Etonitazene, also known as EA-4941 or CS-4640, [2] is a benzimidazole opioid, first reported in 1957, [3] that has been shown to have approximately 1,000 to 1,500 times the potency of morphine in animals.
Corresponding analogues where the N,N-diethyl group is replaced by piperidine or pyrrolidine rings also retain significant activity (10 times and 20 times morphine, respectively). [2] Etodesnitazene has been sold as a designer drug , [ 3 ] first being identified in both Poland and Finland in March 2020.
Flunitazene (Fluonitazene) is a benzimidazole derivative with opioid effects, first developed in the 1950s as part of the research that led to better-known compounds such as etonitazene.
Methylenedioxynitazene (3',4'-Methylenedioxynitazene) is a benzimidazole derivative which has been sold as a designer drug over the internet and presumably has opioid effects. It is an analogue of etonitazene where the benzyl ring is substituted with a 3,4-methylenedioxy ring system rather than an ethoxy group. It was first reported in the UK ...
Etonitazene 5-cyano analogue (Etocyanazene, 5-cyanodesnitroetonitazene) is a benzimidazole derivative with opioid effects, first developed in the 1950s as part of the research that led to better-known compounds such as etonitazene. It is an analogue of etonitazene where the 5-nitro (NO 2) group has been replaced by a nitrile (C≡N) group. [1]
Butonitazene is a benzimidazole derivative with opioid effects, which has been sold over the internet as a designer drug.It has relatively low potency compared to many related compounds, and has generally been encountered as a component of mixtures with other substances rather than in its pure form.
Benzimidazole is a base: C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] + It can also be deprotonated with stronger bases: C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry. The most prominent benzimidazole complex features N-ribosyl-dimethylbenzimidazole, as ...
