Synthesis, molecular docking, and inhibitory activity of a Ni Schiff-base complex against urease

A Ni(II) Schiff-base complex, Ni(C14H10NOBr2)2, was synthesized and structurally characterized by single-crystal X-ray analysis. Its inhibitory activity against Helicobacter pylori urease was evaluated in vitro and showed strong inhibitory activity against H. pylori urease compared with acetohydroxamic acid (IC50 = 42.12 mu mol L-1), which is a positive reference. A docking analysis using the autodock 4.0 program could explain the inhibitory activity of the complex against urease.
