Enzymatic and chemical synthesis of new anticoagulant peptides
(American Chemical Society, 2018-09)
In this study we report the enzymatic synthesis of N-α-[Carbobenzyloxy]-Tyr-Gln-Gln (Z-YQQ), a new anticoagulant tripeptide. It was obtained using phytoproteases from the stems and petioles of Asclepias curassavica L. as ...
Parametric study of the gel-combustion synthesis of nanocrystalline ZrO2-based powders
(Elsevier Science Sa, 2011-12)
In this paper, we report a study of the effect on the powder morphology of zirconia based solid solutions of several parameters of the synthesis by gel-combustion routes, such as fuel, metal/fuel ratio, composition of the ...
Isolation, Synthesis, and Biological Activity of Quindoline, a Valuable Indoloquinoline Natural Product and Useful Key Intermediate
(Georg Thieme Verlag Kg, 2018-04)
Quindoline is one of the simplest naturally occurring monomeric indoloquinoline alkaloids. Chemists exhibited interest in this compound before it was isolated from a natural source. The different approaches toward the total ...
Chemical design and synthesis of unsymmetrical diamino proligands employing a flexible route
(Pergamon-Elsevier Science Ltd, 2012-08)
Three new unsymmetrical diamino proligands with a central alcohol group and four different pendant arms were obtained, employing a five step synthesis. The synthesis of these compounds involves inexpensive and commercially ...
Design, synthesis and biological evaluation of quinoxaline compounds as anti-HIV agents targeting reverse transcriptase enzyme
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-02)
Infection by human immunodeficiency virus still represents a continuous serious concern and a global threat to human health. Due to appearance of multi-resistant virus strains and the serious adverse side effects of the ...
Thermodynamic Assessment of Chemical Equilibrium for the Synthesis of Solketal in the Liquid Phase
(Wiley VCH Verlag, 2021-05-05)
The synthesis of solketal is one of the innovative routes of glycerol valorization to value-added products, and the simulation of the process requires the knowledge of thermodynamic properties that are not still available ...
Plasmon-induced photochemical synthesis of silver triangular prisms and pentagonal bipyramids by illumination with light emitting diodes
(Elsevier Science Sa, 2012-12)
We have grown silver prisms and pentagonal bipyramids, induced by plasmon excitation on a colloidal solution under the irradiation of light emitting diodes of different colors. Two methods of synthesis of the seeds were ...
Effect of synthesis conditions on the nanopowder properties of Ce 0.9Zr0.1O2
(Pergamon-Elsevier Science Ltd, 2011-06)
In this work, the synthesis of nanocrystalline Ce0.9Zr 0.1O2 powders via the gel-combustion method, using different fuels, and following either stoichiometric or non-stoichiometric pH-controlled routes is investigated. The ...
An Eco-friendly Synthesis of Novel 3,5-Disubstituted-1,2-isoxazoles in PEG-400, Employing the Et3N-Promoted Hydroamination of Symmetric and Unsymmetric 1,3-Diyne-indole Derivatives
(Royal Society of Chemistry, 2014-11)
A facile, efficient and atom-economic synthesis of 3,5-disubstituted 1,2-isoxazoles bearing indole moieties, is reported. The synthesis of these isoxazoles was carried out by the triethylamine-promoted reaction of symmetric ...
