5-MeO-DIPT, a synthetic hallucinogenic tryptamine, acts as a competitive inhibitor of the serotonin transporter (SERT), blocking serotonin uptake with high affinity and at concentrations similar to cocaine. It does not stimulate reverse transport of serotonin through SERT, and it prevents the serotonin-releasing action of methamphetamine. At high concentrations, the compound is toxic to cells, but this toxicity is not influenced by SERT expression. These findings clarify the serotonergic mechanism of 5-MeO-DIPT.

The psychedelic compound 2C-B, involved in human drug abuse and overdose cases, was studied in rats to determine its distribution and kinetics after subcutaneous injection. The drug had an estimated half-life of 1.1 hours and a volume of distribution of 16 L/kg. 2C-B entered the brain without significant delay, and its brain-to-serum ratio peaked at 13.9, remaining above 6.5 for six hours. The lungs showed a tendency to retain the drug and release it gradually over time, similar to the brain. The major metabolite 2H5M-BPEA was found in lung, brain, and liver tissues but distributed less efficiently into the brain than the parent compound. These findings help assess the drug's psychotropic and toxic effects.

5-iodo-2-aminoindan (5-IAI), a psychoactive derivative of 2-aminoindane, was identified in recreational products in the United Kingdom in 2011 after being anticipated by the EMCDDA in 2010. It is a rigid analogue of p-iodoamphetamine that produces MDMA-like effects. This paper summarizes the clinical, pharmacological, and toxicological information about this potential new drug of abuse.

Bromo-dragonfly, a potent and long-acting hallucinogen linked to severe vasoconstriction and fatal intoxications, was not metabolized in human liver microsomes, cytosol, or recombinant enzyme systems, unlike its analogue 2C-B-fly, which underwent monohydroxylation and N-acetylation via CYP2D6 and MAO-A. Bromo-dragonfly competitively inhibited monoamine oxidase A (MAO-A) with a Ki of 0.352 μM, and its IC50 suggested clinically relevant MAO-A inhibition, though further data are needed to assess its impact on serotonin levels in the body. Protein binding and pharmacokinetic parameters were also investigated.

Repeated ketamine exposure in neonatal rats reduces levels of DISC1 and several signaling proteins (pGSK-3β, β-catenin, pERK, pCREB, PSD95), leading to neuroapoptosis, inhibited neurite growth, and cognitive deficits in adolescence. Lithium treatment upregulates DISC1 and activates the GSK-3β/β-catenin and ERK/CREB pathways, thereby ameliorating these harmful effects. The findings suggest lithium may protect against ketamine-induced long-term neurotoxicity during brain development.
