In this report, we designed and synthesized a series of cobalt(II)-Schiff base complexes (CoSBC) with competent MEK1 (mitogen-activated protein kinase kinase?1) inhibitory activity. Based on our previous report, the CoSBC exhibited high binding affinity with MEK1 protein. To further explore metal complexes as MEK1 inhibitors, a series of transition metals and ligands were employed to build a library of various metal Schiff base complexes. The MEK inhibition assays revealed that only CoSBC exhibited obvious inhibitory activity, complex 2b showed the best inhibition both in BRaf (B-rapidly accelerated fibrosarcoma)/MEK1 and MEK1/ERK2 (extracellular signal-regulated kinases-2) cascading (IC50 is 1.988 ± 0.14 μM and 1.589 ± 0.054 μM respectively). In addition, homogeneous time-resolved fluorescence test method was used to prove that CoSBC as ATP-noncompetitive MEK1 inhibitor. MEK kinase selectivity assay indicated that CoSBC can selectively inhibit MEK1/2 kinases rather than other MAPKs (mitogen-activated protein kinases) family kinases. Moreover, the interaction mode of 2b with MEK1 protein has been demonstrated by computer aided drug design.

Electrochemical properties of a series of differently substituted vanadyl salen complexes were investigated using cyclic voltammetry in different solvents. Results obtained show that the salen structure stabilizes the oxidized forms and that the effects of substituents on the oxidation potential correlate with the electronic density of the metal. Also the role of the donicity of the solvent in influencing the redox potentials of the studied complexes has been evidenced. Moreover, the variations of the observed potentials can be qualitatively correlated to the catalytic activity of vanadyl salen derivatives in the oxidation of thioethers.
