Description; Application; BD 1047, a selective, putative σ1 receptor antagonist, is used in sigma receptor research to help differentiate and characterized the function and role of the sigma1 receptor versus other sigma receptor subtypes. BD 1047 is used to help define the role of σ1 receptors in neurological processes.; Packaging; 5, 25 mg in glass bottle; Biochem/physiol Actions; BD-1047 is a selective, putative σ receptor antagonist with antidystonic activity. BD-1047 has >50-fold selectivity at σ1 over σ2 and also >100-fold selectivity over opiate, phencyclidine, muscarinic, dopamine, α1- & α2-adrenoceptor, 5-HT1, and 5-HT2. Though s receptor antagonism is consistent with antipsychotic, especially anti-schizophrenic, activity, BD-1047 shows only modest activity in animal screens for antipsychotics.
