Synthesis, Characterization, Hydrolytic Cleavage, and Biological Activity Studies of 2-[(1e)-N-{2-[(2-{(Z)-[1-(2-Hydroxyphenyl)Ethylidene] Amino}Ethyl)Amino]Ethyl}Ethanimidoyl]Phenol

摘要

A Schiff base ligand 2-[(1 E )- N -{2-[(2-{( Z )-[1-(2-hydroxyphenyl) ethylidene] amino}ethyl)amino]ethyl} ethanimidoyl]phenol L was hydrolyzed by copper cation which lead to formation of 8,8-dichloro-2H,3H,5H,6H-1,3-diaza-2-cupracyclopenta[1,3-a]1,3-diaza-2-cupracyclopentane hydrate (Complex), characterized by UV, IR, Powder XRD and by elemental analysis. In vitro antioxidant and anticoagulant, activities of L were evaluated. Antioxidant potential of L was assessed by DPPH scavenging, β-carotene bleaching test, hydroxyl radical scavenging method, ABTS radical scavenging test, and by reducing power test. In vitro anticoagulant effect of L at the 84 μg/mL; showed the maximum prolongation of plasma recalcification time which is comparable with that of the anticoagulant drug; heparin. In conclusion, results of the present investigation indicate that the ligand L can be a potential anticoagulant agent. Keywords : Schiff base; Antioxidant; Free radicals; Anticoagulant.
