Synthesis, characterization, crystal structure and antibacterial activity studies of cobalt(II) and zinc(II) complexes containing halogen quinoline Schiff base ligand

Synthesis, Characterization, and Antioxidant Activities of Schiff Base and Fe(II) Complex

“…Transition metal complexes with nitrogen, sulphur or oxygen as ligand atoms became increasingly important because these Schiff bases can bind to different metal centres with different coordination sites, allowing the successful synthesis of metal complexes with interesting stereochemistry [1,2]. In addition, sulphur-and nitrogen-containing ligands and their transition metal complexes have been used as corrosion inhibitors [3,4], as extreme pressure lubricant additives [5], and have shown broad biological activity [6][7][8][9][10] due to the different ways in which they bind to metal ions. They can be bidentate, tridentate, tetradentate or polydentate.…”

“…Schiff-base transition metal complexes play an important role in developing coordination chemistry for magnetic, catalytic and enzymatic processes, molecular structures and optical materials. These complexes can also exhibit biological activity as anti-fungal, anti-bacterial, anti-malarial, anti-tumour, anti-proliferative, anti-inflammatory, anti-viral and antioxidant agents [2][3][4].…”

“…As for the chemical coordination of iron with this type of Schiff base ligands, the growing interest for the new synthesized complexes is preferred due to the presence of this element in several biological systems [3][4][5][6][7]. Iron complexes exhibit numerous interesting biological activities including as antibacterial, antimicrobial, antifungal, antioxidant, antitumor activity, and anticancer.…”

Co (II), Ni (II), and Cu (II) complexes of 4,6‐bis(2‐hydroxynaphthalen‐1‐yl)methyl‐ene)hydrazono)ethyl)benzene‐1,3‐diol: Synthesis, spectroscopic, biological, and theoretical studies

“…[44][45][46] The Co, Ni, and Cu complexes have an interesting role in bioinorganic chemistry such as antibacterial, antifungal, anticancer, DNA cleavage, antioxidant, and DNA binding activities. [47][48][49][50][51][52][53][54][55][56][57][58][59][60] Furthermore, copper (II) complexes have several advantages as effective anticancer agents. These advantages include (i) their strong DNA binding capability and (ii) the highly selective permeability of Cu (II) ions through the cell membrane of cancer cells.…”

NiIIand CoIIbinary and ternary complexes of 3-formylchromone: spectroscopic characterization, antimicrobial activities, docking and modeling studies

“…Nickel and cobalt elements are generally required for life as nickel is involved in a variety of enzymes 13 and cobalt in vitamin B-12 and a number of therapeutics. 14 Their complexes have different biological applications; 15–19 some are used as cisplatin alternatives in cancer treatment 20 and some as catalysts in the oxygenation processes of organic molecules. 21…”
