Description: 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. Target: Others. Smiles: COc1ccc(cc1)-c1cc(N)c(s1)C(N)=O

AA43279 is an activator of voltage-gated sodium channel 1.1 (Nav1.1, EC50 = 9.5 µM in a patch-clamp assay using HEK293 cells expressing the human channel). It is selective for Nav1.1 over Nav1.4 and Nav1.7 at 30 µM but also activates Nav1.2, Nav1.5, and Nav1.6 (EC50s = 22.8, 14.4, and 11.6 µM, respectively). AA43279...
