The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
Etodesnitazene (also known as desnitroetonitazene, etazen, etazene, and etazone) is a benzimidazole-derived opioid analgesic drug, which was originally developed in the late 1950s alongside etonitazene and a range of related derivatives. [1]
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.
Ethyleneoxynitazene (Tetrahydrofuranitazene) 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 4-ethoxy group attached to the benzyl ring has been cyclised round to the 3-position to form a 2,3-dihydrobenzofuran ring system.
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 ...

BOSTON – Two people were arrested Saturday night in Boston for what police describe as a "hazardous drone operation.". Robert Duffy, 42, of Charlestown, and 32-year-old Jeremy Folcik of ...
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.
