Abstract

In this study, novel peripherally 4-[(1H-benzimidazol-1-yl)methoxy] substituted Zn(II) (3) Cu(II) (4) and Co(II) (5) phthalocyanines were prepared and their structures were characterized spectroscopically. The light absorption behaviors of the synthesized compounds (3-5) were studied by UV-Vis spectroscopy at different concentrations in different solvents. The urease inhibition activities of the synthesized compounds were also investigated. Among the synthesized molecules, compound 4 showed the best inhibitory effect against jack bean urease with IC50 values of 0.0036 +/- 0.0010 mu M. (C) 2019 Elsevier B.V. All rights reserved.
