<i>Retracted</i> : Two Cu( <scp>II</scp> )?based coordination polymers: Treatment activity on diabetic nephropathy via reducing aldose reductase activity and blood glucose concentration

Two new Cu(II)-based coordination polymers, one of which is the {[Cu(?3-fdc)(?-dptztz)(H2O)]·DMF}n (1) and another {[Cu(?3-tdc)(?-dptztz)]·DMF}n (2) (fdc = 2,5-furandicarboxylate, dptztz 2,5-di(4-pyridyl)thiazolo[5,4-d]thiazole tdc 2,5-thiophenedicarboxylate,) were synthesized by Cu(NO3)2·3H2O reacting with different carboxylate ligands (H2fdc H2tdc for 1 2, respectively). Single-crystal X-ray diffraction, powder thermogravimetric analysis, also elemental analysis used to complete study compounds. Moreover, protective activity compounds on diabetic nephropathy was assessed. Firstly, aldose reductase measured, as well blood glucose concentration. Then, cell death glomerular vascular endothelial cells measured lactate dehydrogenase release (LDH) assay.
