  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.

• One-Pot Synthesis of Five and Six Membered N, O, S-Heterocycles Using a Ditribromide Reagent

  In a one-pot procedure, bromine less brominating reagent 1,1′-(ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) has been utilized as an efficient desulfurizing agent for the construction of a library of heterocycles containing N, O, and S starting from aryl/alkyl isothiocyanates. In this approach, aryl/alkyl isothiocyanate reacts with o-phenylenediamine (o-PD), o-aminophenol, and o-aminothiophenol

  在一锅法中，无溴溴化试剂1,1'-（乙烷-1,2-二基）二吡啶并溴化铋（EDPBT）已被用作有效的脱硫剂，用于构建含N，O的杂环文库和S从芳基/烷基异硫氰酸酯开始。在这种方法中，芳基/异硫氰酸烷基酯与邻苯二胺（o -PD），邻氨基苯酚和邻-氨基苯硫酚形成其单硫脲，用EDPBT脱硫分别形成相应的2-氨基苯并咪唑，2-氨基苯并恶唑和2-氨基苯并噻唑。对于一侧具有萘基部分而另一侧具有邻氨基或邻羟基苯基基团的不对称硫脲，观察到有趣的区域选择性，其产物完全不同，这主要取决于亲核试剂的性质（-OH或- NH 2）。此外，由脂族1,2-二胺与2当量的芳基异硫氰酸酯经EDPBT处理得到的双-硫脲得到了咪唑啉基碳硫代酰胺，而双-芳族1,2-二胺生成的-硫脲生成苯并咪唑并同时排出异硫氰酸酯单元。该方法是简单的，并且适用于各种适合溴化的底物，该底物显示出EDPBT的脱硫能力高于其溴化能力。最后，用过的试剂EDP

  A simple and novel method for the synthesis of N-aryl-2-aminobenzoxazoles from substituted benzoxazole-2-thiol and 2-chloro-N-arylacetamides in KOH-DMF system has been developed. The present protocol provides an attractive approach to access various N-aryl-2-aminobenzoxazoles in moderate to good yields without using transition metal catalyst under very mild reaction condition.
