(R)-69

(R)-69 (3IQ) is a tetrahydropyridine derivative which acts as a 5-HT_2A receptor agonist, with 4.6x selectivity over 5-HT_2B and 49x selectivity over 5-HT_2C. It has a 5-HT_2A K_i of 680nM and an EC₅₀ of 41nM. (R)-69 is a biased agonist selective for activation of the G_q coupled signalling pathway, with much weaker activation of the β-arrestin 2 coupled pathway. In animal studies it produces antidepressant-like activity but without producing the head-twitch response associated with psychedelic effects.^[1]
