Possible Involvement of Hallucinogenic Effects in the Aversive Effects Induced by Kappa‐Opioid and 5‐ HT 2A / 2C Receptor Agonists in Mice

Neuropsychopharmacology Reports November 23, 2025 Hideaki Kato, Yoshimi Ichimaru, Masaaki Kurihara et al. 1 citation

AIM: The regulation of new psychoactive and dangerous abused substances is very important for the prevention of drug abuse. A simple and effective evaluation method using laboratory animals is needed to regulate designated drugs with high accuracy and speed. METHODS: receptor agonist 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), which have a similar mechanism of action to...

[Drug Dependence and Cytotoxicity of Law-evading Drugs: Their Identities Explored from Basic Research].

Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan 2016 Masahiko Funada

Cases of people experiencing disturbed consciousness or dyspnea, causing traffic accidents, or requiring ambulance transport to hospital due to abuse of law-evading chemical substances have become a serious social problem in Japan. Most law-evading herbal products are marketed as incense or herbs and consist of finely chopped, dry vegetative matter mixed with chemical substances (drugs)....

5-Methoxy-N,N-diisopropyltryptamine (Foxy), a selective and high affinity inhibitor of serotonin transporter.

Toxicology Letters April 5, 2007 Chiharu Sogawa, Norio Sogawa, J Tagawa et al. 47 citations

5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT) is a synthetic orally active hallucinogenic tryptamine derivative, known also as Foxy or Foxy methoxy. However, few studies have examined its effects in vitro. In the present study, we investigated the actions of 5-MeO-DIPT against monoamine neurotransmitter transporters, including the transporters for dopamine (DAT), norepinephrine (NET), and...

Oxidative metabolism of 5-methoxy-N,N-diisopropyltryptamine (Foxy) by human liver microsomes and recombinant cytochrome P450 enzymes.

Biochemical Pharmacology April 28, 2006 Shizuo Narimatsu, Rei Yonemoto, Keita Saito et al.

In vitro quantitative studies of the oxidative metabolism of (5-methoxy-N,N-diisopropyltryptamine, 5-MeO-DIPT, Foxy) were performed using human liver microsomal fractions and recombinant CYP enzymes and synthetic 5-MeO-DIPT metabolites. 5-MeO-DIPT was mainly oxidized to O-demethylated (5-OH-DIPT) and N-deisopropylated (5-MeO-IPT) metabolites in pooled human liver microsomes. In kinetic studies,...
