    Click Chemistry Approach for Bis-Chromenyl Triazole Hybrids and Their Antitubercular Activity
    摘要:
    1,4‐Disubstituted bis‐chromenyl triazole hybrids 5am have been synthesized in a three‐step reaction sequence from 4‐(bromomethyl)‐2H‐chromen‐2‐ones 3am. The intermediate azides 4am underwent a regioselective 1,3‐dipolar cycloaddition with a 2H‐chromen‐2‐one linked acetylenic dipolarophile in the presence of Cu (II)/ascorbate/water/n‐butanol reaction medium. Three compounds 5hj exhibited 6.25 μg/mL MIC against M. tuberculosis. Among the compounds screened for antifungal activity, lowest MIC of 6.25 μg/mL was observed for 5c against A. niger that also exhibited DNA cleavage observed by agarose gel electrophoresis. All the compounds were moderately active against both Gram‐positive and Gram‐negative bacterial strains. The cytotoxic effect of potent compounds on normal cells (V79 and HBL100) was assessed by MTT assay.

    新型香豆素-肟醚的合成和评价作为潜在的抗结核药:其DNA裂解能力和BSA相互作用研究
    摘要:
    为了开发具有治疗意义的新型香豆素-肟醚共轭物,使用溴甲基香豆素与丁烷-2,3-二酮一肟的S N 2反应合成了一系列香豆素-肟醚(1a-1j)。针对香豆素-肟醚(1a – 1j)建立了针对MTBH 37 Rv菌株的体外抗结核活性。大多数化合物在0.04–3.12μgmL -1的最小抑菌浓度(MIC)下表现出显着的活性。化合物(1h)被鉴定为MIC值为0.04μgmL -1的命中候选物。,接近于异烟肼的MIC值(0.02μgmL -1),这是一种用于治疗肺结核的市售药物。化合物1h在Vero细胞中也表现出低水平的毒性和良好的体外安全性。还发现显示出有效的抗结核活性的化合物能更有效地裂解DNA,从而表现出核酸酶活性。进一步研究了活性最高的化合物(1h),以推论与模型血清蛋白牛血清白蛋白(BSA)的相互作用方式。

    Background: Tuberculosis is one of the top ranked airborne infectious diseases caused by the bacillus Mycobacterium tuberculosis with high mortality rate from a single infectious agent. In the present article, we aimed to synthesize oxadiazole-coumarin-triazole based small molecules and evaluate for their possible anti-mycobacterial activity. Method: Herein, we describe the facile synthesis of 5-((1H-benzo[d][1,2,3]triazol-1-yl)methyl)-1,3,4- oxadiazole-2-thiol-tethered substituted 4-(bromomethyl)-7-methyl-2H-chromen-2-one derivatives and evaluated for their anti-mycobacterial activity against H37Rv strain of M. tuberculosis. We also evaluated the cytotoxic effect of new compounds on normal cells. Results: Among the 14 novel oxadiazole-coumarin-triazole derivatives, 4-((5-((1H-benzo[d][1,2,3]triazol-1- yl)methyl)-1,3,4-oxadiazol-2-ylthio)methyl)-6-methoxy-2H-chromen-2-one (5f) displayed good antimycobacterial activity towards M. tuberculosis with an MIC value of 15.5 µM. Pyrazinamide was used as reference drug. Our investigation also revealed that, 5f is not cytotoxic to normal cells. Conclusion: In summary, the findings suggested that novel 1,3,4-oxadiazole coumarin-triazole hybrids are promising antimycobacterial agents against M. tuberculosis.
    背景:结核病是由结核分枝杆菌引起的高度致死性空气传播传染病之一。在本文中,我们的目标是合成基于噁二唑-香豆素-三唑的小分子并评估它们可能的抗结核活性。 方法:在此,我们描述了5-((1H-苯并[d][1,2,3]三唑-1-基)甲基)-1,3,4-噁二唑-2-硫醇缀合的取代4-(溴甲基)-7-甲基-2H-色烯-2-酮衍生物的简易合成,并评估了它们对M. tuberculosis H37Rv菌株的抗结核活性。我们还评估了新化合物对正常细胞的细胞毒性效应。 结果:在14种新型噁二唑-香豆素-三唑衍生物中,4-((5-((1H-苯并[d][1,2,3]三唑-1-基)甲基)-1,3,4-噁二唑-2-基硫)甲基)-6-甲氧基-2H-色烯-2-酮(5f)显示出对M. tuberculosis的良好抗菌活性,MIC值为15.5 µM。利福平被用作参考药物。我们的研究还揭示,5f对正常细胞没有细胞毒性。 结论:总之,研究结果表明,新型1,3,4-噁二唑香豆素-三唑杂化物是针对M. tuberculosis有前景的抗结核药物。
