RU-24213, also known as 3-hydroxy-N-propyl-N-(phenylethyl)phenethylamine, is a dopamine receptor agonist of the phenethylamine family related to dopamine.^[1]^[2]^[3] It is a selective dopamine D₂-like receptor agonist.^[1]^[3] Subsequently, however, RU-24213 was found to also act as a potent κ-opioid receptor (KOR) antagonist.^[2]^[4] It led to the development of the diphenylethylamine series of KOR ligands.^[4]^[5] RU-24213 was first described in the scientific literature in 1978.^[4]^[6]
