Zn(II)-Based Coordination Polymer for Detection of Picric Acid in Aqueous Media and Treatment Effect against Deep Vein Thrombosis by Reducing P-ERK2 and p53 Expression.

The coordination polymers based on Zn(II) ions and the metal nodes which has chemical formula of {[Zn3(L)2(tib)2(H2O)2]·(DMF)2}n (1) was synthesized via using 1,3,5-tris(1-imidazolyl)benzene (tib) and 2,6-di(4-carboxylphenyl)pyridine-4-carboxylic acid (H3L) as ligands under solvothermal conditions. Given its strong luminescent emission at room temperature and the uncoordinated N-donor sites in the framework, the selective detection performance of 1 toward the nitroanalytes was studied, 1's sensitive fluorescence quenching reactions along with selectivity to the electron-deficient TNP over other analytes of nitro within the aqueous phase was studied via the method of fluorescence quenching titration. Furthermore, the treatment effect of the compound on the deep vein thrombosis (DVT) was evaluated. Firstly, the ELISA was carried out to determine IL-17A content. Then, the platelet function was determined via the western blot by measuring expression level of platelet activation signaling pathway protein p-ERK2 and p53.
