8-Hyroxy-2-Dipropylaminotetralin Hydrobromide (8-OH-DPAT) is a chemical predominantly used in research settings. It is widely regarded as the first identified complete agonist of the 5-HT1a receptor, for which it has a Ki = 3.18 nM. 8-OH-DPAT also acts as an agonist of the 5-HT7 receptor, and as a substrate of the Sodium dependent serotonin transporter (SERT). Although it has never progressed to human clinical trials 8-OH-DPAT has been studied in animal models for a number of conditions both for its own potential and as a benchmark for other compounds.

Sample Use Guides

Traumatically brain injured rats were given a single intraperitoneal dose of 8-OH-DPAT (0.1, 0.5, or 1.0 mg/kg) 15 minutes after controlled cortical impact. Motor and cognitive functions were tested on post operative days 1-5 and 14 -18 respectively. Hippocampal cell survival and cortical lesion volume were recorded at 4 weeks. It was observed that 0.5 mg/kg of 8-OH-DPAT conferred neuroprotective effects by attenuating spatial acquisition deficits and reducing hippocampal CA(3) cell loss.
Route of Administration: Intraperitoneal
In Vitro Use Guide
Monkey kidney cells (cos-7) were grown and transiently transfected with the vector for the human 5-HT7 receptor. Cells were incubated for 30 minutes at 37 degree Celsius with 5 nM [3H] 5-HT and 7 different concentrations of 8-OH-DPAT. A Ki value of 466 nM was recorded for 8-OH-DPAT.
