Abstract
An innovative heterocyclic biologically active chalcone 1,2,3-triazole analogs (6a–j) were prepared to extract excellent yields by coupling the substituted aryl azides (5a–5j) and 5-ethynyl-1,2,3-trimethoxybenzene, by using the method of Huisgen azide–alkyne cycloaddition. The typically synthesized analogs were elucidated by IR, 1H-nuclear magnetic resonance (NMR), 13C-NMR, and Electron spray ionization (ESI)-mass spectroscopy and tested for their cytotoxicity effectiveness in MTT assays against the A549 lung cancer cells. The cytotoxic studies suggested that a few analogs showed moderate to good activities. The compounds 6i and 6c showed low cytotoxicity against the A549 cell line among 12 analogs, the values of IC50 were displayed in the range of 65.05 ± 1.12 and 71.56 ± 1.29 µM, respectively. The compound 6j showed slightly less cytotoxicity but showed good selectivity against A549 cell lines.
摘要
通过将取代的芳基叠氮化物(5a-5j)和 5-乙炔基-1,2,3-三甲氧基苯偶联,采用 Huisgen 叠氮-炔环加成法制备了具有创新性杂环生物活性的查耳酮 1,2,3- 三唑类似物(6a-j),并获得了极高的产率。通过红外光谱、1H-核磁共振(NMR)、13C-NMR 和电子喷雾电离(ESI)-质谱对典型合成的类似物进行了阐释,并在 MTT 试验中测试了它们对 A549 肺癌细胞的细胞毒性。细胞毒性研究表明,一些类似物显示出中等至良好的活性。在 12 种类似物中,化合物 6i 和 6c 对 A549 细胞株的细胞毒性较低,IC50 值分别为 65.05 ± 1.12 µM 和 71.56 ± 1.29 µM。化合物 6j 的细胞毒性略低,但对 A549 细胞株具有良好的选择性。
