8-OH-DPAT is a serotonin 5-HT1A receptor agonist of the 2-aminotetralin family which was developed in the 1980s and has been widely used to study the function of the 5-HT1A receptor. [1] [2] It was one of the first major 5-HT1A receptor full agonists to have been discovered.

Contents

Originally believed to be selective for the 5-HT1A receptor, 8-OH-DPAT was later found to act as a serotonin 5-HT7 receptor agonist and serotonin reuptake inhibitor or releasing agent as well. [3] [4] [5] [6] [7]

In animal studies, 8-OH-DPAT has been shown to possess antidepressant, [8] anxiolytic, [9] serenic, [10] anorectic, [11] antiemetic, [12] hypothermic, [13] hypotensive, [14] bradycardic, [14] hyperventilative, [15] [16] [17] and analgesic effects. [18]
