title: Ternary complexes of palladium (II) with levamisole and L-amino acids.
abstract: The complexes of general formula [(LMS)2Pd(amino acid)]Cl with LMS = levamisole, and amino acid = L-alanine, L-phenylglycine, L-phenylalanine, L-valine, L-methionine, and L-proline, were synthesized by the interaction of [(LMS)2PdCl2] with the sodium salts of L-amino acids. The newly synthesized complexes are characterized by elemental analysis, conductivity, magnetic susceptibility, optical rotation measurements, and UV-Vis, IR and 13C NMR spectral data. Levamisole is coordinated to palladium via the N-7 nitrogen and the amino acids through the amino nitrogen and carboxylate oxygen, except for L-methionine which binds the metal via nitrogen and sulfur atoms. Optically active [(LMS)2Pd(amino acid)]Cl complexes are obtained when L-amino acids or D,L-amino acids are used for the synthesis of these complexes. L-Methionine and L-proline complexes induce new cell forms in Baker's yeast (Saccharomyces cerevisiae) cells.
