Close

Tavapadon acts as a highly selective partial agonist of the dopamine D₁ receptor (K_i = 9 nM; IATooltip Intrinsic activity = 65%) and the dopamine D₅ receptor (K_i = 13 nM; IA = 81%).^[3][4][1] It has no significant affinity or functional activity at the D₂-like receptors (D₂, D₃, D₄) (K_i ≥ 4,870 to 6,720 nM).^[1] Tavapadon also shows biased agonism for G_s-coupled signaling at the D₁-like receptors.^[1][3]

As of December 2024, tavapadon has completed phase 3 clinical trials for Parkinson's disease.^[2]
