1-[1-(2-Benzo[<i>b</i>]thiopheneyl)cyclohexyl]piperidine Hydrochloride (BTCP) Yields Two Active Primary Metabolites in Vitro: Synthesis, Identification from Rat Liver Microsome Extracts, and Affinity for the Neuronal Dopamine Transporter
1-[1-(2-Benzo[b]thiopheneyl)cyclohexyl]piperidine hydrochloride (BTCP, 1) and cocaine bind to the neuronal dopamine transporter to inhibit dopamine (DA) reuptake. However, on chronic administration, cocaine produces sensitization, but 1 produces tolerance. Because metabolites of 1 might be responsible for some of itspharmacological properties, we have identified the primary metabolites of 1 produced
