LY-456219 is a potent and selective serotonin 5-HT_1D receptor antagonist which has been used in research to study the function of presynaptic 5-HT_1D autoreceptors. LY-456219 lacks significant affinity for the 5-HT_1B, α₁ adrenergic, and dopamine D₂ receptors. ^[1]^[2] It is an enantiomer of LY-456220.
