Penetratin and derivatives acting as antibacterial agents
(Wiley, 2013-06)
The synthesis, in vitro evaluation and conformational study of penetratin and structurally related derivatives acting as antibacterial agents are reported. Among the compounds evaluated here, two methionine sulphoxide ...
Priming with NO controls redox state and prevents cadmium-induced general up-regulation of methionine sulfoxide reductase gene family in Arabidopsis
(Elsevier France-editions Scientifiques Medicales Elsevier, 2016-12)
In the present study we evaluated the pre-treatment (priming) of Arabidopsis thaliana plants with sodium nitroprusside (SNP), a NO-donor, as an interesting approach for improving plant tolerance to cadmium stress. We focused ...
Temporal pattern of neuronal insulin release during Caenorhabditis elegans aging: Role of redox homeostasis
(Facultad de Medicina y CienciaCentro de Biología Celular y Biomedicina CEBICEM, 2019)
The insulin-IGF-1/DAF-2 pathway has a central role in the determination of aging and longevity in Caenorhabditis elegans and other organisms. In this paper, we measured neuronal insulin secretion (using INS-22::Venus) ...
Radiation Chemical Studies of Methionine in Aqueous Solution: Understanding the Role of Molecular Oxygen
(Universidad de Belgrano. Facultad de Ciencias Exactas y Naturales. Investigación, 2010)
The oxidation of methionine is an important reaction in the biological milieu. Despite a few decades
of intense studies, several fundamental aspects remain to be defined. We have investigated in detail the
γ-radiolysis ...
Estudio Comparativo de Proteínas Involucradas en el Balance de Oxido-Reducción en Diferentes Organismos. Caracterización del Sistema de Tiorredoxina en Protozoos y Algas Eucariotas
(2009-03-20)
Todas las formas de vida han desarrollado sistemas enzimáticos eficientes para resistir el daño oxidativo generado por las especies reactivas del oxígeno. El estado redox celular es un mediador crucial de diferentes procesos ...
Type I photosensitized oxidation of methionine
(Wiley Blackwell Publishing, Inc, 2021-01)
Methionine (Met) is an essential sulfur-containing amino acid, sensitive to oxidation. The oxidation of Met can occur by numerous pathways, including enzymatic modifications and oxidative stress, being able to cause relevant ...
Synthesis, spectroscopic characterization, DFT studies, and antibacterial and antitumor activities of a novel water soluble Pd(II) complex with L-alliin
(Elsevier Science BvAmsterdamHolanda, 2013)
Estudio de nuevos actores en el metabolismo antioxidante de protozoos patógenos
(2015-07-03)
La tesis se centra en el estudio de diferentes sistemas antioxidantes presentes en parásitos humanos.
Entamoeba histolytica, un parásito intestinal, se expone a cantidades elevadas de especies reactivas del oxígeno (ERO) ...
