Background:

BD 1063 dihydrochloride is an antagonist of σ-1 receptor with Ki value of 9.15 nM [1].

σ-receptor is a type of opioid receptor. There are two subtypes of σ-receptor: σ-1 and σ-2.σ-1 receptor plays an important role in stimulating dopamine release and modulating the actions of cocaine [2].

BD 1063 dihydrochloride is a σ-1 receptor antagonist with Ki values of 9.15 and 449 nM for σ-1 receptor and σ-2 receptor, respectively. BD1063 reduced the dystonia induced by haloperidol and di-o-tolylguanidine (DTG) in a dose-dependent way [1].

In mice, BD1063 inhibited up-regulation of fra-2 and σ-1 receptor induced by cocaine in whole brain, cortex and striatum [2]. In mice, BD1063 significantly inhibited convulsions, lethality and locomotor stimulatory effects induced by cocaine [3]. In two excessive drinking rat models, BD-1063 reduced ethanol self-administration in a dose-dependent way and inhibited the expression of σ-1 receptor in the nucleus accumbens [4]. In mice, BD-1063 reversed thermal (radiant heat) hyperalgesia and inflammatory mechanical (paw pressure) in a dose-dependent way. However, BD-1063 had no effect on thermal hyperalgesia in σ1 knockout (σ1-KO) mice. These results suggested that σ1 receptor played an important role in inflammatory hyperalgesia [5].
