Complexes of Co(II), Cu(II) and Ni(II) with Antineoplastic Agent Imatinib Mesylate: Synthesis, Characterization and Biological Activity
The aim of this work was to investigate the interaction of Imatinib mesylate with biological ions Cu(II), Co(II) and Ni(II) in ethanol/water solutions. Structures of synthesized complexes were characterized by spectroscopy methods. Stereo-microscopy was used for determination of morphological properties of obtained crystals. The results of IR spectroscopy showed that biogenic metal complexes with ImM were formed through the oxygen donors of mesylate ion. Changes of crystals colours and sizes of the parent ligand and complexes were clearly seen. Antimicrobial screening revealed a significant effect of Co(ImM)2 complex on the tested microorganisms. This complex also showed significant antioxidant activity compared to Ni(II) and Cu(II) complexes.
