“…However, sometimes the reaction proceeds to a further step, and the cyclization of the formed diimine compound results in benzimidazole compounds. Many benzimidazole derivative compounds synthesized in this manner have been reported in the literature [1][2][3][4][5][6][7][8]. Sometimes a catalyst is used in the synthesis of benzimidazole compounds [1,[4][5][6].…”

Ion sensor properties of 4-(1-(4-hydroxy-3-methoxybenzyl)-1H-benzo [d]imidazol-2-yl)-2-methoxyphenol (L) in acetonitrilewater (1 : 1) were evaluated by fluorescence spectrometry. Pronounced quenching in the fluorescence spectra of the ligand was only observed for the Cu 2+ ion among many metal ions. Linear fluorescence responses of the ligand at 360 nm as the function of the Cu 2+ concentration were used for the determination of the Cu 2+ ion in spiked tap water samples. Recovery values (R%) were satisfactory, and relative standard deviation (RSD%) was below 5.00 in intraday and interday measurements. Detection and quantification limits were 0.28 and 0.84 μg/L, respectively. e assay based on external calibration only took a few minutes. Experimental2.1. Chemicals and Apparatus. For synthesis, o-phenylenediamine, p-vanillin, and methanol were obtained from Merck and used directly. Spectrometric-grade acetonitrile as

“…Thiophene and its derivatives have been widely distributed in many naturally occurring compounds and are employed to address different health hazards. They are responsible for various biological activities such as anti-inflammatory [ 2 ], antipyretic [ 3 ], anti-hypotensive [ 4 ], anti-convulsant [ 5 ], anti-viral [ 6 ], antitumor [ 7 ], fungicidal [ 8 ], herbicidal [ 9 ], anti-microbial [ 10 ] activities, and act as a plant-growth regulator [ 11 ]. Some of the thiophene derivatives exhibited divergences in anti-diabetic and anti-inflammatory activities [ 12 ].…”

A novel fused system with three or four fused rings—pyridazino[3′,4′:5,6][1,2,4]triazino[4,3-b][1,2,4,5]tetrazine and pyridazino[3′,4′:5,6][1,2,4]triazino[3,4-b]pyrimido[4,5-e][1,3,4]thiadiazine was obtained from the starting materials 4(6H)-amino-3-hydrazino-7-(2-thienyl)pyridazino[3,4-e][1,2,4]-triazine 2 and 9-amino-3-(2-thienyl)-2H,8H-pyridazino[3′,4′:5,6][1,2,4]triazino[3,4-b][1,3,4]thiadiazine-8-carbonitrile 12. Each of the starting compounds was subjected to a number of cyclization reactions to obtain a series of new heterocyclic fused systems, 3–10 and 13–23, via bifunctional reagents. Some of the synthesized compounds were screened against three cell lines including HepG2, HCT-116 and MCF-7 to discover their anticancer activity. The synthesized compounds were characterized depending on their elemental analyses and spectral data.
