SB-334867 (SB 334867A) is an excellent,selective and blood-brain barrier permeable orexin-1 (OX1) receptor antagonist, shows selectivity over OX2 (pKb=7.4), 100-fold over 5-HT2B, 5-HT2C with pKi values of 5.4 and 5.3, respectively. SB-334867 reduces ethanol consumption and inhibits the acquisition of morphine-induced sensitization to locomotor activity in vivo.

    Description

    SB-334867 (SB 334867A) is an excellent,selective and blood-brain barrier permeable orexin-1 (OX1) receptor antagonist, shows selectivity over OX2 (pKb=7.4), 100-fold over 5-HT2B, 5-HT2C with pKi values of 5.4 and 5.3, respectively[1]. SB-334867 reduces ethanol consumption and inhibits the acquisition of morphine-induced sensitization to locomotor activity in vivo[2][3].

    In Vitro

    SB-334867 (100 pM- 10 μM) inhibits the orexin-A (10 nM) and orexin-B (100 nM)-induced calcium responses in a concentration-dependent manner, with apparent pKb values of 7.27±0.04 and 7.23±0.03, but has no effect on the calcium response elicited by UTP (3 μM), which activates an endogenous purinergic receptor in CHO-OX1 and CHO-OX2 cells[4].

    In Vivo

    SB-334867 (intraperitoneal injection; 20 mg/kg; 20 days) administers 15 min before morphine injection can significantly decrease the effect of the morphine challenge dose in mice in comparison with the sporadically morphine-treated group[2].
    SB334867 (intraperitoneal injection; 3, 10 and 30 mg/kg) significantly reduces ethanol intake relative to vehicle and does not effect water consumption in female P rats[3].
    SB334867 (intraperitoneal injection; 3, 10 and 30 mg/kg) reduces ethanol consumption at the 30 mg/kg dose, high dose suppresses sucrose intake relative to vehicle, and it results in lower blood ethanol concentrations (BECs) relative to both the 10 and 30 mg/kg doses[3].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
