The reaction of 1,3-bis(4,6-dimethylpyridyl-2-imino)isoindoline and palladium acetate in methanol selectively yields the expected acetato palladium N,N,N-chelate or a cyclometalated tetranuclear dimer depending on the stoichiometry of the reactants.

In the title compound, C(10)H(9)NO, the amino and the hydr-oxy groups act both as a single donor and a single acceptor in hydrogen bonding. In the crystal, mol-ecules are connected via chains of inter-molecular ⋯N-H⋯O-H⋯ inter-actions, forming a two-dimensional polymeric structure resembling the hydrogen-bonded mol-ecular assembly found in the crystal structure of naphthalene-1,5-diol. Within t...

Insects from a variety of Orders have been shown to detoxify phenols by conjugation with glucose and this mechanism has been suggested as a systematic biochemical characteristic of insects (Smith, 1955a). The phenols may be foreign compounds or may be those formed in the normal course of metabolism (Smith, 1955b, 1964; Kent & Brunet, 1959; Stay & Roth, 1962; Butenandt, Biekert, Kubler & Linzen,...

The purpose of this study was to investigate the response of physicochemical properties of gerbera (Gerbera Jamesonii L.) to silica nanoparticles (Nanoparticle-SiO2) and calcium chelate (Ca-Chelate) in nutrient solutions. A factorial experiment based on completely randomized design with two factors was conducted in four replicates. The first factor the concentration of Nanoparticle-SiO2 in nutr...

The angular correlation of the 173-247 keV gamma-ray cascade after the electron-capture decay of (111)In is strongly perturbed when the 1-p-nitrophenyl-ethylenediaminetetraacetate chelate of (111)In(8+) is added to a solution containing rabbit antibody to dinitrophenyl groups. The radioactive chelate can be displaced by the addition of dinitrophenyllysine or unlabeled chelate. The average assoc...

It is suggested that under physiological conditions (> 1 mM Mg(2+)) MgATP binds to myosin to form a chelate involving the two reactive sulfhydryl sites (SH(1) and SH(2)). The stability of the chelate structure results in marked inhibition of the myosin ATPase in the presence of millimolar magnesium ion. The inhibitory effect of magnesium ion can be eliminated chemically by blocking either the S...

An experiment was conducted to investigate the effects of dietary supplementation of copper chelates in the form of methionine, chitosan and yeast on the performance of laying hens. Four hundred ISA Brown layers, 84 wks old, were assigned to 4 treatments: control, 100 ppm Cu in methionine chelate (Met-Cu), 100 ppm Cu as chitosan chelate (Chitosan-Cu) and 100 ppm Cu as yeast chelate (Yeast-Cu). ...

Black-bone silky fowl iron(II)-oligopeptide chelate was synthesized from iron(II) solution and the black-bone silky fowl oligopeptide, which was extracted from the muscle protein of black-bone silky fowl (Gallus gallus domesticus Brisson). Orthogonal array analysis was used to determine the optimal conditions for the iron(II)-oligopeptide chelate preparation. Ultraviolet-visible (UV-Vis) spectr...
