This doctoral thesis is focused on the investigation and development of new compounds directed to different cancer and tropical diseases targets. Drug resistance, as well in cancer as in tropical diseases, is a hurdle which ...
Sphingolipids (SLs) are essential structural and signaling molecules of eukaryotic cells. An important group of SLs metabolites are those showing a phosphate group at the C1‒ OH. Among them, sphingosine‒1‒phosphate (S1P) ...
En la present tesi doctoral s’ha desenvolupat una estratègia per obtenir els esquelets dels quatre alcaloides licopodi representatius a partir d’un mateix intermedi sintètic comú 1, de manera semblant al procés que té lloc ...
1. It was observed that the interaction of imines and isocyanides in the presence of a Lewis acid can lead to a variety of scaffolds including α-aminoamides, α-aminoamidines, indoles and diiminoazetidines. The reaction ...
[spa] La enfermedad de Alzheimer (EA) es el tipo de demencia más común. En los últimos años su prevalencia se ha incrementado preocupantemente, considerándose la epidemia del siglo XXI. Hasta ahora solo se han conseguido ...
En les últimes dècades, l’increment del consum de sucres, especialment de fructosa, s’ha associat al desenvolupament de la obesitat i d’alteracions metabòliques com ara diabetis, hipertensió i malalties cardiovasculars. ...
La enfermedad de Alzheimer (EA) es el tipo de demencia progresiva más común. En base al incremento de la prevalencia esperada, es considera la epidemia del siglo XXI. En consecuencia, surge una gran necesidad de encontrar ...
The first objective of this Thesis was the study of the preparation of octhydro-1H-cyclopenta[b]pyridines and octahydro-1H-indoles, through the synthesis of (R)-phenylglycinol derived tricyclic lactams. Following the ...
Epoxieicosatrienoic acids acids (EETs) are endogenous chemical mediators derived from arachidonic acid that show anti-inflammatory, antihypertensive, analgesic, angiogenic and antiatherosclerotic effects. Soluble epoxide ...
Type 2 diabetes (T2D) is a multifactorial disease that comprises metabolic defects in multiple organs. Several studies have shown that the presence of a chronic low-state inflammatory process induces the development of ...
[cat] Els alcaloides indòlics monoterpènics del grup leuconolam-leuconoxina-mersicarpina [(–)- mersicarpina, (–)-leuconoxina, (+)-melodinina E] i la (–)-kopsiyunnanina K presenten una interessant activitat biològica juntament ...
The distinctive reactivity of isocyanides has been recognised as an advantageous characteristic for the formation of heterocyclic compounds. In the present manuscript new synthetic possibilities are explored involving the ...
La población mundial está envejeciendo, la mayoría de países del mundo están experimentando un aumento en el número y la proporción de personas mayores. Los últimos datos publicados de la ONU en 2017 informan que se espera ...
Factores ambientales como el ejercicio, el estrés o la dieta contribuyen a la patogénesis de enfermedades asociadas al deterioro cognitivo y al envejecimiento, modulando mecanismos de expresión génica que son susceptibles ...
This thesis has its main focus on developing multi-functional nanomaterials, that we called nano- and microtools through two different approaches, top-down to provide support and bottom up to give functionality to prepare ...
Alzheimer’s disease (AD) is the most common form of dementia and one of the most important health-care problems in the world, due to its high prevalence and unaffordable personal and economic impact. Moreover, current ...
Drugs of abuse represent a global problem not only at a health level, but also at a social and economic extent. Recently, a tidal wave of new emerging psychoactive substances has completely modified the illicit drug market, ...
Although sygma-aryl and sygma-vinylpalladium(II) complexes are commonly used as electrophiles in C—C bond forming reactions, recent research has demonstrated that the same palladium intermediates can also react with ...
L’objectiu de la present tesi doctoral consisteix en desenvolupar molècules policícliques de baix pes molecular que tinguin com a diana tres canals iònics específics: la viroporina A/M2 del virus de la grip, el receptor ...
Actualment, el tractament de la malaltia d’Alzheimer (MA) és una necessitat mèdica no coberta, ja que només existeixen tres grups de fàrmacs aprovats que no són suficientment eficaços pel control de la malaltia. La naturalesa ...
