RESUMO
By employment of a rigid tripodal nitrogen-containing heterotopic ligand tris(1-imidazolyl) benzene (Htib), a new fluorescent Zn(II)-containing coordination polymer {[Zn(tib)2](NO3)2(H2O)3}n (1) with a rare two-fold interpenetrating (3,6)-connected pyr network topology has been successfully prepared under the solvothermal reaction conditions. Under the condition of visible light irradiation, rhodamine B (RhB) and methylene blue (MB) could be degraded with good performance. In the biological function study, the cytotoxicity of the synthetic was evaluated with CCK-8 detection kit on human umbilical vein endothelial cells (HUVEC). The inhibitory effect of compound on vcam-1 expression in the vascular endothelial cells was evaluated by RT-PCR. The effect of the complex on the inflammatory response in the vascular endothelial cells was determined via ELISA test of IL-1ß and TNF-α. The results of pose scoring software as well as molecular docking was conducted to explore the interaction between compounds and VCAM, which might provide latent regulatory mechanisms along with binding sites for compounds.
