Silicon (IV) Complexes of Schiff Base : Preparation and Characterization
A total of three new silicon (IV) complexes of Schiff base have been synthesized by the reaction of silicon tetrachloride with Schiff base ligands L1 (C16H16N2O2), L2 (C14H12N2O2) and L3 (C13H11NO2).The complexes obtained were characterized qualitatively and quantitatively by using micro-elemental analysis, FTIR spectroscopy, 1 H and 13 C NMR spectroscopy. From the spectral studies we could con...
متن کاملPreparation of CuO nanoparticles by thermal decomposition of double-helical dinuclear copper(II) Schiff-base complexes
In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...
متن کاملSchiff Base Adducts of Hemoglobin
Normal and sickle erythrocytes were exposed in vitro to millimolar concentrations of 31 different carbonyl compounds. Schiff base (imine) linkages were formed with amino groups of intracellular hemoglobin. Adducts were isolated by gel electrofocusing and could be dissociated by dialysis. Aromatic aldehydes proved more reactive than aliphatic aldehydes, and ketones were unreactive. The influence...
متن کاملDesign and synthesis of antituberculars: preparation and evaluation against Mycobacterium tuberculosis of an isoniazid Schiff base.
OBJECTIVES Enzymatic acetylation of the antitubercular isoniazid (INH) by N-acetyltransferase represents a major metabolic pathway for INH in human beings. Acetylation greatly reduces the therapeutic activity of the drug, resulting in underdosing, decreased bioavailability and acquired INH resistance. Chemical modification of INH with a functional group that blocks acetylation, while maintainin...
متن کاملMetal Complexes of Macrocyclic Schiff-Base Ligand: Preparation, Characterisation, and Biological Activity
A new macrocyclic multidentate Schiff-base ligand Na4L consisting of two submacrocyclic units (10,21-bis-iminomethyl-3,6,14,17-tricyclo[17.3.1.1]tetracosa-1(23),2,6,8,10,12(24),13,17,19,21,-decaene-23,24-disodium) and its tetranuclear metal complexes with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) are reported. Na₄L was prepared via a template approach, which is based on the condensation reacti...
