A cu(Ii)-based coordination polymer: Treatment activity on tuberculosis by inhibiting the survival of the mycobacterium in alveolar macrophages

Abstract

Via utilizing the mixed-ligand method, a novel coordination polymer (CP) containing Cu(II) has been prepared by self-assembly at the ambient temperature, and its chemical formula is {[Cu(BINDI)0.5 (bpe)]·3H2O}n (1, bpe = 1,2-bis(4-pyridyl)ethylene and H4BINDI = N,N′-bis(5-isophthalic acid) naphthalenediimide). For the treatment of the tuberculosis, its biological function was evaluated as well. The CFU assay was performed to determine the bacterial numbers of the Mycobacterium in alveolar macrophages. In addition to this, the ropA gene of the Mycobacterium in alveolar macrophages was also detected through the real time RT-PCR method. Only the oxygen atoms on the metal complex are identified to be able to interact with the probe protein by molecular docking simulation.
