Crystal structure of bis(μ2-methanolato-κO:κO)hexamethylbis(μ2-triphenylacetato-κO:κO′)bis(μ2-triphenylacetato-κ2O,O′:κO)dialuminiumdilanthanum tolue…

The complex [{La(Ph3CCOO)2(Me3AlOMe)}2] has an La2(μ-OCO)4 core, contains the carboxylate ligands in μ2-κ1 O:κ1 O′ bridging and μ2-κ2 O,O′:κ1 O semi-bridging coordination modes, and displays La—C interactions with the π-system of a phenyl ring.
Cleavage of Ge–Ge and Sn–Sn Triple Bonds in Heavy Group 14 Element Alkyne Analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6(C6H3-2,6-iPr2)2) by Rea…

The reactions of heavier group 14 element alkyne analogues (EAriPr4)2 (E = Ge, Sn; AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) with the group 6 transition-metal carbonyls M(CO)6 (M = Cr, Mo, W) under UV irradiation resulted in the cleavage of the E–E triple bond and the formation of the complexes {AriPr4EM(CO)4}2 (1–6), which were characterized by single crystal X-ray diffraction as well as by IR and multinuclear NMR spectroscopy. Single-crystal X-ray structural analyses of 1–6 showed that the complexes have a nearly planar rhomboid M2E2 core with three-coordinate group 14 atoms. The coordination geometry at the group 6 metals is distorted octahedral formed by four carbonyl groups as well as two br…
The synergistic effect exerted by the HDAC inhibitor SAHA and the sesquiterpene lactone parthenolide on triple negative breast canc er cells
2014
Triple-negative breast cancer (TNBC) is a subtype o f breast cancer, insensitive to endocrine therapy. Chemotherapy is the main form of treatment, but is accompanied by a high rate of recidivism. The sesquiterpene lactone Parthenolide (PN) exerts a cy totoxic effect on MDA-MB231 cells, a TNBC cell line (1), but was ineffective at low doses (2-5μM). This repr esents an obstacle for a therapeutic utilization of PN. We supposed, in line with other authors (2), that PN c auses a protective response, which at low doses pre vails on the cytotoxic effect. With the aim of inhibiting this protective effect we have shown that pre-trea tment of MDA-MB231 cells with SAHA (2-5μM), an histone deace tylat…
Producción de blastocistos diploides, heteroparentales a partir de pre-embriones tripronucleareshumanos procedentes de FIV e ICSI
2015
En Biomedicina, particularmente en el campo de reproducción humana asistida, la mejora de las técnicas implícitas, así como la puesta a punto de otras, requiere de la realización de estudios y ensayos previos con pre-embriones, preferiblemente de la misma especie, con potencial de desarrollo y que sean genéticamente normales. La disponibilidad y uso de estos pre-embriones no debe provocar conflictos éticos ni legales, no siendo, los pre-embriones humanos generados con una finalidad reproductiva la opción más inmediata. En la búsqueda de modelos pre-embrionarios humanos válidos, homólogos a aquéllos reproductivamente viables, presentamos el presente trabajo de tesis, cuyo objetivo principal …
Acid–base properties of functionalised tripodal polyamines and their interaction with nucleotides and nucleic acids
2010
Novel, highly positively charged tripodal polyamines with appended heterocyclic moieties revealed an intriguing panel of protonation species within the biologically relevant range. Studied compounds bind nucleotide monophosphates by mostly electrostatic interactions but only the imidazole analogue showed selectivity toward UMP in respect to other nucleotides. Strong binding of all the studied compounds to both ds-DNA and ds-RNA is to some extent selective toward the latter, showing rather rare RNA over DNA preference.

Evaluación de los cambios en la respuesta linfocitaria en el microambiente tumoral como factor pronóstico y predictivo de respuesta a la quimioterapi…
2019
El tratamiento neoadyuvante en el cáncer de mama (CM) permite estudiar marcadores subrogados que puedan predecir respuesta clínica y supervivencia. La respuesta completa patológica (RCp) definida como la ausencia de tumor infiltrante en la mama y axila en la pieza quirúrgica se asocia a mejor supervivencia. En los tumores triple negativos el tratamiento de elección es la combinación de quimioterapia, antraciclinas y taxanos son los esquemas con mayor evidencia, junto con carboplatino alcanzando tasas de RCp del 35-60 %. Sin embargo, no disponemos de factores predictivos que identifiquen qué subgrupo obtendrá mayores tasas de RCp. Existe evidencia que niveles altos de infiltrado linfocitario…
