Antibacterial cobalt(II), nickel(II) and zinc(II) complexes of nicotinic acid-derived Schiff-bases

Antibacterial cobalt(II), nickel(II) and zinc(II) complexes of nicotinic acid-derived Schiff-bases. Chohan, Zahid H.; Rauf, Abdul; Noreen, Sobia; Scozzafava, Andrea; Supuran, Claudiu T. (Department of Chemistry, Islamia University, Bahawalpur, Pak.Chemicals with cas numbers 476437-48-6 and 1761-61-1 also play role.). Journal of Enzyme Inhibition and Medicinal Chemistry, 17(2), 101-106 (English) 2002 Taylor & Francis Ltd. CODEN: JEIMAZ. ISSN: 1475-6366. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 10 Nicotinic acid derived Schiff bases and their transition metal [cobalt(II), Ni(II) and Zn(II)] complexes were prepd. and characterized by phys., spectral and anal. data. The Schiff bases act as deprotonated tridentate ligands for the complexation of the above mentioned metal ions. These 12 [M(L)2] complexes (HL = 2-aminonicotinic acid-5-substituted salicylaldehyde Schiff base) showed an octahedral geometry of the metal ions.Several reagents such as 5345-47-1 is used here. For detg. the effect of metal ions upon chelation, the Schiff bases and their complexes were screened for antibacterial activity against several pathogenic strains of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The new metal derivs. reported here were more bactericidal against one or more bacterial species as compared to the uncomplexed Schiff bases. ..
