effective than the reference drug. 4‐(6‐Chloro‐4H‐3,1‐benzothiazin‐2‐yl)‐6‐methylbenzene‐1,3‐diol (5b) due to its very good activity (MIC from 1.56 to 3.13 µg/mL) and low cytotoxicity (IC50 > 50 µg/mL) may be regarded as a promising precursor for the development of novelantibacterial agents.
为了寻找一类新的抗菌剂,一系列苯并噻唑、1,3-噻唑并[5,4-b]吡啶、4H-3,1-苯并噻嗪、萘并[2,3-d][1、 3]制备了含有 2,4-二羟基苯基部分的噻唑-4,9-二酮和其他相关化合物。它们是通过芳基修饰的亚磺酰基[双(2,4-二羟基苯基甲硫酮)]与适当的商业化学试剂在内环化过程中反应获得的。通过两倍系列微量稀释肉汤方法评估化合物对八种参考细菌菌株的 MIC 值。它们对革兰氏阳性菌株表现出抑制作用,与革兰氏阴性菌株相反。一些化合物比参考药物更有效。4-(6-Chloro-4H-3,1-benzothiazin-2-yl)-6-methylbenzo-1,
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

analyses. The antiproliferative properties of some of the products againsthumancancercelllines were comparable to those of cisplatin. Structureactivity analysis showed that the presence of hydrophobic substituents in both heterocyclic fused and phenyl rings of the compounds improves their biological effects. Further, an additional OH group in the resorcinol moiety reduced the antiproliferative activity
已经描述了新的 4-(1,3-噻唑并[5,4-b]吡啶-2-基)苯-1,3-二醇的一锅法合成。这些化合物是通过亚磺酰基双[(2,4-二羟基苯基)甲硫酮]衍生物与2-氯吡啶-3-胺反应制备的,芳环上有各种取代基。它们的结构是从 IR 和 1H-和 13C-NMR 光谱、质谱和元素分析推导出来的。一些产品对人类癌细胞系的抗增殖特性与顺铂相当。结构活性分析表明,化合物的稠合杂环和苯环中疏水取代基的存在提高了它们的生物学效应。此外,间苯二酚部分中的额外 OH 基团降低了抗增殖活性。
