Scientific background

KCNQ2 (KV7.2) and KCNQ3 (KV7.3) are voltage-gated K+ channel subunits that underlie the neuronal M current1. Linopirdine, a putative cognition enhancing drug, increases acetylcholine (ACh) release in rat brain tissue and improves performance in animal models of learning and memory. In addition to ACh, Linopirdine has been shown to enhance the in vitro release of dopamine and 5-hydroxytryptamine (5-HT), and, to a lesser extent, γ-aminobutyric acid and glutamate2. The enhanced release of one or more neurotransmitters may account for the activity linopirdine displays in behavioral models of learning and memory3. The mechanism whereby linopirdine enhances acetylcholine release has been proposed to involve inhibition of the M-type K+ current (IM). Linopirdine is selective for IM with an IC50 value of 2.4 μM2.
