A Cu(II)-based coordination polymer: catalytic properties and treatment activity on stroke
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.
期刊介绍:
Designed Monomers and Polymers ( DMP) publishes prompt peer-reviewed papers and short topical reviews on all areas of macromolecular design and applications. Emphasis is placed on the preparations of new monomers, including characterization and applications. Experiments should be presented in sufficient detail (including specific observations, precautionary notes, use of new materials, techniques, and their possible problems) that they could be reproduced by any researcher wishing to repeat the work.
The journal also includes macromolecular design of polymeric materials (such as polymeric biomaterials, biomedical polymers, etc.) with medical applications.
DMP provides an interface between organic and polymer chemistries and aims to bridge the gap between monomer synthesis and the design of new polymers. Submssions are invited in the areas including, but not limited to:
-macromolecular science, initiators, macroinitiators for macromolecular design
-kinetics, mechanism and modelling aspects of polymerization
-new methods of synthesis of known monomers
-new monomers (must show evidence for polymerization, e.g. polycondensation, sequential combination, oxidative coupling, radiation, plasma polymerization)
-functional prepolymers of various architectures such as hyperbranched polymers, telechelic polymers, macromonomers, or dendrimers
-new polymeric materials with biomedical applications
