5-OH-DPAT is a synthetic compound that acts as a dopamine receptor agonist with selectivity for the D2 receptor and D3 receptor subtypes.[2][3] Only the (S)-enantiomer is active as an agonist, with the (R)-enantiomer being a weak antagonist at D2 receptors.[4] Radiolabelled 11C-5-OH-DPAT is used as an agonist radioligand for mapping the distribution and function of D2 and D3 receptors in the brain,[5][6] and the drug is also being studied in the treatment of Parkinson's disease.[7][needs update]
