BD1063 or 1-[2-(3,4-dichlorophenyl)ethyl]-4-methylpiperazine is a selective sigma receptor antagonist, with a reported binding affinity of Ki = 9 ± 1 nM for the sigma-1 receptor and more than 49 times selectivity over the sigma-2 receptor.[1]

Consistent with other reported sigma receptor antagonists, pretreating Swiss Webster mice with BD1063 significantly decreases the convulsivity and lethality of cocaine.[1]

In other animal studies, BD1063 blocks the effects of MDMA,[2] and reduces alcohol intake in rodent models of alcoholism.[3]
