8-OH-DPAT is a research chemical of the aminotetralin chemical class which was developed in the 1980s and has been widely used to study the function of the 5-HT1A receptor. It was one of the first major 5-HT1A receptor full agonists to be discovered.

Originally believed to be selective for the 5-HT1A receptor, 8-OH-DPAT was later found to act as a 5-HT7 receptor agonist and serotonin reuptake inhibitor/releasing agent as well.[2][3][4][5][6]

In animal studies, 8-OH-DPAT has been shown to possess antidepressant,[7] anxiolytic,[8] serenic,[9] anorectic,[10] antiemetic,[11] hypothermic,[12] hypotensive,[13] bradycardic,[13] hyperventilative,[14][15][16] and analgesic effects.[17]
