In vitro study | SB-408124 binds to the hypocumin type 1 receptor (HcrtR1) with an Ki of 7.57 nM. Calcium mobilization studies have shown that SB-408124 is a functional antagonist of the OX1 receptor with specific affinity, SB-408124 50-fold more selective for the OX1 receptor than for the Orexin-2 receptor as measured in radioligand binding assays. Recent studies have shown that pretreatment of primary cultured rat astrocytes with SB-401824 followed by treatment with Orexin A significantly reduced the stimulation of Orexin A on basal and forskolin-activated cAMP production. |
In vivo study | Treatment of Wistar rats with 30 μg/10 μL SB-408124 intracerebroventricular administration reduced Orexin-A-induced water intake. Intraventricular administration of Orexin-A (30 μg/10 μL) blocked the increase in vasopressin (VP) levels induced by histamine or 2.5% NaCl treatment, pretreatment with SB-408124 can modulate this blocking effect. SB-408124((50 mM, 5 μl/h) intracerebroventricular administration blocked the increase in endogenous glucose production (EGP) induced by Bicuculline(BIC). |
