Dimethylidynemerocyaninocyanines ? substituted benzimidazole derivatives

Chemistry of Heterocyclic Compounds, 1984
Dimethylidynemerocyaninocyanines — substituted benzimidazole derivatives — were synthesized. A decrease in the basicity of the benzimidazole ring with intensification of the electronegative properties of the substituent gives rise to a small (up to 10 nm) heightening of the color of the dyes obtained.

Research on benzimidazole derivatives

Chemistry of Heterocyclic Compounds, 1974
The acylation of 2-amino-l-methylbenzimidazole in acetone proceeds with the formation of 2-amino-3-acyl-l-methylbenzimidazolium salts. When these salts are heated, they rearrange to 2-acylamino derivatives, but they react with bases to give 2-imino-3-acyl-l-methylbenzimidazolines, which are also readily rearranged to 2-acylamino derivatives.

Studies of benzimidazole derivatives

Chemistry of Heterocyclic Compounds, 1972
It was found that the formation of 2,5′- and 2, 6′-azobenzimidazoles, formed during the action of nitrosyl sulfuric acid on 2-amino-2-alkyl (phenyl, benzyl) benzimidazoles, occurs by azo combination of the extremely active salt of benzimidazole-2-diazonium obtained at first with the original amine.

Photophysical processes of some benzimidazole derivatives

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005
The photophysical properties of N-(alpha-naphthyl)-benzimidazole (alpha-NABI), N-(beta-naphthyl)-benzimidazole (beta-NABI) and N-(alpha-pyridyl)-benzimidazole (alpha-PYBI) were studied and alpha-NYBI exhibit intramolecular charge transfer fluorescence in polar solvents. The fluorescence of benzimidazoles can be quenched by acetic acid and the existence

[Pharmacokinetics of benzimidazole derivatives].

Voprosy meditsinskoi khimii, 2002
Pharmacokinetic properties of benzimidazole derivatives drug possessing antipsychotic, actoprotector, antiarrhythmic, antiulcerogenic, antiallergic, uricosuric, anthelmintic activities have been summarized. Pharmacokinetics of benzimidazole derivatives used in veterinary practice as anthelmintic drugs is also considered.

Antimicrobial Potential of Benzimidazole Derived Molecules

Mini-Reviews in Medicinal Chemistry, 2019
Structural resemblance of benzimidazole nucleus with purine nucleus in nucleotides makes benzimidazole derivatives attractive ligands to interact with biopolymers of a living system. The most prominent benzimidazole compound in nature is N-ribosyldimethylbenzimidazole, which serves as an axial ligand for cobalt in vitamin B12.

Benzimidazole Derivatives as Potential Anticancer Agents

Mini-Reviews in Medicinal Chemistry, 2013
Benzimidazole ring system is found in many bioactive heterocyclic compounds because of their diverse biological and clinical applications. Furthermore, benzimidazole derivatives are structural isosters of naturally occurring nucleotides, thus they can interact with biological macromolecules such as proteins, enzymes and receptors. This review discusses
