel. In Xenopus laevis oocytes, NS1643 increased both steady-state and tail current at all voltages tested. The EC50 value for hERG channel activation was 10.5 μM. The effect could be reverted by application of the specific hERG channel inhibitor 4′-[[1-[2-(6-methyl-2-pyridyl)ethyl]-4-piperidinyl]carbonyl]-methanesulfonanilide (E-4031) at 100 nM. Application of NS1643 also resulted in a prolonged postrepolarization refractory time. hERG channel activation by small molecules such as NS1643 increases the repolarization reserve and presents a new antiarrhythmic approach.
