Manganese(II) complex of 6,7-dicycanodipyridoquinoxaline with antitumor activities: synthesis, crystal structure and binding with DNA

Mn(II) complexes with sulfonamides as ligands.

“…The Mn-N bond distances are essentially identical and close to those reported for other Mn compounds; a similar comment can be made for the Mn-O distances from the solvent molecules directly coordinated to the Mn(II) cations [40,41]. The N1-Mn-N2 and N3-Mn-N4 bond angles are also very similar to each other for all five complexes, close to 73°, while the angles formed between Mn and N atoms from different ligand molecules are larger than 90°.…”

Three new Cu(II) and Cd(II) complexes with 3-(2-pyridyl)pyrazole-based ligand: Syntheses, crystal structures, and evaluations for bioactivities

“…where t is the°C ratio of the bound compound to DNA base pairs, c is the free complex concentration, K b is the intrinsic binding constant and n is the binding site size [37,38].…”

Synthesis, characterization, DNA binding properties and antioxidant activity of a manganese(II) complex with NO6 chromophore

“…Furthermore, high intracellular Mn(II) concentrations could provide protection against oxidative stress [7][8][9][10] and Mn(II) could act as an antioxidant backup for the CuZn-SOD [11]. However, reports of biologically relevant manganese complexes are limited [12][13][14][15][16][17][18][19][20][21][22], while a relatively small number of Mn(II) complexes were used for DNA interaction and nuclease activity studies [13][14][15][16][17][18][19][20][21]. The most active SOD mimetic known to date are seven coordinate macrocyclic Mn(II) complexes (Mn(II)( [15]aneN 5 ) type) [23 and rfns therein], while manganese complexes with acyclic multidentate ligands are still very limited [24][25][26][27][28][29][30].…”
