KB130015 is a novel activator of hERG1 potassium channels, blocking native and recombinant hERG1 channels at high voltages, but activating them at low voltages.
VU0529331 is a modestly selective non-GIRK1-containing G protein-gated, inwardly-rectifying, potassium channel (non-GIRK1/X) activator, with EC50s of 5.1 ?M and 5.2 ?M for GIRK2 and GIRK1/2 in HEK293 cells, respectively, also effective on GIRK4 homomeric channel.
CLP290 is an orally available activator of the neuron-specific K+-Cl? cotransporter KCC2, displays potential for treatment of a wide range of neurological and psychiatric indications.
P-1075 is a potent activator of sulfonylurea receptor 2-associated ATP-sensitive potassium channels (SUR2-KIR6), with an EC50 value of 45 nM for SUR2B-KIR6 channel activation.
RPR-260243 is a novel activator of HERG; modifies HERG currents inhibited by dofetilide (IC50 = 58 nM); little effect on HERG current amplitude and no significant effects on steady-state activation parameters or on channel inactivation processes.
NS5806, a potent potassium current activator, increases KV4.3/KChIP2 peak current amplitudes with an EC50 of 5.3 μM. NS5806 slows KV4.3 and KV4.2 current dacay in channel complexes containing KChIP2.
