“…Schiff bases obtained from the salicylaldehydes are popular polydentate ligands coordinated in neutral forms. Recently, metal complexes of Schiff bases are gaining popularity because of their antibacterial, antifungal and antitumor activities [2][3]. El-ajaily et al (4) studied the antibacterial activities of the Schiff base derived from the salicylaldehyde and cysteine and its Mn (II), Co(II), Ni (II), Cu (II) and Cd (II) complexes on some pathogenic bacteria.…”

A new chain of Schiff base complexes made up of Cu (II), Co (II), Cd (II),Ni (II), and Mn (II) ions derivatives were obtained by the condensation of 4-dimethyl-aminobenzaldehyde, and 4-aminoantipyrin and some amino acids. The structures of all synthesized complexes were established on the basis of their elemental analysis (UV, FTIR, and 1 HNMR). The study of X-ray crystallographic shows that the compound (Z)-4-((4-(dimethylamino)benzylidene)amino)-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one (L 5 ) crystallized in monoclinic system with space group of C2/c and the unit cell dimensions are a= 17.7916, b= 6.8610, c= 29.7199, α =90.000 β =101.326 γ = 90.000., Z = 8 and V = 3557.20 Å 3 .The antibacterial activity of the complexes are tested against Bacillus subtilis, Bacillus cereus and Pseudomonas aeruginosa.

“…This band is absent in the spectra of metal(II) complexes, indicating coordination through the deprotonated phenolic OH group [35]. Moreover, it was evidenced by the shift in position of νCO (aromatic carbon and phenolic oxygen) at 1319 cm -1 [36] to the lower frequency region in the spectra of complexes [37]. However, the strong band observed at 1675 cm -1 in the free ATS ligand due to azomehtine group vibration is shifted towards lower frequencies in the complexes by (28-37 cm -1 ), suggesting that azomethine group is involved in coordination [38,39].…”

“…Chelating ligands containing N, S and O donor atoms show broad biological activity and are of special interest because of the variety of ways in which they are bonded to metal ions. These ligands can be classified by the number of site that gives electrons to the ion metallic (single claw Bidentate, tridentate, Tetradentate, etc.,) [4][5][6][7][8][9], it is known that the existence of metal ion bonded to biologically active compounds may enhance their activities Schiff base ligands with nitrogen donor atoms of the azomethine group and anther donor atoms of the Schiff base ligand such as oxygen of carboxylic group afforded stable complexes with various transition metals. Beta-Lactam considered important item of antibiotics that contain a (C=O) group in β-Lactam ring in structural [10].…”

The present report is concerned with the synthesis novel Schiff base ligand by condense 6-Amino Penicillinic acid with Salicyldehyde. The ligand was characterized by 1 H-NMR, 13 C-NMR, mass spectrometry, UV-Vis and FT-IR studies. The ligand have got more than one moiety which are capable of chelation, therefore complexes of Co(II), Ni(II), Cu(II), and Zn(II) were prepared. These complexes were characterized by UV-Vis, FT-IR, magnetic susceptibility and Molar conductivity studies. All these techniques indicate 1:2 stoichiometry of synthesized complexes. In all the complexes, Schiff base ligand acts as a tridentate ligand. Finally, the ligand and complexes have been screened for their antibacterial activity against four types of bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus facials and Proteus mirabilis) then it isolated from different classes of ulcerative infections while L showed to be tridentate ligand with single negative charge through three active groups, L has been associated with metal ions to form the claw complexes to get octahedral shape. The prepared ligand and its complexes illustrated a good inhibitory ability towards the three varieties bacteria (Staphylococcus aureus, Pseudomonas aeruginosa, and Proteus mirabilis), while the four complexes failed to be suggested in treatment of ulcers that caused by Streptococcus facials. So, the prepared compounds could be good alternatives to the common drugs which are used in treatment of ulcers.
