Microbial Assay of Ruthenium(II) Thiosemicarbazone Complexes: Synthesis, Spectral Characterization, and Electrochemistry
摘要:
Ruthenium complexes are synthesized with Schiff bases derived from salicylaldehyde/o-hydroxyacetophenone/o-vanillin/2-hydroxy-1-naphthaldehyde with thiosemicarbazide and thiophenecarboxaldehyde. Ruthenium coordinates in a tetradendate manner with these N2O2 donor ligands, which are characterized by elemental analysis, IR, electronic, and (HNMR)-H-1, C-13 NMR spectral studies. The elemental analysis suggests the stoichiometry to be 1:1 (metal: ligand). The redox behavior of the complexes has been investigated by cyclic voltammetric technique in the potential range -2.0 to +2.0 V. All the complexes were screened for their antimicrobial activity against two bacteria and two fungi. Further, two of these complexes were tested for its binding with CT-DNA using absorption studies.
