Biological Evaluation, Molecular Docking, and SAR Studies of Novel 2-(2,4-Dihydroxyphenyl)-1H- Benzimidazole Analogues
In the present study, new 4-(1H-benzimidazol-2-yl)-benzene-1,3-diols, modified in both rings, have been synthesized and their efficacies as acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors have been determined. The modified Ellman's spectrophotometric method was applied for the biological evaluation. The compounds showed strong (IC₅₀ 80-90 nM) AChE and moderate (IC₅₀ 5-0.2 µM)

One-step synthesis of novel biologically active 4- or 6-(4-methylidene-4H-3,1-benzothiazin-2yl)benzene-1,3-diols is described. The target compounds were prepared by the reaction of aryl-modified sulfinylbis[(2,4-dihydroxyphenyl)methanethione]s with 1-(2-aminophenyl)ethanones. Newly synthesized compounds were characterized by IR, 1H NMR, and mass spectral data. Their antiproliferative potency against human
Synthesis, characterization, and pharmacological evaluation of novel azolo- and azinothiazinones containing 2,4-dihydroxyphenyl substituent as anticancer agents
ABSTRACT: We reported the synthesis and characterization of a series of azolo- and azino[1,3]thiazinones containing the 2,4-dihydroxyphenyl substituent. The compounds were prepared by a new one-step reaction of aryl-modified sulfinylbis[(2,4-dihydroxyphenyl)methanethione]s and the corresponding aminoazolo(azino)carboxamides. Their chemical structures were confirmed by IR, NMR: 1H, 13C, HSQC, and EI-MS
