The complexes were characterized by elemental analysis, XRD, UV, IR and 1H NMR. The crystal structure of the complexes belongs to triclinic system with the cell parameters: a =1 297 1 nm, b =1 621 0 nm, c =2 047 0 nm, α =85 40°, β =88 80°, γ =99 00° for [CuC 30 H 26 N 2O 4·0 5H 2O]; a =1 300 2 nm, b =1 882 6 nm, c =2 127 4 nm, α =86 47°, β =89 23°, γ =99 11° for [NiC 30 H 26 N 2O 4]; a =1 286 5 nm, b =1 596 1 nm, c =2 056 9 nm, α =87 95°, β =93 17°, γ =98 21° for [CoC 30 H 26 N 2O 4], respectively. The N and O atoms in the complexes appeared coordinated directly to the metal ions. A quadridentate chelate may be formed.展开更多
文摘目的探讨褪黑素(melatonin,MT)改善二苯酮-3(benzophenone-3,BP-3)暴露小鼠卵母细胞质量的作用及机制。方法试验将6~12周龄的ICR雌鼠GV期卵母细胞分别在M16培养液、0.8μmol/L BP-3培养液以及1×10-7mol/L MT+0.8μmol/L BP-3混合培养液中进行体外培养。将ICR雌鼠随机分为3组:对照组、BP-3组、BMT组;对照组灌胃0.5 m L纯净水、BP-3组灌胃0.5 m L含0.8μmol/L BP-3的药物溶液、BMT组灌胃0.5 m L含0.8μmol/L BP-3以及15 mg/kg MT的药物溶液,每天1次,连续灌胃4周,进行体内实验。随后通过检测3组小鼠的MⅡ期卵子成熟率,线粒体动力学相关基因Mfn1、Opa1、Fis1、Drp1的转录水平及其蛋白表达水平,线粒体膜电位及纺锤体形态来探讨MT对BP-3暴露小鼠卵母细胞线粒体的挽救作用。结果与对照组相比,MT处理显著增加了BP-3组卵母细胞中线粒体融合基因Mfn1和Opa1的转录及蛋白水平表达,同时下调了线粒体分裂基因Fis1和Drp1的m RNA与蛋白表达。此外,BMT组的卵母细胞ROS水平和纺锤体形态异常比例明显低于BP-3组,但其线粒体膜电位显著升高。结论生理浓度BP-3暴露具有生殖毒性,但添加适当浓度的MT可以明显改善BP-3暴露小鼠卵母细胞的线粒体动力学及其发育潜能。
