Abstract: A bis-Schiff base N,N'-bis(3,5-difluorosalicylidene)-1,3-diaminopropane) (H2L) was prepared. Reaction of H2L and manganese acetate with ammonium thiocyanate or sodium azide in methanol gave complexes[MnL(NCS)(OH2)] (1) and[MnL(μ1,3-N3)]n (2), respectively. H2L and the complexes were characterized by elemental analysis, IR spectra, 1H NMR spectra, and the crystal structures of the complexes were analyzed by single crystal X-ray diffraction. The Schiff base ligand coordinates to the Mn atom through the imino nitrogen and phenolate oxygen. The thiocyanate ligand coordinates to the Mn atom through the nitrogen atom, and the azide ligand coordinates to the Mn atom, with a bridging mode, through two terminal nitrogen atoms. In both complexes, the Mn atoms adopt octahedral coordination. The Schiff base and the complexes were tested for their Jack bean urease inhibitory activities. For complex 1, the inhibition rate at concentration of 100 μmol·L-1 on the urease is (52.0±3.1)%, and the IC50 value is (81.0±3.7) μmol·L-1. While for complex 2, it has no activity against the urease. Molecular docking study of complex 1 was performed to study the inhibition. |
