Idemudia, Omoruyi G. published the artcileSynthesis and characterization of bioactive acylpyrazolone sulfanilamides and their transition metal complexes: single crystal structure of 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-one sulfanilamide, COA of Formula: C17H14N2O2, the publication is Bioinorganic Chemistry and Applications (2015), 1-15, database is CAplus and MEDLINE.
Two Schiff base ligands Ampp-Sn (1) and Bmpp-Sn (2), afforded by a condensation reaction between sulfanilamide and the resp. acylpyrazolone carbonyl precursors, their Mn(II), Co(II), Ni(II), and Cu(II) complexes prepared by the reaction of ligands and corresponding metal salts in aqueous solutions, were synthesized and then characterized by both anal. and spectroscopic methods, in a view to developing new improved bioactive materials with novel properties. From elemental anal., spectroscopic and TGA results, transition metal complexes, with octahedral geometry having two mols. of the bidentate keto-imine ligand each, are proposed. The single crystal structure of Bmpp-Sn according to x-ray crystallog. showed a keto-imine tautomer type of Schiff base, having three intramol. bonds, one short N2···H2···O3 hydrogen bond of 1.90 Å and two long C13···H13···O2 and C32···H32···O3 hydrogen bonds of 2.48 Å. A moderate to low biol. activities were exhibited by synthesized compounds when compared with standard antimicrobial agents on screening the synthesized compounds against Staphylococcus aureus, Bacillus pumilus, Proteus vulgaris, and Aeromonas hydrophila for antibacterial activity and against free radical 1,1-diphenyl-2-picryl-hydrazyl (DPPH) for antioxidant activity.
