Isolation and partial characterization of a lectin from the marine sponge Crambe crambe
(Journal of the Serbian Chemical Society, 1996)
A lectin was isolated from the marine sponge Crambe crambe. The lectin is a monomeric glycoprotein with relative molecular mass of 14000. It agglutinates sheep and human red blood cells. The agglutination was found to be ...
The preparation of N-alkyl acyclic imides
(Journal of the Serbian Chemical Society, 1996)
An optimized method for the preparation of a little known class of compounds, acyclic imides, is described. First, the N-metalation of selected secondary am des was examined, using various bases and solvents. The most ...
Preparation and characterization of meridional isomers of uns-cis-(ethylenediamine-N,N'-di-3-propionato)cobalt(III) complexes with some β-amino acids
(Journal of the Serbian Chemical Society, 1996)
The meridional geometrical isomers of uns-cis-(ethylenediamine-N,N ′-di-3-propionato)cobalt(III) complexes with anions of β-alanine, β-amino-buteric and β-amino-isobuteric acids were prepared in the reaction of sodium ...
The preparation of an isoxazole derivative of 4-hydroxycoumarin
(Serbian Chemical Soc, Belgrade, 1998)
A method for preparation of an isoxazole derivative of 4-hydroxycoumarin, 3-phenyl-5-(4-hydroxy-3-coumarinyl)-isoxazole has been described. The reaction sequence includes addition of bromine to 3-cinnamoyl-4-hydroxycoumarin, ...
Synthesis and characterization of s-cis-bis(ethylenediamine-N,N′-diacetato)-μ-O,O′-glycinato-μ- hydroxo-dichromium(III)monohydrate
(Journal of the Serbian Chemical Society, 1997)
The reaction between s-cis-diaqua-(ethylenediamine-N,N′-diacetato)-chromium(III) nitrate and glycine (mole ratio 1:1, pH = 6, 80 °C, 2 h) results in the formation of two nonelectrolytic compounds. One of them was identified ...
