Catalisis asimetrica en reacciones de cicloadicion mediante complejos quirales de Cu(II)

2009

Se ha sintetizado una nueva familia de ligandos de tipo hidroxioxazolina a partirdel ¨¢cido (1S)©cetop¨ªnico. Estos ligandos han sido utilizados en la cat¨¢lisisenantioselectiva de reacciones de Diels©Alder entre 3©alquenoil©2©oxazolidonas ydiferentes dienos, utilizando Cu(OTf)2 como sal met¨¢lica. La estereoqu¨ªmica absolutade los aductos de Diels©Alder depende de la estereoqu¨ªmica del anillo de oxazolina delligando. El mejor resultado se obtiene con el ligando derivado del (1R,2S)©aminoindanol.Se ha introducido por primera vez sustratos bidentados de tipo N©¨®xido de 2©alquenoilpiridina en reacciones catalizadas enantioselectivamente. Estos sustratos sonm¨¢s reactivos que las correspondi…

Síntesis enantioselectiva de guayanos y norguayanos naturales a partir de (+)-dihidrocarvona.

2004

Los sesquiterpenos desempeñan funciones de comunicación y defensa en los organismos vivos que los sintetizan y han sido utilizados por el hombre desde tiempos ancestrales y se continúan utilizando en la industria alimentaria, cosmética, médica etc. La síntesis constituye un método alternativo para su obtención, ya que se encuentran en la naturaleza en cantidades muy pequeñas.La pureza óptica influye de manera decisiva sobre su actividad biológica.La síntesis parcial a partir de precursores quirales naturales asequibles comercialmente constituye la estrategia más útil para la obtención de sesquiterpenos enantioméricamente puros.Esta Tesis Doctoral tiene como objetivo la obtención de guayanos…

Non-Thermal Ultrasonic Extraction of Polyphenolic Compounds from Red Wine Lees

2020

This study presents the results of conventional aqueous (CE) and non-conventional ultrasound-assisted (UAE) extractions of polyphenolic compounds from lees extracts of red wine varieties (Merlot and Vranac). The effect of ultrasound extraction time (t, s), and amplitude (A,%) from a 400 W ultrasound processor with different ultrasonic probes diameters (Ds, mm) on the amount and profile of polyphenolic compounds in the obtained extracts was investigated and compared to CE. The optimal conditions resulting in maximum extraction of phenolic compounds were: Probe diameter of 22 mm, amplitude 90% and extraction time for Vranac wine lees 1500 s and for Merlot wine lees extraction time of 1361 s. …

Designing biochar properties through the blending of biomass feedstock with metals: Impact on oxyanions adsorption behavior

2018

Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify biochar physico-chemical properties and its behavior as adsorbent. Six different compounds were used for metal-blending: AlCl3, Cu(OH)2, FeSO4, KCl, MgCl2 and Mg(OH)2. Pyrolysis experiments were performed at 400 and 700 °C and the characterization of biochar properties included: elemental composition, thermal stability, surface area and pore size distribution, Zeta potential, redox potential, chemical structure (with nuclear magnetic resonance) and adsorption behavior of arsenate, phosphate and nitrate. Metalblending strongly affected biochars' surface charge and redox potential. Moreover, it incre…

Acute tissue damage induced by monopolar microelectrodes and radiofrequency in vocal cords after transoral cordectomy

2021

Abstract Introduction: In 2006 and 2009, we reported the levels of acute and chronic tissue damage after cordectomy associated with use of the microlectrodes using high frequency energy. In 2010, we shifted to radiofrequency rather than high frequency electrogenerators. Objective: The aim of this study is to evaluate acute tissue damage in the larynx after cordectomy using microelectrodes coupled to a radiofrequencygenerator. Methods: We studied 22 patients with a stage T1 glottic squamous cell carcinoma. The patients were randomly assigned to the two operating mode: cutting or coagulation (11 patients each mode). The strength of the study is that there are no previous studies on the effect…

New Tetromycin Derivatives with Anti-Trypanosomal and Protease Inhibitory Activities

2011

Four new tetromycin derivatives, tetromycins 1-4 and a previously known one, tetromycin B (5) were isolated from Streptomyces axinellae Pol001(T) cultivated from the Mediterranean sponge Axinella polypoides. Structures were assigned using extensive 1D and 2D NMR spectroscopy as well as HRESIMS analysis. The compounds were tested for antiparasitic activities against Leishmania major and Trypanosoma brucei, and for protease inhibition against several cysteine proteases such as falcipain, rhodesain, cathepsin L, cathepsin B, and viral proteases SARS-CoV M(pro), and PL(pro). The compounds showed antiparasitic activities against T. brucei and time-dependent inhibition of cathepsin L-like proteas…
