Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...

Major histocompatibility complex (MHC) class II deficiency is a primary immunodeficiency disease characterized by abnormality of MHC class II molecules surface expression on peripheral blood lymphocytes and monocytes. Clinical manifestations include extreme susceptibility to viral, bacterial, and fungal infections but the immunodeficiency is not as severe as SCID (severe combined immunodeficien...

a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

Several novel mononuclear Zn(II) complexes, [Zn(bpy)L2], where bpy=2,2’-bipyridine and L=monoanions of phenylcyanamide (pcyd), 4-methylphenylcyanamide (4-Mepcyd), 3,5-dimethylphenylcyanamide(3,5-Me2pcyd),4-methoxyphenylcyanamide(4-MeOpcyd), 3,5-dimeth-oxyphenylcyanamide (3,5-MeO2pcyd), 3-chlorophenylcyanamide (3-Clpcyd), 2,3-dichlo...

General Considerations. Unless stated otherwise, all reactions and procedures were carried out in a VAC Atmosphere Nexus glovebox or using standard Schlenk techniques under a nitrogen atmosphere. Solvents were received from Sigma Aldrich, degassed and dried using a Vac Atmosphere Solvent Purifier system and stored over 3Å molecular sieves. Prior to drying, toluene, benzene and pentane were trea...

The genetic analysis of common neurological disorders will be a difficult and protracted endeavour. Genetics is only one of many disciplines that will be required but it has already thrown considerable light on the aetiology of several major neurological disorders through the analysis of rare inherited subgroups. The identification of individual susceptibility genes with variants of smaller eff...

Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determine...
