Actions biochimiques/physiologiques

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.

The central circadian regulator within the suprachiasmatic nucleus transmits time of day information by a diurnal spiking rhythm driven by molecular clock genes controlling membrane excitability. Most brain regions, including the hippocampus, harbor similar intrinsic circadian transcriptional machinery, but whether

G-protein-gated inwardly rectifying K+ (GIRK) channels are essential effectors of inhibitory neurotransmission in the brain. GIRK channels have been implicated in diseases with abnormal neuronal excitability, including epilepsy and addiction. GIRK channels are tetramers composed of either the same subunit

G-protein coupled receptors (GPCRs) are versatile cellular sensors for chemical stimuli, but also serve as mechanosensors involved in various (patho)physiological settings like vascular regulation, cardiac hypertrophy and preeclampsia. However, the molecular mechanisms underlying mechanically induced GPCR activation have remained elusive.
