NLX-266
NLX-266 is a biased agonist of the serotonin 5-HT1A receptor. It acts specifically as a very-high-affinity and selective ERK1/2-biased serotonin 5-HT1A receptor agonist (Ki = 0.0447 nM; EC50Tooltip half-maximal effective concentration = 0.437 nM; EmaxTooltip maximal efficacy = 94%), with selectivity for ERK1/2 signaling over multiple other pathways.
