2-Phenylaminonaphthoquinones and related compounds: Synthesis, trypanocidal and cytotoxic activities (Elsevier, 2014)A series of new 2-aminonaphthoquinones and related compounds were synthesized and evaluated in vitro as trypanocidal and cytotoxic agents. Some tested compounds inhibited epimastigote growth and trypomastigote viability. ...
-
(2004)We report that oxidative phosphorylation and Ca2+ uptake processes are enhanced in liver mitochondria isolated from benzo[a]pyrene (B[a]P)-treated rats. The carcinogen did not affect either the respiratory control index ...
-
(Elsevier, 2013)Objectives: To evaluate the effect of benznidazole on endothelial activation in a murine model of Chagas disease. Methods: A low (30 mg/kg/day) and a high (100 mg/kg/day) dose of benznidazole were administered to mice ...
-
(AMER SOC MICROBIOLOGY, 2008)L-Buthionine (S,R)-sulfoximine (BSO) at a dose of 220 mg/kg of body weight/day showed an anti-Trypanosoma cruzi effect in infected mice, increasing their survival rate and decreasing the parasitemias and parasite burden ...
-
(Society of Biology of Chile, 2010)There are approximately 7.8 million people in Latin America, including Chile, who suffer from Chagas disease and another 28 million who are at risk of contracting it. Chagas is caused by the flagellate protozoan Trypanosoma ...
-
(ELSEVIER, 2007)Alkyl esters of gallic acid inhibited the respiration rate of mouse sarcoma 786A and mouse mammary adenocarcinoma TA3 cell lines and its multiresistant variant TA3-MTX-R more effectively than gallic acid, both in the ...

Dehydroepiandrosterone effect on Plasmodium falciparum and its interaction with antimalarial drugs (2013)Dehydroepiandrosterone (DHEA) inhibits glucose 6-phosphate dehydrogenase (G6PDH) of different species and may potentially decrease intracellular glutathione. Therefore, it can have and enhance anti-parasitic action against ...
-
(Elsevier Espana S.L.U, 2019)Feedback is fundamental in methodologies such as Team-Based Learning (TBL) because it deepens learning by identifying deficiencies of the process. In the setting of curricular innovation in the Faculty of Medicine, University ...
-
(Society of Biology of Chile, 2004)Proteins rich in sulfhydryl groups, such as metallothionein, are present in several strains of the parasite Trypanosoma cruzi, the etiological agent of Chagas' disease. Metallothionein-like protein concentrations ranged ...
-
(Public Library Science, 2018)Trypanosoma cruzi is exposed during its life to exogenous and endogenous oxidative stress, leading to damage of several macromolecules such as DNA. There are many DNA repair pathways in the nucleus and mitochondria ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-03)Electrochemical and ESR studies were carried out in this work with the aim of characterizing the reduction mechanisms of 4-substituted and 1,4-disubstituted 7-nitroquinoxalin-2-ones by means of cyclic voltammetry in DMSO ...
-
(Universidad de Chile, 2016)Gracias al descubrimiento de las aplicaciones anticancerígenas del cisplatino, el interés por estos compuestos y sus propiedades ha aumentado, dando altas expectativas en la farmacéutica. En esta tesis se propuso que ...
-
(Universidad de Chile, 2022)El déficit de tratamientos eficaces para la enfermedad de Chagas ha llevado a la búsqueda de nuevas sustancias con potencial terapéutico. Los productos naturales poseen una gran variedad de motivos estructurales químicos, ...
-
(Universidad de Chile, 2015)La Tripanosomiasis americana o mal de Chagas es una enfermedad potencialmente mortal, causada por el parásito protozoario Trypanosoma cruzi (T. cruzi), cuya principal vía de infección es a través de las heces del insecto ...

Evaluación de la capacidad antioxidante y tripanocida de nuevos compuestos hidroxilados de cumarinas (Universidad de Chile, 2015)El estrés oxidativo es causado por un desequilibrio entre la producción de especies reactivas de oxígeno (radicales libres) y una disminución en los antioxidantes. Con el tiempo, este desajuste en el equilibrio entre ...
-
(Bentham Science, 2016)With the aim of finding new chemical entities based on coumarin and chalcone scaffolds, new hybrid compounds 2-5 were designed and synthesized. The trypanocidal activity of these compounds was tested against the epimastigote, ...
-
(Elsevier, 2017)The synthesis of unsymmetrical ferrocenyl and cyrhetrenyl azines [(h5-C5H4)-CR¼N-N¼CH-2-C4H2X-5-NO2]M (M¼Re(CO)3, Fe(h5-C5H5); R¼H, CH3,X¼O, S) has led to the development of new derivativesof 5-nitroheterocycles as potential ...
-
(Elsevier Inc., 1996)Glutathione (GSH), trypanothione (T(SH)2) and glutathionyl spermidine (GSH-SP) concentrations were determined in the Tulahuen and LQ strains and the DM 28c clone of Trypanosoma cruzi. The concentrations of GSH, T(SH)2 and ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-05-15)A series of indazole N-oxide derivatives have been synthesized and their antichagasic and leishmanocidal properties studied. 3-Cyano-2-(4-iodophenyl)-2H-indazole N-1-oxide exhibited interesting antichagasic activity on the ...
