A new Cu(II)-based coordination polymer: crystal structure and protective effect on cardiac arrest induced by anesthesia via inducing SIRT1 signaling pathway. Issue 1 (2nd January 2021) - Liu, Minwei
Abstract: Based on a mixed-ligand strategy, a new coordination polymer with the chemical formula of [Cu(L)(1, 4-NDC)]n has been successfully synthesized by the reaction of L = 3, 6-bis(benzimidazol-1-yl)pyridazine (L) and Cu(NO3 )2 ·3H2 O with the presence of H2 NDC = naphthalene-1, 4-dicarboxylic acid as the co-ligand under the solvothermal methods. Furthermore, a green hand grinding technique has been implemented to reduce the particle size of the complex 1 to generate nanoscale 1 (denoted as nano 1 hereafter) with spherical morphology. Furthermore, the protective activity of nano 1 on cardiac arrest induced by anesthesia was evaluated in vivo . Firstly, after the construction of the cardiac arrest mice model and compound construction, the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) was measured to evaluate the cardiac functions. Then, the sirt 1 and nf-κb genes expression level was detected by reverse transcription-polymerase chain reaction (RT-PCR) assay.
