Application

SR144528 has been used as a cannabinoid CB2 receptor antagonist:
  • to study its blocking effect on the anti-dyskinetic functionality of HU-308
  • to study its effects on spontaneous excitatory postsynaptic currents (sEPSCs) from the globus pallidus neurons
  • to analyze its effect on the gastric emptying in rats

Biochem/physiol Actions

SR144528 is a potent and highly selective cannabinoid CB2 receptor inverse agonist. SR144528 exhibited a Ki of 0.6 nM at CB2 compared to 400 nM at the related CB1 receptor.

The globus pallidus receives its major glutamatergic input from the subthalamic nucleus and subthalamic nucleus neurons synthesize CB1 cannabinoid receptors. The hypothesis of the present work was that CB1 receptors are localized in terminals of subthalamo-pallidal glutamatergic axons and that
