    Antibacterial activity of new [(2-hydroxypropyl)-n-oximino]pyridines
    (ASIAN JOURNAL OF CHEMISTRY, 2008) Sen, Nejdet; Kar, Yakup; Kurbanov, Sultan; Uyanik, Arzu
    The synthesized [(2-hydroxypropyl)-n-oximino]pyridine derivatives has been tested against the pathogenic four Gram-positive bacteria Bacillus cereus (ATCC 11778), Staphylococcus aureus (ATCC 6538), Sarcina lutea (ATCC 934 1) and Streptococs mutans (UCTC 10499) and three Gram-negative bacteria Salmonella typhimurium (1,4,5,12:;: 1,2), Pseudomonas aeruginosa (ATCC 27853) and Escherichia coli (ATCC 29998). Generally, all synthesized compounds (IVa-c) showed strong activity compared to antibiotic drug (cefalexin). However, among this compounds (IVa) showed excellent activity against Bacillus cereus (ATCC 11778), Sarcina lutea (ATCC 9341), Salmonella typhimurium (1,4,5,12:;: 1,2) and Escherichia coli (ATCC 29998) compared to cefalexin.

    Synthesis and Characterization of Copper(Ii) and Nickel(Ii) Complexes of the Schiff Bases Derived From ?3-tetrahydrobenzaldehyde and 2-methyl-?3-tetrahydrobenzaldehyde and Glycine
    (Marcel Dekker Inc., 1998) Güler, Ersin; Sevindir, Hüseyin Cahit; Kurbanov, Sultan; Mirzaoğlu, Ramazan
    Copper(II) and nickel(II) complexes with the Schiff bases derived from ?3-tetrahydrobenzaldehyde or 2-methyl-?3-tetrahydrobenzaldehyde and glycine were synthesized. These compounds have been characterized by elemental analyses, conductivity measurements and infrared spectroscopy. The Schiff base ligands and their complexes have been further characterized by 1H NMR. The results suggest that the Schiff base acts as a bidentate ligand which bonds to the metal ions through the imino nitrogen and carboxylate oxygen. The potassium salts of the Schiff bases are 1:1 electrolytes, but all the complexes are non-electrolytes.
