Urease inhibition studies of six Ni(II), Co(II) and Cu(II) complexes with two sexidentate N2O4-donor bis-Schiff base ligands: An experimental and DFT computational study. J Inorg Biochem. 2019 Dec 16;204:110959 Authors: Wang H, Xu C, Zhang X, Zhang D, Jin F, Fan Y Abstract Six novel complexes, [Ni(C36H34N2O10)]·2.25CH3OH·0.5C4H10O (1), [Co(C36H34N2O10)] (2), [Cu(C36H34N2O10)]·2CH3OH (3), [Ni(C36H32N2O8Cl2)]·2CH3OH (4), [Co(C36H32N2O8Cl2)]·4CH3OH (5) and [Cu(C36H32N2O8Cl2)]·2CH3OH (6) with two sexidentate N2O4-donor bis-Schiff base ligands (C36H34N2O10 = 1,2-bis(2-methoxy-6-formylphenoxy)ethane-l-tyrosine; C36H32N2O8Cl2 = 1,2-bis(2-methoxy-6-formylphenoxy)ethane-l-4-chlorophenylalanine) have been synthesized and structurally characterized. Theoretical calculation of the six complexes was carried out by density functional theory (DFT) Becke's three-parameter hybrid (B3LYP) method employing the 6-3lG basis set, indicating that the calculation results are in accordance with experimental results. Moreover, the inhibitory activities of complexes 1-6 were tested in vitro against jack bean urease. At the same time, molecular docking was investigated to determine the probable binding mode. The experimental values and docking simulation exhibited that complexes 3 and 6 showed strong inhibitory activity (IC50 = 10.36 ± 1.13, 15.63 ± 3.04 μM) compared wi...
