Structures with names 4- and 5-nitroimidazole are equivalent from the perspective of drugs since these tautomers readily interconvert. Drugs of the 5-nitro variety include metronidazole, tinidazole, nimorazole, dimetridazole, pretomanid, ornidazole, megazol, and azanidazole. Drugs based on 2-nitroimidazoles include benznidazole and azomycin. [3]
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.
5-Nitro-DMT (5-nitro-N,N-dimethyltryptamine) is a substituted tryptamine derivative which acts as a serotonin receptor agonist, [1] though its subtype selectivity has ...
The metabolism of topically applied nitrofurazone is thought to be by 5-nitro reduction and cleavage of the -CH=N- linkage to generate a reactive species which can covalently bond to cellular macromolecules, none of the end products are thought to be antimicrobial. [1] [14]
Acetic acid [2-[(5-nitro-2-thiazolyl)amino]-oxomethyl]phenyl ester is a carboxylic ester and a member of benzamides. It is functionally related to a salicylamide. Nitazoxanide [25] is the prototype member of the thiazolides, which is a drug class of structurally-related broad-spectrum antiparasitic compounds. Nitazoxanide belongs to the class ...
The 2-Halo-5-nitro-phenylamine requires a bromo or iodo group for optimal activity. 2-Chloro-phenylamines are completely unreactive. In addition to these three components, the reaction was optimized in the presence of 0.05 molar equivalents (5 mol%) of a catalyst, copper(I) chloride, and 5 mol% of ligand, TMEDA (tetramethylethylenediamine).
Nitrofurans are a class of drugs typically used as antibiotics or antimicrobials. [1] The defining structural component is a furan ring with a nitro group. [2] Drugs
Metonitazene is an analgesic compound related to etonitazene, [2] [3] which was first reported in 1957, [4] and has been shown to have approximately 1000 times the potency of morphine by central routes of administration, [5] but if used orally it has been shown to have approximately 10 times the potency of morphine.
