Nitazene / Nitazine
This article says a related chemical which is yet to have its own article is called 'Nitazene' however the opioid template says that it is called 'Nitazine'. This may cause confusion when the chemical article is created. Nagelfar (talk) 17:24, 9 November 2008 (UTC)

Strongest?
US Patent 2,944,062 describes a derivative with an added amide moiety: CCOC1=CC=C(C=C1)C(C(N)=O)C2=NC3=C(C=CC(N(=O)=O)=C3)N2CCN(CC)CC

My German is very poor but as I understand it, etonitazine which they previously tested was 60x M (by the same team) while examples XIX (above) is x200. The original huge figures are typical of initial patents and such.

212. Benzimidazol-Derivate und verwandte Heterocyclen VI l) Synthese von Phenyl-[l-aminoalkyl-benzimidazolyl-(2)]-essigsaureestern und -amiden von A. Hunger, J. Kebrle, A. Rossi und K. Hoffmann (19. VIII. 60)

I am afraid I don't know how to change the images but I believe that this racemic derivative is over 3x the parent compound. The amide may be a bioisostere of the beta hydroxy seen in potent fentanyl derivatived, It overlays the ORL1 full-agonist MCOPPB so maybe, much like combined mu & delta agonism seems to vastly increase analgesic potency (see 14-methoxy metopon), dual mu & ORL1 ligands may be more potent. — Preceding unsigned comment added by 213.106.56.145 (talk) 11:24, 6 October 2013 (UTC)

I have added a patent which produces analogues x4 more potent. I'm no good a graphics, but if someone could take these into account. Most excitingly, I suspect that their increased nociception is due to it's ORL1 affinity (unknown in 1960). SMILES C1=C(N(=O)=O)C=CC2N(CCN(CC)CC)C([C@H](C(N)=O)C3=CC=C(OCC)C=C3)=NC1=2 — Preceding unsigned comment added by 213.106.56.145 (talk) 16:48, 6 October 2015 (UTC)

2 References deal with the (R) amide moiety on the methylene (-CH2-) spacer. The German studies list etonitazene as being 60x morphine, also given for human potency and the amide as having a potency of x200 morphine. While the patent doesn't deal with the chiral compound but the paper specifies the (R) isomer. This is important for the understanding of the QSAR. The initial potency was tested using the Straub tail test. This test is famously unreliable and the German studies used tail-withdrawal tests on a much bigger cohort of tests. While the NOP activity is a hypothesis, it does offer the possibility of developing new analgesics with a much larger ratio between analgesic and euphoric doses. — Preceding unsigned comment added by 81.99.74.135 (talk) 09:08, 15 November 2017 (UTC)

I don't read german but i can read tables and despite these multiple edits and talk on this article over multiple years i think this "4x stroger / 200x morphine in humans" amide derivative is incorrect and a misunderstanding (also incorrectly written on the article as carboxide, should be carboxamide). The papers are all released as a series by the same authors in the same year.

10.1002/hlca.19600430412 Lists compound XXXVIII (Etonitazene) as 1000x morphine potency

10.1002/hlca.19600430634 Lists compound XIX (Carboxamide derivative) as 200x morphine potency

Testing methods are listed below the tables and has the same reference. Unless it mentions somewhere those are human numbers why would we assume that one suddenly changes testing methods from rats to humans? Should that whole paragraph be removed as it may be based on a wrong understanding and speculation? LeviathanBaphomet (talk) 14:37, 21 February 2020 (UTC)

Deaths
I believe Thomas K Highsmith commited suicide and a batch made in Moscow killed a number of people. I cannot remember where I read it, but I think it's important to make people understand just how dangerous the stuff is. — Preceding unsigned comment added by 81.99.74.135 (talk) 12:42, 19 January 2017 (UTC)

Animal models
"It is, however, useful in animal models for addiction studies" - what does "animal models" mean? Are these some kind of artificial devices or a euphemism for vivisection? Perhaps we should call things by their real names - animals or animals in labs? Trendorder (talk) 15:08, 13 April 2024 (UTC)

Error in synthetic scheme
The scheme for the 2011 synthesis is wrong. One methylene group too many between the phenyl ring and the imidazole group. 219.74.165.120 (talk) 13:26, 11 June 2024 (UTC)
