Antibacterial Properties of New Chitosan-Based Schiff Bases.

Synthesis, Structure and Biological Activity Studies of New Metal Ion Complexes Based on 3-[(3-Hydroxynaphthalene-2-yl-ethylidene)-hydrazono]-1,3-dihydro-indol-2-one

“…This corresponds to the magnetic moment of the hexagonal complexes found inside the octahedron (C.T, 4 T 1 g (F) → 4 A 2 g (F) , 4 T 1 g (F) → 4 T2g (F) and 4 T 1 g (F) → 4 T 2 g (F) ). The Ni(II) complex's electronic spectrum had four peaks at 445, 478, 627, and 935 nm, which represent four transitions (C.T, 3 A 2 g (F) → 3 T 1 g (P) , 3 A 2 g (F) → 3 T 2 g (F) and 3 A 2 g (F) → 3 T 2 g (F) ), respectively [22]. The complex magnetic moment value of Ni(II) was 3.05 B.M., confirming its high spin octahedral geometry.…”

“…Hydrazine derivatives are often employed in various biological activities. Many hydrazones have been employed as antimicrobial medications, which are commonly used to treat a variety of biological functions [3]. The enormous biological importance of Schiff bases-benzohydrazide derivatives has urged us to synthesize Schiff bases derivatives from benzohydrazide with functionalization of amino group with heterocyclic compounds with anti-inflammatory selective inhibitor, anti-fungal, antibacterial, and antiinflammatory activities [4][5][6].…”

Synthesis, Characterization and Biological Activity Study for Some New Metals Complexes with (3Z,3'E)-3,3'-(((2E,5E)-hexane-2,5-diylidene)bis(hydrazine-2,1-diylidene))bis(indolin-2-one)

“…Schiff bases are organic compounds originating from the condensation of a primary amine with an aldehyd e or a keton, to give imine_groups. Electronic and steric effects can be easily adjusted by the proper choice of the amine and substituted carbonyl compound, to provide Schiff bases with great structural variability [1,2]. Schiff bases constitute an important class of ligands with wide application in coordination chemistry: these bases can serve as bis-, tris-, tetra-, penta-or polydentate ligands for transition and representative metals and ions.…”
