A series of new triazole fused imidazo[2,1-b]thiazole hybrids (9a–u) were designed, synthesized and evaluated as antimicrobial agents. Compounds 9c, 9d, 9e, 9j and 9l showed promising broad spectrum antimicrobial activity. Further, compound 9c exhibited significant anti-biofilm activity with single and mixed biofilm disruption demonstrated by Field Emission Scanning Electron Microscope (FE-SEM). Furthermore
设计,合成并评估了一系列新型的三唑稠合的咪唑并[2,1- b ]噻唑杂化物(9a – u)。化合物9c,9d,9e,9j和9l显示出有希望的广谱抗菌活性。此外,通过场发射扫描电子显微镜(FE-SEM)证明,化合物9c具有明显的抗生物膜活性,并且具有单个和混合的生物膜破坏。此外,分子对接研究表明它们与毒力因子金黄色葡萄球菌相互作用。脱氢角鲨烯合酶(CrtM)(PDB ID:2ZCS)。总体而言,这些发现表明化合物9c是进一步开发新型抗菌和抗生物膜剂的潜在先导。

the synthesis of this new heterocyclic scaffold is an intramolecular cyclization via an unprecedented carbonylativeC–H functionalization of 1‐(2‐bromoaryl)‐1,2,3‐triazoles. Isotopic labelling of the carbonyl carbon atom is possible using near stoichiometric amounts of 13CO. Additionally, an alternative pathway via carbonylative Sonogashira coupling followed by a two‐step, one‐pot azidation/cycloaddition
这项研究提出了4 H- [1,2,3]三唑[1,5 - a ]吲哚-4-酮的合成。合成这种新型杂环骨架的关键步骤是通过空前的1-(2-溴芳基)-1,2,3-三唑的羰基化CH功能将分子内环化。可以使用接近化学计量的13 CO进行羰基碳原子的同位素标记。此外,还研究了通过羰基Sonogashira偶联然后进行两步单罐叠氮化/环加成反应的替代途径,从而产生了相同的骨架。
The construction of fully decorated 1,2,3-triazoles has been disclosed via a bimetallic relay-catalyzed cascade process combining azide–alkyne cycloaddition, C(sp2)–H functionalization of 1,2,3-triazoles and isocyanide insertion.
