ML297

Biochem/physiol Actions

ML297 (VU0456810) is the first potent and selective activator of the GIRK potassium channel. The G protein-coupled inwardly-rectifying potassium channels (GIRKs 1-4) are widely distributed broadly in the central nervous system (GIRKs 1-3) and also found in the heart (GIRK-4). ML297 activates GIRK channels containing a GIRK1 subunit, and does not activate channels without a GIRK1 subunit or the closely related potassium channel Kir2.1 or voltage-gated potassium channels. ML297 has been shown to activate GIRK1/2 with a potency of ~160 nM and also to activate GIRK channels comprising of GIRK1/3 and GIRK1/4 subunit combinations. ML297 was active in two in vivo models of epilepsy, and showed equal or greater efficacy than the anti-seizure medication, sodium valproate.
