Two new Cd(II) coordination polymers: Luminescent properties and protective activity on ischemic myocardial infarction

Two new compounds based on Cd(II) ion as metal nodes, that is, [Cd (pam) (3-bpmh) (DMF)]n (1) and [Cd2(Hbci)2 (3-bpmh)2]n·nH2O (2) (3-bpmh is N,N-bis-pyridin-3-ylmethylene-hydrazine, H3bci ​= ​bis(2-carboxyethyl)isocyanurate, and H2pam ​= ​pamoic acid), were successfully prepared via a dual-ligand strategy under solvothermal conditions. Furthermore, the luminescent performances and thermal stabilities of the prepared compounds were explored. During myocardial infarction, there were characteristic changes of the patients' electrocardiograms. For the treatment of ischemic myocardial infarction, the adenosine 5′-monophosphate-activated protein kinase inflammatory signaling pathway was determined through applying real-time reverse transcription-polymerase chain reaction after conducting the indicated treatment. Next, the enzyme-linked immunosorbent assay was implemented, and the levels of inflammatory cytokines during ischemic myocardial infarction were determined.
