25I-NBOMe (or 2C-I-NBOMe ) is a research chemical with hallucinogenic and psychedelic effects, which, due to its structure, belongs to the groups of phenol ethers and phenethylamines . The effect is attributed, among other things, to the properties of the 25I-NBOMes as a potent agonist on the serotonin receptor 5-HT 2A . 25I-NBOMe is a derivative of 2C-I .
history
25I-NBOMe was developed in 2003 by Ralf Heim at the Free University of Berlin as part of his doctoral thesis "Synthesis and pharmacology of potent 5-HT 2A receptor agonists with N-2-methoxybenzyl partial structure" . The 11 C -labeled compound ([ 11 C] Cimbi-5) of 25I-NBOMe was synthesized at the University of Copenhagen and validated as a radiotracer for positron emission tomography (PET).
Pharmacodynamics
25I-NBOMe binds to the individual receptors with the following K i values:
receptor | K i (nM) | ± |
---|---|---|
5-HT 2A | 0.044 | |
5-HT 2C | 2 | |
5-HT 6 | 73 | 12 |
µ-opioid | 82 | 14th |
H 1 | 189 | 35 |
5-HT 2B | 231 | 73 |
k-opioid | 288 | 50 |
Legal status
- Germany
- 25I-NBOMe was recommended on May 6, 2013 at the 40th meeting of the Narcotics Expert Committee of the Federal Institute for Drugs and Medical Devices for inclusion in Annex I to Section 1 (1) BtMG. An actual admission took place with the 28th ordinance amending the narcotics regulations on December 6, 2014. Like the related 25B-NBoMe, it has been subject to the Narcotics Act (Germany) since then and its possession and trade are therefore illegal.
- European Union
- On September 25th, 2014 the EU banned 25I-NBOMe, MDPV , AH-7921 and methoxetamine . The manufacture and sale of the substance is therefore prohibited. The EU states had a year to implement the ban.
