  Synthesis, in vitro antioxidant, anthelmintic and molecular docking studies of novel dichloro substituted benzoxazole-triazolo-thione derivatives

  摘要：

  A novel 6,8-dichloro [1,2,4]triazolo [3,4-b] [1,3]benzoxazole-3(2H)-thione 4 and its derivatives 5a and 5b are synthesized from 5,7-dichloro-2-hydrazinyl-1,3-benzoxazole 3, obtained by reaction of hydrazine hydrate with ethyl [(5,7-dichloro-1,3-benzoxazol-2-yl)sulfanyl]acetate 2. The newly synthesized compounds are characterized by analytical (1)H NMR,(13)C NMR, LC-MS mass spectrometry and elemental analysis. All synthesized compounds are screened for in vitro antioxidant and anthelmintic activities. In correlation to anthelmintic activity, compounds are subjected to molecular docking studies for the binding to beta-Tubulin, target protein elite to the parasites.Compounds 3, 4 and Sa exhibited potential radical scavenging capacity with good anthelmintic activity. In molecular docking study also, compounds showed minimum binding energy and have good affinity toward the active pocket thus, they may be considered as good inhibitor of beta-Tubulin.

  N-methylbenzo[d]oxazol-2-amine (2a), which had comparable potency to albendazole, an orally administered anthelmintic drug, against Gnathostoma spinigerum, Caenorhabditis elegans and Trichinella spiralis. Compound 2a showed about 10 times lower cytotoxicity towards normal human cell line (HEK293) than albendazole. Moreover, we have developed new processes for the synthesis of N-alkylbenzo[d]oxazol-2-amine

  我们发现了一种先导化合物N - methylbenzo[ d ]oxazol-2-amine ( 2a )，它具有与阿苯达唑相当的效力，阿苯达唑是一种口服的驱虫 药，可以对抗棘口线虫、秀丽隐杆线虫和旋毛虫。化合物2a对正常人细胞系 (HEK293) 的细胞毒性比阿苯达唑低约 10 倍。此外，我们还开发了合成N-烷基苯并[ d ]恶唑-2-胺和N-烷基苯并[ d ]的新工艺] thiazol-2-amine 衍生物通过无金属条件。该协议可以作为一种稳健且可扩展的方法，特别是合成N-甲基苯并 [ d ]恶唑-2-胺和N-甲基苯并[ d ]噻唑-2-胺衍生物，这些衍生物难以使用其他无金属条件制备. 该方法使用苯并恶唑-2-硫醇或苯并噻唑-2-硫醇作为底物。该反应由硫醇官能团的甲基化引发，形成甲基硫化物中间体，这是一种关键策略，它促进了与N-甲基甲酰胺原位产生的气态甲胺的顺利亲核加成-消除反应。此
