The synthesis of 3,3-dimethyl fentanyl and its lactame analogue
(Journal of the Serbian Chemical Society, 1996)
An efficient synthesis of some novel analogues of fentanyl, a well known central analgesic, has been developed. Thus, 3,3-dimethyl fentanyl(9) and its 2-oxo derivative 7 were prepared in 9 and 8 steps, respectively. In the ...
Purification of the anti-IgE monoclonal antibody E1 from ascitic fluid
(Journal of the Serbian Chemical Society, 1996)
Contemporary biochemical methods for protein purification were applied for the isolation of anti-IgE monoclonal antibody E1 from mouse ascitic fluid. The yield of monoclonal antibody E1 in each of the isolated fractions ...
Conformational study of fentanyl and its analogs.2. Conformational space and electronic properties of ohmefentanyl
(Journal of the Serbian Chemical Society, 1996)
The conformational space and electronic properties of the two physiologically active stereoisomers of ohmefentanyl have been studied by molecular mechanics and semiempirical molecular orbital (PM3) calculational methods. ...
The synthesis and biological evaluation of 3β-hydroxylanosta-7,9-dien-32-al
(Journal of the Serbian Chemical Society, 1996)
The synthesis of the title compound a key intermediate for the synthesis of other DHL derivatives, is reported. The aldehyde 1 and the diol 9 were tested on several enzymes involved in the cholesterol biosynthetic pathway. ...
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 ...
Methane metathesis at a Cationic Iridium Center
(Amer Chemical Soc, Washington, 1996)
Synthesis and structure of aquamethanol-2',2'''-(2,6-pyridin-diyldiethylidene)-dioxamohydrazidocobalt(II) perchlorate
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The complex [Co(H(2)L)(H2O) (MeOH)](ClO4)(2)[H(2)L] = 2',2triple prime-(2,6-pyridindiyl-diethylidene) -dioxamohydrazide] has been prepared by direct and template syntheses and characterized by elemental analysis, IR ...
Steroidal geminal dihydroperoxides and 1,2,4,5-tetraoxanes: Structure determination and their antimalarial activity
(Elsevier Science Inc, New York, 1996)
Cholestane-derived gem-dihydroperoxides and tetraoxanes were synthesized starting from 5 alpha- and 5 beta-cholestan-3-ones by acid-catalyzed addition of hydrogen peroxide to the ketone. They were characterized by IR, NMR, ...
