Biological Activity

Description SB-334867 is a selective orexin-1 (OX1) receptor antagonist.
OX1 receptor [1]
In vitro

In CHO-OX1 cells, SB-334867 inhibits the orexin-A (10 nM) and orexin-B (100 nM)-induced calcium responses with pKB of 7.27 and 7.23 respectively, without effect on the UTP (3 microM)-induced calcium response. [1]

In vivo In both male and female rats, SB-334867 (30 mg/kg, i.p.) significantly reduces natural and orexin-A-induced food intake. [2] SB-334867 (2 mg/kg, i.v.) blocks the effects of antipsychotic drugs on dopamine neuronal activity in rats. [3] SB-334867 also inhibits the development of morphine analgesic tolerance in rats.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
