Description

GSK1059865 is a potent orexin 1 receptor antagonist.

IC50 & Target

Orexin 1 receptor[1]
In Vivo

Treatment with GSK1059865 significantly decreases ethanol drinking in a dose-dependent manner in CIE-exposed mice. In contrast GSK1059865 decreases drinking in air-exposed mice only at the highest dose used. There is no effect of GSK1059865 on sucrose intake[1]. GSK1059865 (0.3 nM-10 nM) produces non-surmountable antagonism with a dose-dependent rightward shift of the OXA EC50 and a concomitant decrease of the agonist maximal response. The calculated pKB value is 8.77±0.12 for GSK1059865. GSK1059865 (0.1-3.3 μM) produces a classical surmountable profile with parallel rightward shift of the OXA EC50 without depression of the agonist maximal response[2]. Intraperitoneal administration of GSK1059865 produces a region-dependent inhibition of yohimbine-induced relative cerebral blood volume response. The administration of GSK1059865 per se produces a weak relative cerebral blood volume increase in several brain regions. GSK1059865-pretreated animals exhibit slightly higher baseline mean arterial blood pressure values than controls[3].

In Vivo:

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  30 % SBE-β-CD

    Solubility: 3.33 mg/mL (7.63 mM); Clear solution; Need ultrasonic

  • Protocol 2

    Add each solvent one by one:  30% PEG300    70% (10% HP-β-CD in Saline)

    Solubility: 5 mg/mL (11.46 mM); Suspended solution; Need ultrasonic

Animal Administration
[1][2]

Rats: GSK1059865 is dissolved in 0.5% HPMC (w/v) in distilled water and administered by gavage at doses of 10 and 30 mg/kg to rats. Drug or vehicle is administered 1 h before access to highly palatable food[2].

Mice: During baseline and the first 5 test cycles following chronic intermittent ethanol (or air) exposure, mice receive vehicle (saline) injections (i.p.; 0.01 ml/g body weight) 30 minutes before drinking ethanol. On test cycles 6 and 7 mice receive vehicle or GSK1059865 (10, 25, 50 mg/kg) before given access to ethanol 15% v/v (Test 6) or sucrose 5% w/v (Test 7) versus water. GSK1059865 is dissolved in saline and TWEEN 80 (0.5 % v/v) as vehicle[1].

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.
