The 2-methylpyridine, 2-diethylaminoethyl, and isopentyl linked a series of symmetric and unsymmetric benzimidazolium salts 2a-e were prepared and used in the synthesis of silver-N-heterocyclic carbene (NHC) complexes (3a-e). The Ru(II)-NHC complexes (4a-h) were synthesized via transmetalation reaction from 3a-e. 4a-h complexes were converted to Ru(II)-NHC.HCl complexes (5ah) by HCl solution of diethyl ether and characterized by different spectroscopic techniques such as 1H and 13C NMR, LC/MS-Q-TOF, FT-IR, elemental analysis, and melting point detection. We examined the effect of the structural difference of complexes on anticancer activity via different arenes and metal centers. Antiproliferative activity of 5a-h and 3a was tested against human cervix adenocarcinoma (HeLa) and rat glioblastoma (C6) cell lines by ELISA assay. The IC50 value of 5b, 5c and 5e complexes exhibited good cytotoxic activity than cisplatin on C6 (14.2 ± 0.5 mM; 16.2 ± 0.4 mM; 24.2 ± 0.7 mM, respectively) and HeLa (11.1 ± 0.5 mM; 13.7 ± 0.3 mM; 22.8 ± 0.8 mM, respectively) cell lines.
2-甲基吡啶、2-二乙基氨基乙基和异戊基连接了一系列对称和非对称的苯并咪唑鎓盐2a-e,用于合成银-N-杂环卡宾(NHC)络合物(3a-e)。通过3a-e的转金属反应,合成了Ru(II)-NHC络合物(4a-h)。4a-h络合物通过二乙醚的HCl溶液转化为Ru(II)-NHC.HCl络合物(5ah),并通过1H和13C NMR、LC/MS-Q-TOF、FT-IR、元素分析和熔点检测等不同的光谱技术进行表征。我们研究了不同芳烃和金属中心的络合物结构差异对抗癌活性的影响。通过ELISA测定,对5a-h和3a的抗增殖活性进行了测试,分别针对人宫颈癌腺癌(HeLa)和大
