Summary
A modified MDMA compound shows significant potential for misuse by triggering the same reward pathways as the original drug. Lab tests revealed that mice actively sought out the compound and showed strong preferences for locations where they received it. The substance works by increasing dopamine levels in the brain, leading to reinforcing effects similar to other stimulants. These findings highlight important concerns about emerging drug variants that may bypass current detection methods.
Abstract
An N-protected methylenedioxymethamphetamine (MDMA), N-tert-butoxycarbonyl-3,4-methylenedioxymethamphetamine (t-BOC-3,4-MDMA), contains tert-butoxycarbonyl and can remain undetected in the illicit drug market. It is a new type of precursor substance that is not a chemical intermediate and can be converted into a controlled substance, MDMA, by deprotection of the N-tert-butoxycarbonyl group. Categorization of this chemical into a precursor or psychotropic substance is an issue because it is an unprecedented precursor that could have misuse potential. Although MDMA causes rewarding and reinforcing effect through dopaminergic transmission, the misuse potential of t-BOC-3,4-MDMA has not yet been characterized. Here, we aim to evaluate the misuse potential of t-BOC-3,4-MDMA. The response to the drug at a dose of 5 mg/kg was determined by a climbing test, and its rewarding and reinforcing properties were assessed through conditioned place preference and self-administration tests. In the conditioned place preference test, intraperitoneal administration of t-BOC-3,4-MDMA (5 mg/kg) significantly altered place preference in mice. In the self-administration models, t-BOC-3,4-MDMA induced drug-taking behavior at the dose of 0.5 mg/kg/infusion (intravenous) during 2 hr sessions under fixed-ratio schedules in mice. In addition, microdialysis experiments verified that t-BOC-3,4-MDMA impacted the dopamine levels of the brain (striatum) of rats. These experimental results indicate that t-BOC-3,4-MDMA has a potential for misuse. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
