BD1063 dihydrochloride | Selective sigma-1 antagonist

BD1063 (206996-13-6) is potent and selective sigma-1 antagonist (IC50’s: σ1 = 9nM, σ2 = 449nM).1 BD1063 abolished mechanical and thermal hyperalgesia in mice with carrageenan-induced acute inflammation by enhancing the action of endogenous opioid peptides of immune origin in a σ1 dependent manner.2 BD1063 potentiated µ-opioid antinociception in mice in a sigma-dependent manner.3 BD-1063 has been used in animal models to successfully treat compulsive eating4 and excessive ethanol drinking5.
