QO 58
Based on 1 Customer Validation
QO 58 is a potent modulator of K(v)7 channels. QO-58 increases the current amplitudes, shifts the voltage-dependent activation curve in a more negative direction and slows the deactivation of K(v)7.2/K(v)7.3 currents. QO-58 has the potential for the research of diseases associated with neuronal hyperexcitability.
