Mixed-ligand copper complexes with unsymmetrical tridentate Schiff base ligands and 2,2′-bipyridine: Synthesis, x-ray crystallography and antibacterial properties

Synthesis and crystal structures of new mixed-ligand schiff base complexes containing N-donor heterocyclic co-ligands: Molecular docking and pharmacophore modeling studies on the main proteases of SARS-CoV-2 virus (COVID-19 disease)

“…The value of (τ) is almost between the two limiting values but it is slightly closer to that of SBP and hence, the geometry could be described as distorted SBP [ 22 ]. The obtained bond lengths, bond angles, and the (τ) value is in the same range of previously reported similar complexes [ [23] , [24] ]. The weak hydrogen bonds N-H…O, table 3 , together with the CH-π and π - π stacking interactions stabilize the entire 3D Network structure ( figure 3 ).…”

Synthesis of new Schiff bases; Investigation of their in situ catalytic activity for Suzuki CC coupling reactions and antioxidant activities

“…[31][32][33] In addition, Alimirzaei and coworkers examined copper complexes of Schiff-bases for antimicrobial activities against grampositive and gram-negative bacteria, and obtained relatively good results. 34 On the other hand, there are many reported studies, which showed effective antioxidant properties of Schiff bases in the literature. [35][36][37] In this paper, new Schiff base derivatives have been synthesized and all structures have been identified by using NMR, FTIR, and GC-MS techniques.…”

“…For example, Yilmaz and coworkers synthesized new palladium and ruthenium complexes of Schiff bases and these complexes showed important catalytic activity for Suzuki, Heck CC cross‐coupling reactions together with catalytic hydrogenation and transfer hydrogenation reactions 31–33 . In addition, Alimirzaei and coworkers examined copper complexes of Schiff‐bases for antimicrobial activities against gram‐positive and gram‐negative bacteria, and obtained relatively good results 34 . On the other hand, there are many reported studies, which showed effective antioxidant properties of Schiff bases in the literature 35–37 …”

Synthesis, Characterization, Antibacterial and Antifungal Activities Evaluation of Metal Complexes With Benzaldehyde‐4‐methylthiosemicarbazone Derivatives

“…[8] These properties make metal complexes good candidates with biological properties such as effective antimicrobial agents. [9] Specifically, transition metal complexes of thiosemicarbazone derivatives were extensively studied because of their numerous biological activities [10] against malarial, [11][12][13] bacterial, [14] fungal infections, [15][16][17] in addition to their antitumor activity against various cancer cell lines. [18][19][20][21][22][23] Substituted benzaldehyde N(4)-thiosemicarbazones with functional group attached at meta and para position on the aromatic ring and, an alkyl group at the terminal N4 nitrogen atom and the presence of a functional binding site, [6,24,18] made them the subjects of broad investigation because of their properties as herbicides, insecticides and plant growth regulators.…”
