In this study, a new Cd(II)-bearing coordination polymer with the chemical formula of [Cd4(meda)3(dpe)4(H2O)4]·(NO3)2·2(H2O)}n (1, H2meda = 3,3′-methylenedibenzoic acid, dpe = 1,2-di(pyridin-4-yl)ethane) has been successfully prepared by reaction of Cd(NO3)·4H2O with a V-shape carboxyl ligand H2meda along with the linear dipyridine ligand dpe under the hydrothermal conditions. Due to its intensive luminescence, complex 1 could be utilized as the sensor of detecting Al3+ ion, and its detection limit is 4 × 10−6 M. Firstly, the toxicity of the compound on the normal liver cells was determined with Cell Counting Kit-8 detection kit. The triglyceride in liver cells was detected by detection kit after compound treatment and the relative expression of 15-lox and 12-lox in L02 cells was also measured by RT-PCR after compound treatment. In addition, multiple functional groups that provided by the synthesized Cd(II) complex have been studied by using molecular docking simulation for the confirmation of possible binding modes that formed between ligand and receptor.
本研究制备了一种新型含Cd(II)配位聚合物,其化学式为[Cd4(meda)3(dpe)4(H2O)4]·(NO3)2·2(H2O)}n (1, Cd(NO3)·4H2O与V型羧基配体H2meda反应,成功制备了H2meda = 3,3′-亚甲基二苯甲酸、dpe = 1,2-二(吡啶-4-基)乙烷)水热条件下线性二吡啶配体dpe。由于配合物1发光强度强,可以作为检测Al3+离子的传感器,其检测限为4 × 10−6 M。首先,使用细胞计数试剂盒测定该化合物对正常肝细胞的毒性- 8 检测试剂盒。化合物处理后采用检测试剂盒检测肝细胞中的甘油三酯,并采用RT-PCR测定化合物处理后L02细胞中15-lox和12-lox的相对表达量。此外,通过分子对接模拟研究了合成的Cd(II)配合物提供的多个官能团,以确认配体和受体之间可能形成的结合模式。
