Catalog Number: 0529
Alternate Names: 8-OH-DPAT hydrobromide
Chemical Name: (±)-8-Hydroxy-2-dipropylaminotetralin hydrobromide
Biological Activity
The standard selective 5-HT1A agonist. Also has moderate affinity for 5-HT7 receptors (pKi is 6.6 at the human 5-HT7 receptor expressed in HEK 293 cells). Reduces hippocampal 5-HT levels following systemic administration in rats in vivo. (R)-(+)-8-Hydroxy-DPAT hydrobromide (Cat. No. 1080) and 7-Hydroxy-DPAT hydrobromide (Cat. No. 0706) also available.
