Lu AE98134, an activator of voltage-gated sodium channels, acts as a partly selective Nav1.1 channels positive modulator. Lu AE98134 also increases the activity of Nav1.2 and Nav1.5 channels but not of Nav1.4, Nav1.6 and Nav1.7 channels. Lu AE98134 can be used to analyze pathophysiological functions of the Nav1.1 channel in various central nervous system diseases, including cognitive restoring in schizophrenia, et al[1].
AA43279 is a novel selective Nav1.1 activator, increasing the firing activity of parvalbumin-expressing, fast-spiking GABAergic interneurons and increasing the spontaneous inhibitory post-synaptic currents (sIPSCs) recorded from pyramidal neurons.
Potent blocker of voltage-gated sodium channels (IC50 values are 0.6, 42, and 72 nM for NaV1.2, NaV1.3 and NaV1.5 respectively). Blocks inward sodium currents in a voltage-dependent manner.
Potent Nav1.7 blocker (IC50 = 2.5 nM). Also inhibits Nav1.1, Nav1.2, Nav1.3 and Nav1.6 in the nanomolar range. Exhibits no effects on Cav channels or nAChR at 5 μM. Demonstrates analgesic activity in vivo; antagonizes effects of scorpion-venom toxin OD1 a
