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.
A 2011 publication [13] [J. Org. Chem., 2011, 76(23), 9577-9583] from a South Korean team outlined a novel, one-pot synthesis for substituted and unsubstituted 2-benzyl-benzimidazoles that can be easily adapted to the preparation of etonitazene.
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 5-acetyl analogue (Etoacetazene, 5-acetyldesnitroetonitazene) 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 ...
Based on the statements and interviews that have been made public so far, the news of Luigi Mangione’s arrest seems to have come as a shock to those who knew him.
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 It is an analogue of etonitazene where the 5-nitro (NO 2) group has been replaced by a nitrile (C≡N) group.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]
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 ...
