RS134-49 is a tetrahydropyridine derivative related to psychedelic tryptamines which acts as a 5-HT2A receptor agonist, with a 5-HT2A Ki of 11.5nM and an EC50 of 22nM. It is a biased agonist selective for activation of the Gq coupled signalling pathway with weaker activation of the β-arrestin 2 coupled pathway, but shows a more balanced profile than related compounds such as (R)-69 .[ 1] [ 2]
