(2014)
The present research was conducted to investigate the in vitro cytotoxic activity of
dichloromethane extracts obtained from the leaves of sourpsop (Annona muricata L.) on human
colon cancer cell line HT-29, as an alternative ...
Synthesis, characterization, binding interactions with biomolecules and cytotoxic studies of molybdebocene complexes
(2009)
Bis-(cyclopentadienyl) molybdenum dichloride or molybdenocene dihalides, like other metallocenes dihalides, have shown antitumor properties in different human tumors. In contrast to titanocene dichloride, molybdenocene ...
Optimization of biodiesel production process using recycled vegetable oil
(2010)
Petro diesel toxic emissions and its limited resources have created an interest for the
development of new energy resources, such as biodiesel. Biodiesel is traditionally produced
by a transesterification reaction between ...

(2012)
Nuevos complejos organometálicos fueron sintetizados, partiendo del dicloruro de molibdenoceno (Cp2MoCl2) y cuatro ligandos: L-Acido ascórbico(L-AA), 6-o-palmitoil-L- acido ascórbico (PAA), Etil maltol y D-penicilamina, ...
Functionalization of [60]Fullerene using organometallic complexes and amines
(2008)
The organometallic functionalization of C60 can produce novel materials with potential applications in fields such as material science, electronics, and catalysis. Understanding the structure-dependent electronic and ...
Detection of hydroperoxy complex in the oxidative reactions of myoglobin with hydrogen peroxide
(2008)
A large number of heme enzymes catalyze the heterolysis of hydrogen peroxide (H2O2) and H2O2 is used as a source of oxidizing equivalents for biological oxidative reaction. Despite the increased understanding of the reactions ...
Caracterización química de metabolitos aislados en un extracto con actividad antimicrobiana y antifúngica de la ascidia, Rhopalaea sp. Proveniente del área de Cuajiniquil, Guanacaste, Costa Rica
(2009)
Marine ecosystems have a very large amount of resources, most of them are still partially unknown, and few have been exploited for development of new industrial and toxicological products. The objective of this investigation ...
Ligand displacement reactions of fac-(η2-C60)(η2-phen)M(CO)3 (M = Mo, Cr, and W)
(2009)
A mechanistic description of the ligand exchange reactions of fac-(η2-C60)(η2-phen)M(CO)3 (M = Cr, W and Mo); phen = 1,10-phenanthroline) will be presented in this work. The Lewis bases (L) piperidine (pip), triphenyl ...
Synthesis, chemical and biochemical characterization of TiIV and VIV complexes with anti-tumor activity
(2010)
At the present time in which the metallocene dihalides have shown to possess antitumoral activity, scientists of all around the world have been working with the synthesis and structural modifications to improve their ...
