The compound crystallizes as dark-green prisms in space group P21/c of the monoclinic system, with Z=4 and unit cell dimensions a=1.710 9(7) nm, b=2.395 2(11) nm, c=1.348 9(6) nm and β=110.651(8)°. The complex consists of two similar but crystallographically independent dimers, of which Cu(Ⅱ) centers display five-coordinated trigonal-bipyramidal geometry with Cu-Cu separations in two centrosymmetric dimers are 0.345 1 and 0.347 8 nm, respectively, and in each dimer the two copper centers share a common edge formed by two bridging chloride ions, each being equatorial. Solvent molecules of CH2Cl2 are packed together in the crystal lattice. CCDC: 253299.展开更多
文摘目的探讨人胰岛素样生长因子(human insulin-like growth factor,hIGF-1)基因对软骨细胞分泌聚集蛋白多糖(aggrecan)、Ⅱ型胶原的影响.方法构建并鉴定携带hIGF-1基因的重组腺病毒(Ad/CMV-hIGF-1),采用1、10、100及500感染复数单位(multiplicity of infection,MOI)的Ad/CMV-hIGF-1转染软骨细胞,PBS为阴性对照,100μg/L hIGF-1生长因子为阳性对照,转染后4 d进行aggrecan、Ⅱ型胶原免疫组化,参照文献分析免疫组化阳性单位.结果在1～100MOI范围内,随着Ad/CMV-hIGF-1滴度增加,aggercan、Ⅱ型胶原表达递增,500 MOI Ad/CMV-hIGF-1转染后,aggrecan表达骤减;Ⅱ型胶原表达下降不明显.结论 hIGF-1基因对软骨细胞aggrecan、Ⅱ型胶原的表达有影响;100 MOI Ad/CMV-hIGF-1优于100 μg/L hIGF-1生长因子的作用.
