ML252 is a potent, brain penetrant potassium channel Kv7.2 (KCNQ2) inhibitor.
ML252 is a potent, brain penetrant potassium channel Kv7.2 (KCNQ2) inhibitor with an IC50 of 69 nM. ML252 is only slightly selective over KCNQ3 and KCNQ4 but is over 40-fold selective for KCNQ2 vs KCNQ1, unlike other KCNQ inbhibitors currently used. ML252 was also selective vs. >68 tested GPCRs, ion channels, and transporters. Potassium channel Kv7.2 has become a new target for Alzheimer′s Disease drug research because inhibiting it enhances acetylcholine release. SAR studies showed a small structural change from ethyl group to hydrogen resulted in a functional shift from antagonist to agonist activity (37, EC50 of 170 nM), suggesting an interaction at a critical site for controlling KCNQ2 channel gating.

Brainstem networks that control regular tidal breathing depend on excitatory drive, including from tonically active, CO2/H+-sensitive neurons of the retrotrapezoid nucleus (RTN). Here, we examine intrinsic ionic mechanisms underlying the metronomic firing activity characteristic of RTN neurons. In mouse brainstem
