A Cu(II)-based coordination polymer: catalytic properties and treatment activity on stroke
1Neurology Department, Xingyuan Hospital of Yulin, Yulin, Shaanxi, China.
Abstract:
A fresh Cu(II) coordination polymer, i.e., [Cu3(Hmbdc)2(mbdc)2(dmphen)2]n (1, H2mbdc = isophthalic acid, dmphen = 4,7-dimethyl-1,10-phenanthroline), has been generated with the hydrothermal reactions between Cu salts and the mixed ligands of 4,7-dimethyl-1,10-phenanthroline and isophthalic acid. Moreover, the catalytic activity of 1 was evaluated via degrading the Congo red with a method of Fenton with an excellent degradation efficiency of 95.8% at 100 min. Next, the application value of compound on stroke was assessed, and the related mechanisms were explored at the same time. First of all, the tumor necrosis factor-α and recombinant rat IL-1β content released into the plasma were determined with enzyme-linked immunosorbent assay detection kit. Besides, the activation of the HMGB1/TLR4 signaling pathway activation in cerebral vascular endothelial cells was also determined with real-time reverse transcription-polymerase chain reaction assay.

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
