| Katalog-Nr.GC30888 |
8-OH-DPAT (8-Hydroxy-DPAT) ist ein potenter und selektiver 5-HT-Agonist mit einem pIC50 von 8,19 fÜr 5-HT1A und einem Ki von 466 nM fÜr 5-HT7; 8-OH-DPAT (8-Hydroxy-DPAT) bindet schwach an 5-HT1B (pIC50, 5,42), 5-HT (pIC50 <5).

8-OH-DPAT, at a pIC50 of 8.19, exhibits robust and specific agonistic activity on 5-HT1A receptors, indicating high selectivity. However, 8-OH-DPAT shows only weak binding affinity towards 5-HT1B receptors (pIC50, 5.42) and minimal binding to 5-HT receptors (pIC50
Pretreatment of 8-OH-DPAT over the concentration range of 1-100µM significantly inhibited the H2O2 -induced neuronal cell death[3].8-OH-DPAT(10 µM;24 h) reduces lipofuscin accumulation in cultured RPE cells[4].
In rats administered with 8-OH-DPAT(0-0.1 mg/kg; s.c.;2h) and provided with wet mash, feeding and activity frequencies were increased, while resting and total grooming behaviors were inhibited in non-deprived conditions[5]. 8-OH-DPAT(0.5 mg/kg；s.c) enhanced QUIN' (an agonist quinpirole) and HAL's(a potent D₂ antagonist haloperidol) disruption of pup retrieval and pup preference, reversed the increase in hovering over pups induced by HAL in mice[6]. 8-OH-DPAT(0.2 and 0.4mg/kg i.p.) reduces competition from contextual but not discrete conditioning cues[7]. Systemically injected 8-OH-DPAT (0.4 mg/kg) decreased extracellular 5-HT levels in the medial preoptic area (MPOA) as measured by in vivo microdialysis[8].
