KRN4884
KRN4884 is a K+ channel opener. In the presence of intracellular ATP (1 mM), KRN4884 (0.1-3 μM) activates KATP channels in a concentration-dependent manner (EC50=0.55 μM).

IC50 & Target
EC50: 0.55 μM (KATP channel)[1]
In Vitro
KRN4884 (0.3 μM) shifts the concentration-response relationship for ATP-induced KATP channel inhibition to the right and slightly upward direction without altering the slope. After either the spontaneous or Ca2+-induced channel rundown, KRN4884 (1 and 3 μM) partially restores the KATP channel activity. Furthermore, the effect of KRN4884 is augmented by the presence of uridine 5′-diphosphate (3 mM). KRN4884 activates cardiac KATP channels through not only decreasing the sensitivity of the channel to ATP but also directly stimulating the opening of the channel. KRN4884 (0.3 and 3 μM) increases the outward current in a concentration-dependent manner, and the unitary current amplitudes are similar to that of KATP channels in the ATP-free solution[1].
