Four new Ni(II) complexes [Ni2(Msal-tsc)2(μ-dppm)] (1), [Ni2(Msal-mtsc)2(μ-dppm)] (2), [Ni2(Msal-etsc)2(μ-dppm)] (3) and [Ni2(Msal-ptsc)2(μ-dppm)] (4) containing 3-methoxy-salicylaldehyde-4(N)-substituted thiosemicarbazones having the general formula [H2-MSal-tsc-R],(where R = H, Me, Et or Ph) and 1,1′-bis(diphenylphosphino)methane (dppm) were synthesized and characterized by various spectral, analytical
摘要四种新的Ni(II)络合物[Ni2(Msal-tsc)2(μ-dppm)](1),[Ni2(Msal-mtsc)2(μ-dppm)](2),[Ni2(Msal-etsc) )2(μ-dppm)](3)和[Ni2(Msal-ptsc)2(μ-dppm)](4)含有具有通式[H2-合成了MSal-tsc-R](其中R = H,Me,Et或Ph)和1,1'-双(二苯基膦基)甲烷(dppm),并通过各种光谱,分析技术和X射线晶体学对其进行了表征。配合物1和3的晶体学研究揭示了镍离子周围的正方形平面几何形状。络合物与CT-DNA的结合能力是通过吸收/发射滴定来实现的,并且观察到结合的嵌入模式。此外,已经探索了它们与BSA蛋白相互作用的能力。对抗氧化性能的研究表明,所有化合物均具有很强的自由基清除性能。此外,还研究了化合物对肺癌细胞系A549的抗癌活性。从结果中可以观察到,配合物(2(IC50 =
