| Hazard Information | Back Directory | [Description]
EMPA is an orexin 2 receptor (OX2R) antagonist (Ki = 1.1 nM). It is selective for OX2R over OX1R (Ki = 900 nM). EMPA inhibits orexin-A- and orexin-B-induced calcium mobilization (IC50s = 8.8 and 7.9 nM, respectively) and increases orexin-A- and orexin-B-induced inositol phosphate accumulation (EC50s = 1.1 and 2.4 nM, respectively) in CHO(dHFr-) cells expressing recombinant human OX2R. It reduces spontaneous locomotor activity and orexin-B-induced hyperlocomotion in mice when administered at doses ranging between 10 and 300 mg/kg. | [Uses]
EMPA is a novel high-affinity, selective antagonist for the OX2 receptor. | [in vivo]
EMPA (1-300 mg/kg; i.p.) dose-dependently reverses this [Ala11,D-Leu15]orexin-B-induced hyperlocomotion without itself significantly affecting locomotor activity (LMA) in male NMRI mice[1].
EMPA (3-30 mg/kg; i.p.) induces a significant and dose-dependent reduction in the baseline LMA in france and male Wistar rats. EMPA (3-30 mg/kg; i.p.) demonstrates a clear dose-dependent inhibition of spontaneous activity as compared with vehicle-treated animals[1]. | Animal Model: | Male NMRI mice (20-30 g)[1] | | Dosage: | 1, 3, 10, 30, 100, 300 mg/kg | | Administration: | Injected i.p. at a volume of 10 mL/kg | | Result: | Dose-dependently reversed this [Ala11,D-Leu15]orexin-B-induced hyperlocomotion without itself significantly affecting LMA. |
| Animal Model: | France and Male Wistar rats (196-237 g)[1] | | Dosage: | 3, 10, 30 mg/kg | | Administration: | Injected i.p. at a volume of 5 mL/kg | | Result: | Induced a significant and dose-dependent reduction in the baseline LMA.
Demonstrated a clear dose-dependent inhibition of spontaneous activity as compared with vehicle-treated animals. |
