The binding of amsacrine [4′-(9-acridinylamino)methanesulfon- m-anisidide] to calf thymus DNA was studied by UV-visible and resonance Raman spectroscopy. A shift of the UV-visible absorption band of amsacrine at 434 to 442 nm together with a decrease in the intensity of this band is observed upon amsacrine-DNA binding. The resonance Raman spectrum of DNA-bound amsacrine shows a general slight decrease in intensity relative to the spectrum of the free species. The significant decrease in intensity of the bands at 1165, 1265, and 1380 cm−1 upon binding to DNA is attributed to the formation of a single amsacrine-DNA species. The assignment of these bands (1165, 1265, and 1380 cm−1), which was based upon a previous normal coordinate analysis (NCA) and molecular neglect of diatomic overlap (MNDO) calculation, and the observed lack of shift in the band positions upon binding are consistent with intercalation being the major binding mode of amsacrine, as inferred previously by other techniques.

A new series of heterocyclic Schiff bases were prepared from condensation of 1-phenyl-3-methyl-4-acetyl/benzoyl-pyrazolone with 4,4′-diaminodiphenylmethane and 4,4′-diaminodiphenyl ether, resulting in the formation of four novel Schiff base ligands. These ligands were then treated with ethanolic solution of PdCl2, to form corresponding palladium(II) complexes. These complexes were characterized by elemental analysis, IR, 1H NMR, TGA, magnetic susceptibility measurements and UV-visible absorption spectroscopy. All the Pd(II) complexes were found to have one coordinated water molecule. Schiff base ligands chelated with the metal atom through two donor sites N and O of azomethine (-C=N-) and phenolic (-OH) groups, respectively.

Schiff Base Metal Complexes

A novel Schiff base [SAL-L=2-((2,3-dihydro-1H-inden-4-ylimino)methyl phenol] was synthesized and used as ligand for the synthesis of Ni(II) and Co(II) complexes. The structural characterization of ligand and its Ni(II) and Co(II) complexes was determined using various spectroscopic methods. Based on spectral studies, a square planar and octahedral geometry have been proposed for Ni(II) and Co(II) complexes, respectively. DNA binding properties of these metal complexes with calf-thymus DNA in tris-hydrochloride buffer (pH 7.2) were investigated using UV- visible absorption studies. The binding constants were in the order of 105 M-1 suggested a good binding affinity towards CT-DNA. The synthesized ligand is docked on TSPO protein showing good binding energy and found to be a potent inhibitor of cancer.
