Abstract:
<p>Schiff base ligands and their 3d-metal chelates have gained significant attention due to various applications in various scientific platforms. Due to their chelating propensity, they possess a wide range of biological, biochemical, catalytic, clinical, dying, and pharmacological properties.<strong> </strong>Here, in present studies,<strong> </strong>two novel Ni(II) and Zn(II) transition metal chelates have been synthesized by condensing their metal salts with Schiff base ligand 4-chloro-2-(2,5-dimethoxybenzylideneamino)-5-nitrophenol<strong> </strong&

Abstract:
Thrombin is a trypsin-like serine protease that plays a critical role in the blood coagulation cascade. Thus, studies on thrombin-specific inhibitor are useful for the design of clinical useful compounds. We have previously reported of the Schiff base metal chelates carrying benzamidine and amino acid moieties. More than 50 kinds of Schiff base copper(II) chelates were synthesized fromp- orm-amidinosalicylaldehyde and various L- or D-amino acids. These chelates have effective inhibitory activity for trypsin and thrombin (Ki= 10-5~ 10-6M). In this series of inhibitors, the copper(II) chelate de

La(III), Zr(IV), and Ce(IV) chelates of 2-[(4-[(Z)-1-(2-hydroxyphenyl)ethylidene]aminobutyl)-ethanimidoyl]phenol were synthesized and characterized by using several physical techniques. The Schiff base was obtained by refluxing of o-hydroxyacetophenone with 1,4-butanediamine in 2 : 1 molar ratio.
