A binuclear chloride bridged copper(II) complex with a modified ligand structure and different coordination environment and mononuclear cobalt(II) complexes with a pyridylpyrazole ligand: Synthesis, structure and cytotoxic activity

Coordination compounds of biogenic metals as cytotoxic agents in cancer therapy

The review summarizes the data on the structures and methods for the synthesis of compounds with anticancer activity based on biogenic metals, which can replace platinum drugs prevailing in cytotoxic therapy. The main focus is given to the comparison of the mechanisms of the cytotoxic action of these complexes, their efficacy and prospects of their use in clinical practice. This is the first systematic review of cytotoxic zinc, iron, cobalt and copper compounds. The structure – activity relationships and the mechanisms of antitumour action are formulated for each type of metal complexes.

(Acetato-κO){bis-[(2,4-dimethyl-1H-pyrazol-1-yl)meth-yl][(pyridin-2-yl)meth-yl]amine}-cobalt(II) hexa-fluorido-phosphate

In the title compound, [Co(CH₃CO₂)(C₁₈H₂₄N₆)]PF₆, the Co^II atom is penta­coordinated in a distorted trigonal–bipyramidal geometry by four N atoms from a tripodal ligand and one O atom from a monodentate acetate ligand. The crystal packing is stabilized by inter­molecular C—H⋯F and C—H⋯O hydrogen bonds.
