Synthesis and Analgesic Activity of Novel Derivatives of 1,2-Substituted Benzimidazoles
Journal of Chemistry, 2013 A series of novel 2-phenylhydrazinomethyl and 2-(2-hydroxyphenyl)-benzimidazole derivatives substituted at the N1-position of benzimidazole nucleus were synthesized as well as screened for analgesic activity.

Synthesis, biological investigation, and docking studies of benzimidazole derivatives as butyrylcholinesterase and acetylcholinesterase inhibitors [PDF]
شیمی کاربردی روزThe cholinergic hypothesis is one of the hypotheses of Alzheimer's disease that shows the relationship between the onset and progression of the disease. One of the main ways to increase the level of acetylcholine is to inhibit cholinesterase enzymes. The

Benzimidazole derivatives endowed with potent antileishmanial activity [PDF]
Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 Two sets of benzimidazole derivatives were synthesised and tested in vitro for activity against promastigotes of Leishmania tropica and L. infantum. Most of the tested compounds resulted active against both Leishmania species, with IC50 values in the low micromolar/sub-micromolar range.

Trimerization of aromatic nitriles [PDF]
, 1977 Triazine compounds and cross-linked polymer compositions were made by heating aromatic nitriles to a temperature in the range of about 100 C to about 700 C, in the presence of a catalyst or mixture of catalysts.

Unexpected N-C bond fission of fused N-alkylbenzimidazolium salts. A new approach to pyrido[1,2-a]- or pyridazino[1,6-a]benzimidazoles [PDF]
, 1998 The reaction of N-carboxymethylpyrido[1,2-a]- and pyridazino[1,6-a]benzimidazolium salts with thionyl chloride resulted in an N-C bond fission, yielding the corresponding pyrido[1,2-a]- and pyridazino[1,6-a]benzimidazoles.

Angewandte Chemie, EarlyView.N‐alkylated heteroarenes are key structural motifs in bioactive compounds, but their regioselective synthesis via coupling of readily available azoles with haloalkanes remains very challenging. Here, we present a mild biocatalytic approach that proceeds on gram‐scale, is highly chemo‐ and regioselective, offering rapid access to valuable N‐alkylated ...

Advanced Materials Technologies, EarlyView.A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Angewandte Chemie, EarlyView.In loosely packed nanoaggregates, increased deuteration enhances photoluminescence quantum yields (PLQY) and extends the fluorescence lifetimes of tetraphenylethylene (TPE) by reducing internal conversion rates. Conversely, in tightly packed crystalline states, deuteration leads to decreased PLQY and shortened lifetimes, attributable to the Duschinsky ...
