In the title mononuclear Cd(II) complex, [CdCl(2)(C(11)H(17)N(3))], the Cd(II) atom is coordinated by two Cl atoms and three N atoms from the tridentate Schiff base ligand in a distorted square-pyramidal environment. The three N atoms and one Cl atom constitute the base of the pyramid, whereas the other Cl atom occupies the apical position.

The efficient asymmetric synthesis of unnatural alkenyl amino acids required for peptide 'stapling' has been achieved using alkylation of a fluorine-modified Ni(II) Schiff base complex as the key step.

A novel copper(II) complex of quinolin-4(3H)-one derived Schiff base ligand was synthesized and characterized by elemental analyses, IR, 1H-NMR, MS, UV–Vis, magnetic moments, conductance measurements and thermal studies. The DNA binding and nuclease activities of copper(II) complex was performed. key words: Copper(II) complex; spectral studies; DNA interaction studies. received: February 02, 20...

Little is known about the molecular mechanism of Schiff base hydrolysis in rhodopsin. We report here our investigation into this process focusing on the role of amino acids involved in a hydrogen bond network around the retinal Schiff base. We find conservative mutations in this network (T94I, E113Q, S186A, E181Q, Y192F, and Y268F) increase the activation energy (E(a)) and abolish the concave A...
