Silver(I) complexes with 2,6-diacetylpyridine- bis (benzoylhydrazones): Antifungal activity and interaction with DNA

Some Aromatic Schiff Bases and Their Metal Complexes

“…The coordination geometry of this compound is also distorted like that in Sb(III) complex. Compounds of Ag(I) with the previous DAP-BHs, which express promising antifungal activity, were prepared and investigated also [99]. The pentadentate DAP-BH type Schiff bases can coordinate with lanthanides, such as Gd(III), Tb(III), Dy(III), and Er(III), too, and give stable single molecule-and single chain magnets [100][101][102], which keep their magnetism even after removal of the external magnetic field.…”

Pyridine Derivatives as Biologically Active Precursors; Organics and Selected Coordination Complexes

“…The activity of complexes was greater than respective pure ligands and the AgNO 3 salt. [108] A polynuclear complex of Ag ion with py-2-sulfonate 191 was studied as DNA binder, Topo-I inhibitor and as anticancer agent. [109] The polymeric complex was able to efficiently interact with DNA through minor intercalation, groove binding and its inhibitory effect was very much effective at 30 μM.…”

TEMPO coordination and reactivity in group 6; pseudo-pentagonal planar (η2-TEMPO)2CrX (X = Cl, TEMPO)

“…14 Note that these PPP complexes are unique, as all previous conformationally locked examples were of Ag + , a metal lacking the potential for ligand field stabilization. [15][16][17][18] The d-orbital splitting diagrams of (Z 2 -O,N-TEMPO) 2 CrX (X = Cl, 1; TEMPO, 2) are illustrated in Fig. 4, and are most easily understood by assigning the z-axis perpendicular to the core-atom plane.…”

“…During this study, examples of pseudo-pentagonal planar (PPP) coordination were discovered and are reported herein. Previously only observed in conformationally restricted chelate complexes, 15–18 the solid state, 19 and main group species, 20–23 they are rare additions to the lexicon of transition metal coordination environments.…”
