RS134-49, also known as 4-methyl-THPI, is a tetrahydropyridinylindole (THPI) derivative related to psychedelic tryptamines which acts as a 5-HT_2A receptor agonist, with a 5-HT_2A K_i of 11.5nM and an EC₅₀ of 22nM. It is a biased agonist selective for activation of the G_q 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]}
