A new Schiff base ligand as salt (KL) was synthesized using potassium salt of DL-β-phenylalanine and 2-hydroxy-1-naphthaldehyde.
Two binuclear complexes of this ligand, [M
2L
2(CH
3COO)
2] (M = Cu(II), Ni(II)) have been synthesized and characterized by elemental analyses, IR, UV spectra, and molar conductance.
Their prohibitive action on the superoxide anion free radical (O
2−·) was estimated by the NBT illumination deoxidizing method (Methionine-lactoflavin illumination method). The results suggested
that the ligand and its complexes had the prohibitive action on O
2−·.
