2,5-Dimethoxy-4-iodamphetamine (abbreviated DOI ) is a research chemical which, due to its structure, belongs to the phenol ethers and substituted amphetamines . In neuroscience , DOI is used as a radioligand to research the 5-HT 2 serotonin receptors .
history
The American chemist Alexander Shulgin synthesized DOI for the first time and mentions synthesis, dose and effect in his book PiHKAL . Various radionuclides of iodine were incorporated into DOI, the [ 125 I] - R - (-) - DOI was first developed by the American pharmacologist David E. Nichols.
Pharmacological properties
Pharmacokinetics
Shulgin gives the orally effective threshold dose for psychedelic effects as 600 µg. For the full psychedelic effect, a dose of 1.5-3 mg is given. The duration of action is 16–30 hours.
effect
In high doses, DOI has a similar effect to LSD , which is based, among other things, on its effect as an agonist on the serotonin receptors 5-HT 2A / 2C ; however, the casting time is doubled. In cell experiments with doses below the psychedelic threshold dose, a strong anti-inflammatory effect was observed, with the DOI strongly inhibiting the tumor necrosis factor TNF-α over a longer period of time.
Legal status
In Germany, DOI is a marketable , but not a prescription drug, because it is listed in Appendix II BtMG .
