I · Summary

What is known

Published passages, each quoted whole and attributed to the database that published it. Two blocks are written here rather than quoted, and both say so where they stand: the synthesized summary at the top, which may draw only on the passages beneath it, and the history note, which cites the works it came from. Every claim in either carries a marker to its source.

What it is

  • 2-(4-iodo-2,5-dimethoxyphenyl)-1-methylethylamine is an organoiodine compound that is amphetamine bearing two methoxy substituents at positions 2 and 5 as well as an iodo substituent at position 4. It is a member of amphetamines, an organoiodine compound and a dimethoxybenzene. It is functionally related to an amphetamine.

    ChEBI

  • RN given refers to unlabeled parent cpd without isomeric designation; a serotonin agonist

    Medical Subject Headings (MeSH)

History, discovery and cultural use

— Not in this archive. PubChem, ChEMBL and the Human Protein Atlas publish pharmacology, regulation and toxicology, and none of them publishes a heading for when DOI was first made, by whom, or how it has been used. That is a gap in the databases this site reads and not a gap in the literature — the history of these compounds is written, at length and under peer review, in the works below. This site does not summarize them; it says where they are. Where a published passage above happens to touch origin or traditional use, it appears inside the entry that carries it.

Histories of this field

Scholarship on psychedelics generally, not on DOI specifically. Whether any of these treats this compound is a question for the book, not for this page.

Institutional archives

  • Heffter Research Institute Funds and coordinates clinical research on psilocybin, and keeps records of the studies it has supported since 1993. Sponsors the research it archives.
  • Multidisciplinary Association for Psychedelic Studies (MAPS) Sponsors clinical research, chiefly on MDMA-assisted therapy, and publishes an archive of historical and contemporary documents. A sponsor and an advocacy organization, not a disinterested archive; its clinical programme has a commercial arm.

The rest of this dossier

  • Affinity — 79 measurements in this archive, equilibrium constants kept apart from functional readouts.
  • Toxicology — nothing published for DOI. An absent record is an absence of study, not evidence of safety.
  • Legal — listed by the DEA among its drugs of concern, with no schedule stated in the record held here.
  • Systems — where this compound’s targets are transcribed, by brain region and tissue.

Passages via PubChem descriptive sections, aggregating DrugBank, LiverTox, FDA, DEA, HSDB, EPA. Each is quoted whole and attributed to the database that published it. The only prose written here about DOI is the history note, which says so on its face and carries a reference for every claim in it.

III · Behavior

Behavioral summary

Class, mechanism, and the duration of acute effects — each quoted from the record or trial that publishes it. Duration of effects and plasma half-life are shown separately, because they are different quantities and diverge by a factor of three or four.

Classification

Duration of acute subjective effects

—

No controlled human trial reporting a duration for this compound is cited here. The archive does hold onset and duration ranges for it, inherited from an earlier build, but their source column is empty and so they cannot be shown. A duration is not inferred from a chemical relative.

Plasma elimination half-life

How fast the body clears the drug — not how long the effects last. The two diverge sharply: LSD is cleared with a half-life of about 2.6 h while its subjective effects run 8–12 h.

No half-life is published for this compound in the sources this site reads.

Primary pharmacological drivers

ChEMBL holds no curated mechanism-of-action record for this compound. The measured affinities below are the evidence this archive has for what it binds.

IV · Clinical

Clinical description

Where this compound's substance class sits in ICD-11 and DSM-5-TR, and how much of the recorded literature speaks to each domain of a mental status examination.

Filed under Hallucinogens

  • 6C49Disorders due to use of hallucinogens

Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR): Hallucinogen-Related Disorders. Category names only — the manual is in copyright and no diagnostic criterion is reproduced here.

How much has been written about each domain

The clinical domains, and how many of the records this archive holds for this compound say something under each. What the terms mean, and the word list behind every spoke, are set out in the method.

None of the 0 records this archive holds for this compound uses a term from any of the clinical domains. That is a statement about the literature recorded here, not about the compound.

V · Systems

Each row joins two published measurements and nothing else: the affinity this archive holds for the compound at that target, and the transcript level the Human Protein Atlas reports for that target’s gene in that region. Bars scale with expression only. Expression is not activation — a receptor transcribed in a region is a receptor available to be bound there, which is a weaker and more defensible claim than saying the region is affected.

3 of this compound’s targets could not be resolved to a gene and are absent from both columns: 5-HT2, 5-HT5B, Serotonin (5-HT) receptor.

Fig. Radius is pX = −log₁₀(value in M), that is 9 − log₁₀(value in nM), computed from the normalized measurement. Hatched wedges are equilibrium binding constants (Ki, Kd); dashed outlines are functional readouts (IC₅₀, EC₅₀, AC₅₀, potency), which answer a different question and are not pooled with them. Rings mark whole pX units from 5 to 10, labeled every second ring in the gutter at the top. Where a target carries several measurements, the strongest is drawn.

VII · Toxicology

Toxicological profile

What has been measured, and what has been published — kept apart, and neither scored. There is no risk rating on this page; the archive once carried one, identical for every compound, produced by a stub.

Measured in this archive

Assays that bear on toxicity, drawn from the same ChEMBL records as everything else on this page. They are measurements of what a compound binds or does to cells — not verdicts about what it does to a person.

No hERG, cytochrome, cytotoxicity or transport measurement exists for DOI in this archive.

Published toxicology

— None. The toxicology databases this site reads — HSDB, RTECS and LiverTox, by way of PubChem — hold no record for DOI. They index compounds that have been studied for decades, so most of this archive has no entry. An absent record is an absence of study, not evidence of safety.

Published passages via PubChem toxicology sections, aggregating Hazardous Substances Data Bank (HSDB), RTECS, LiverTox. No figure on this page is scored, ranked or combined into a risk level.

IX · Trials

Registered clinical trials

Studies filed with ClinicalTrials.gov that name this compound as an intervention. A registered trial is a protocol, not a result — status and enrollment are printed beside every row, and withdrawn studies are counted rather than hidden.

— No registered study names DOI as an intervention. That is an absence of registered research, not evidence about the compound. Most of this archive has never been the subject of a registered trial.

Records from ClinicalTrials.gov (U.S. National Library of Medicine, NIH), API v2. A study is listed against a compound only when a verified name for that compound appears as a whole word in one of the study's own intervention names. A short code must appear as written, and a name the registry uses for something else (Aleph, a vaccine maker) is not matched. Title matches are not accepted. The matched name and the intervention text it matched are shown with every row.

Searched as 2,5-Dimethoxy-4-iodoamphetamine · 4-Iodo-2,5-dimethoxyamphetamine. Run this search at the registry.

A registered trial is a protocol somebody filed with the registry. It is not a result, and nothing on this plate says whether DOI worked.

XI · Literature

Sources behind this dossier

The papers this compound's values were read from, ranked by what each contributed. Not a review of the field.

Every paper below is one some value on this page came from — a binding constant, a passage of pharmacology or toxicology, or a measured duration. Each entry says what this archive took from it. Nothing else is claimed about any of them: the title is the study’s own account of itself, and a summary written here would be an assertion with no source behind it.
