ICA-105574 activates KCNH2. 4 / 4
| 4
reach
"It had been previously established by experiment that PD-118057 and ICA-105574, drugs that inhibits inactivation and thus increase hERG current, bind near F619 and L622 XREF_BIBR, XREF_BIBR."

reach
"ICA-105574 increases outward hERG1 currents (EC 50 of 0.5 muM, Hill slope of 3.3) far more than any other known agonist [XREF_BIBR]."

reach
"The primary mechanism by which ICA-105574 potentiates hERG channel activity is by removing hERG channel inactivation, because ICA-105574 (2 microM) shifts the midpoint of the voltage-dependence of inactivation by> 180 mV from -86 to +96 mV."

reach
"ICA-105574 (ICA), a 3-Nitro-n-(4-phenoxyphenyl) benzamide derivative activates hERG1 by strongly attenuating pore-type inactivation."
