Bioactivity
Chemical Properties
| Description | EMPA is a selective, high-affinity and reversible antagonist of orexin OX2 receptor(human and rat OX2-HEK293 membranes with KD values of 1.1 and 1.4 nM respectively) |
| In vitro | EMPA displaces the EMPA binding from cell membranes containing human and rat OX2 receptors, with Ki values of 1.10±0.24 nM and 1.45±0.13 nM, respectively. EMPA shows an IC50=5.75 μM, Ki=2.63 μM, and IC50=12.8 μM, Ki=5.8 μM in the binding assay at human and mouse V1a receptors, respectively. In CHO(dHFr-) cells stably expressing hOX2 receptors, EMPA inhibits orexin-A-or orexin-B-evoked [Ca2+]i response with IC50s of 8.8±1.7 nM and 7.9±1.7 nM, respectively.EMPA competitively antagonizes orexin-A-and orexin-B-evoked accumulation of inositol phosphates (IP) at hOX2 receptors with pA2 values of 8.6 and 8.8 respectively. |
| In vivo | 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.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. |

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
