Some natural compounds of plants including phenols and alkaloids induce mitosis depressive that are blocked cell division. Field dodder (Cuscuta campestris Yunck.) and eastern dodder (Cuscuta monogyna Vahl.) are the most widespread obligatory parasitic species. In the present study, end of summer 2015, field dodder and eastern dodder are collected from Alhagi maurorum Medik. host and Vine (Viti...

A novel 4-[(8-hydroxyquinolin-5-yl)methyl]aminobenzenesulfonamide (HQMABS) was synthesized by optimized reaction of 4-aminobenzenesulfonamide with 5-chloromethyl-8-hydroxyquinoline hydrochloride (CMHQ). Various oxinates of HQMABS were also prepared using Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II) metal salts. All compounds were analyzed by physicochemical, thermogravimetric and spectros...

Five new tetranuclear complexes based on an 8-hydroxyquinoline Schiff base derivative and the β-diketone coligand, [Ln4(acac)4L6(μ3-OH)2]·CH3CN·0.5CH2Cl2 (Ln = Gd (1), Tb (2), Dy (3), Ho (4) and Er (5); HL = 5-(benzylidene)amino-8-hydroxyquinoline; acac = acetylacetonate) have been synthesized, and structurally and magnetically characterized. Complexes 1-5 have similar tetranuclear structures. ...

The kinetics and equilibria of binding of gallium(III) to the 8-hydroxyquinoline (HQ) have been investigated in water and in the presence of sodium dodecyl sulfate (SDS) micelles. Moreover, the pKA1 and pKA2 of HQ and first hydrolysis constant of Ga3+ ion have been measured in water and SDS solution. The analysis of the kinetic and thermodynamic behavior reveals that the reactive form of Ga(III...

The localized corrosion behavior of a galvanic aluminum copper couple was investigated by in situ fluorescence imaging with a fiber-optic imaging sensor. Three different, but complementary methods were used for visualizing remote corrosion sites, mapping the topography of the metal surface, and measuring local chemical concentrations of H+, OH-, and Al3+. The first method is based on a pH-sensi...

The numerous methods for determining magnesium in biological fluids that have been reported in the past have varied from chemical to spectrochemical techniques. Among these various procedures have been included gravimetric, calorimetric, and titrimetric techniques. The gravimetric micromethod based on the precipitation of magnesium B-hydroxyquinoline in hot ammoniacal solution, first utilized b...

In vivo incorporation of a series organometallic photoluminescent complexes in Phaeodactylum tricornutum diatom shells (frustules) is investigated as biotechnological route to luminescent biosilica nanostructures. [Ir(ppy)2bpy]+[PF6]−, [(2,2′-bipyridine)bis(2-phenylpyridinato)iridium(III) hexafluorophosphate], [Ru(bpy)3]2+ 2[PF6]−, [tris(2,2′-bipyridine)ruthenium(II) AlQ3 (tris-(8-hydroxyquinol...

Structures containing 8-hydroxyquinoline scaffold are useful for anticancer drug development. The title ester (5-chloroquinolin-8-yl)-2-fluorobenzoate was prepared by the reaction of 2-fluorobenzoyl chloride with 5-chloro-8-hydroxyquinoline. The structure of the title compound was assigned by diverse spectroscopic techniques. Moreover, a crystallographic study was undertaken and its supramolecu...

In this study, the potential of 8-Hydroxyquinoline grafted SBA-15 to extract of Cu2+ cations from aqueous solutions was investigated. SBA-15 nanoporous silica was chemically grafted with 8-Hydroxyquinoline groupsaccording to the procedure in the literature. The presence of organic groups in the silica framework was demonstrated by FTIR spectrum. The grafted product showed th...
