Spectroscopic and biological activity studies on tridentate Schiff base ligands and their transition metal complexes

“…The lipid membrane surrounding the cell favours the passage of only lipid soluble materials; thus the lipophilicity is an important factor that controls the antimicrobial activity. Also the increase in lipophilicity enhances the penetration of Schiff base and its metal complexes into the lipid membranes and thus restricts further growth of the organism [41,42]. This could be explained by the charge transfer interaction between the studied molecules and the lipopolysaccharide molecules which lead to the loss of permeability barrier activity of the membrane.…”

Synthesis, characterization, spectroscopic and crystallographic investigation of Cobalt(III) schiff base complex with two perpendicular diamine coumarin ligands

“…[18,19]. They are also increasingly important as biochemical, analytical and antimicrobial reagents [20]. Further, significant advances have also been achieved in the field of straightforward preparation of new chiral ligands, such as chiral diamines and complexes, used for asymmetric catalysis [21].…”

Syntheses, Crystal Structures and Thermal Behaviors of Two Supramolecular Salamo-Type Cobalt(II) and Zinc(II) Complexes

“…Disappearance of the band is expected for the metal complexes as a result of the substitution reaction when the OH hydrogen is substituted or replaced by the metal ions, thus leading to the complex formation [60].…”

“…Meanwhile, on account of the fact that the high electronegative oxygen atoms affect azomethine nitrogen and N 2 O 2 coordination plane on the basis of Salamo-type bisoxime ligands [45,[51][52][53][54][55], many complexes exhibit abundant interests, attractive structures and properties have been well documented [56][57][58][59]. Furthermore, metal ions play key roles in wide range of differing biological processes and the interaction of the metal ion with drugs employed for therapeutic reasons is a subject of considerable interest [60]. Herein, following our previous studies on the syntheses, structural characterizations and optical properties of Salamo-type complexes with the d 5 …”
