Objective(s): Due to the rapid increased drug resistance to Plasmodium parasites, an urgent need to achieve new antiplasmodial drugs is felt. Therefore, in this study, the new synthetic phenanthroline derivatives were synthesized with antiplasmodial activity. Materials and Methods: A series of 1,10-phenanthroline derivatives containing amino-alcohol and amino-ether substituents were synthesized...

The Zn(2+)-chelating metalloprotease inhibitor 1,10-phenanthroline (phenanthroline, 5-150 microM) elicited dose-dependent contraction of the longitudinal and circular (transverse) musculature of adult male schistosomes. At the same concentrations, phenanthroline did not cause contraction of dispersed individual muscle fibres. The phenanthroline-induced contractions were reduced by the inclusion...

tow new compound of type [(chelate)2cu-oh-cu(chelate)2] x3.nh2o, where chelate=1,10-phenanthroline; x=cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine;  (n=5) have been synthesized and their properties investigated. the complexes show room temperature magnetic moment order of 1.0 b.m. per copper atom. the x-band esr spectrum of powdered samples at room temperature shows typical dm=1 transit...

copper complexes of [cu(phen)(tda)].2h2o(1) and [(phen)2cu(µ-tda) cu(phen)](clo4)2.1.5h2o (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. both complexes were characterized by elemental analysis, ir, uv–vis spectroscopy and cyclic voltammetry. their solid state structures were determined by the single crystal x-ray diffraction method. complex 1 is mononu...

Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...

Abstract Phenanthroline ligands bearing two biphenyl ( L1 ) or tetraarylbenzene L2 substituents have been synthetized and used to prepare bis‐phenanthroline copper(I) complexes. Steric constraints are limited in the case of biphenyl‐substituted ligand [Cu( 2 ](BF 4 has obtained by reaction with [Cu(CH 3 CN) ). In contrast, large enough totally prevent formation corresponding homoleptic complex....

The binding affinity of a series of square planar platinum(II) compounds of the type [Pt(A(L))(I(L))](2+), where A(L) is 1,2-diaminoethane and I(L) are 1,10-phenanthroline (phen), 4-methyl-1,10-phenanthroline (4Mephen), 5-methyl-1,10-phenanthroline (5Mephen), 4,7-dimethyl-1,10-phenanthroline (47Me2phen), 5,6-dimethyl-1,10-phenanthroline (56Me2phen) or 3,4,7,8-tetramethyl-1,10-phenanthroline (34...

5,6-Dibromo-1,10-phenanthroline and 2,9-di-n-butyl-5,6-dibromo-1,10-phenanthroline were polymerized using a Ni catalyst to afford helical polymers in which the phenanthroline moieties are densely stacked on top of each other. Polymerization of the latter monomer using a chiral catalyst led to a preferred-handed helix. This is the first Ni-catalyzed helix-sense-selective polymerization of aromat...

Herein, we report the synthesis, structure and magnetic properties of two mononuclear complexes general formula [Dy(acac)3(L)], where L = 2,2-dimethyl-1,3-dioxolo[4,5-f][1,10] phenanthroline (1) or 1,10-phenanthroline-5,6-dione (2), acac? acetylacetonate anion. A distorted square-antiprismatic N2O6 environment around central Dy(III) ion is formed by three anions a phenanthroline-type ligand. Bo...
