Application

SB-277011-A hydrochloride hydrate has been used:
  • as a dopamine D3 receptor-selective antagonist in rats to test its effect on 4-propyl-9-hydroxynaphthoxazine ([3H]-(+)-PHNO) radiotracer in cerebellum L9/10 and striatumPMID 25837930
  • as an acetylcholine inhibitor to test its negative allosteric modulation on Ascaris suum nicotinic acetylcholine receptor (Asu-ACR-16) expressed in Xenopus oocytes and its inhibitory effect on locomotion in Caenorhabditis elegansPMID 27054065
  • to test its effect on alcohol consumption in micePMID 25257287

SB-277011-A hydrochloride hydrate may be used in D3 dopamine receptor-mediated cell signaling studies.

Biochem/physiol Actions

SB-277011-A is a potent, selective brain-penetrant D3 dopamine receptor antagonist; 80-100x selective for D3 over D2; pKi = 7.95 for hD3 receptor.
SB-277011-A is the most selective D3 dopamine receptor antagonist.
The D3 dopamine receptor antagonist, SB-277011-A inhibits the cocaine-seeking behavior and cocaine-enhances brain stimulation reward in in rats.[1][2] It decreases drug-seeking behavior and may be useful in treatment of cocaine and methamphetamine addiction.[1][2][3]
