QO-83 is a potent activator of the KCNQ2 (Kv7.2) voltage-gated potassium channel, exhibiting an EC50 of 0.56 μM. It binds to a specific hydrophobic pocket within the KCNQ2-CaM complex in its closed conformation, resulting in a negative shift in the voltage-dependent activation curve. This mechanism enhances the voltage sensitivity of KCNQ2 channels. QO-83 is a valuable tool for research into the mechanisms underlying epilepsy and related ion channel disorders.
