  Synthesis, biological evaluation and molecular docking study of N -arylbenzo[ d ]oxazol-2-amines as potential α-glucosidase inhibitors

  摘要：

  A novel series of N-arylbenzo[d]oxazol-2-amines (4a-4m) were synthesized and evaluated for their alpha-glucosidase inhibitory activity. Compounds 4f-4i, 4k and 4m displayed potent inhibitory activity against alpha-glucosidase with IC50 values in the range of 32.49 +/- 0.17-120.24 +/- 0.51 mu M as compared to the standard drug acarbose. Among all tested compounds, compound 4g having 4-phenoxy substitution at the phenyl ring was found to be the most active inhibitor of ot-glucosidase with an IC50 value of 32.49 +/- 0.17 mu M. Analysis of the kinetics of enzyme inhibition indicated that compound 4g is a noncompetitive inhibitor of alpha-glucosidase with a K-i value of 31.33 mu M. Binding interaction of compound 4g with alpha-glucosidase was explored by molecular docking simulation. (C) 2016 Elsevier Ltd. All rights reserved.

  The desulfurization ability of diacetoxyiodobenzene (DIB) has been explored in the preparation of isothiocyanates from the corresponding dithiocarbamate salts. The in situ generated isothiocyanates reacted with o-phenylenediamine and o-aminophenol to form monothioureas, which, on treatment with a further equivalent of DIB in one pot, gave benzimidazoles and aminobenzoxazoles, respectively. Aliphatic

  二乙酰氧基碘苯 (DIB) 的脱硫能力已在从相应的二硫代氨基甲酸盐制备异硫氰酸酯中进行了探索。原位生成的异硫氰酸酯与邻苯二胺和邻氨基苯酚反应形成单硫脲，在一锅中用另外等量的 DIB 处理，分别得到苯并咪唑和氨基苯并恶唑。脂肪族 1,2-二胺与 2 当量反应。异硫氰酸酯，然后用 DIB 处理得到咪唑烷亚碳硫酰胺，而芳香族 1,2-二胺双（硫脲）的处理得到苯并咪唑，同时形成异硫氰酸酯。后者形成的驱动力是产品的芳构化。DIB 的使用使这些方法更简单、更高效，
