There are many properties of metal ions that were useful for solving basic problems in medicine, metal complexes with particular properties can be covalently affected to biological macromolecules. Mono Co(II), Ni(II) ,Cu(II) ,Zn(II) ,Mg(II) and binuclear Zn(II)/Cu(II) and Ni(II)/Cu(II) complexes of new Schiff-base derived from alanine amino acid ester have been synthesized and characterized. They ...
