Communic Acids: Occurrence, Properties and Use as Chirons for the Synthesis of Bioactive Compounds
Barrero, Alejandro F.; Herrador del Pino, María del Mar; Arteaga Burón, Pilar; Fernández Arteaga, Jesús
; Arteaga, Alejandro F. (MDPI, 2012-02)
Communic acids are diterpenes with labdane skeletons found in many plant species, mainly conifers, predominating in the genus Juniperus (fam. Cupresaceae). In this review we briefly describe their distribution and different ... -
Comparison of the Simple Cyclic Voltammetry (CV) and DPPH Assays for the Determination of Antioxidant Capacity of Active Principles
Fernández Arteaga, Jesús; Ruiz Montoya, Mercedes; Palma López, Alberto; Alonso Garrido, Gema; Pintado, Sara; Rodríguez Mellado, José Miguel (MDPI, 2012)
Antioxidant activity of a number of small (low molecular weight) natural compounds found in spices, condiments or drugs (gallic acid, sesamol, eugenol, thymol, carvacrol, vanillin, salicylaldehyde, limonene, geraniol, ... -
Desarrollo e implementación de métodos electroquímicos para determinar la capacidad antioxidante de muestras orgánicas
Palma López, Alberto (Universidad de Huelva, 2015)
El estrés oxidativo es uno de los procesos bioquímicos estudiados de mayor relevancia en los últimos años que surge como consecuencia de un desequilibrio entre las sustancias antioxldantes y prooxidantes. Este fenómeno ... -
Determination of antioxidant activity of spices and their active principles by Differential Pulse Voltammetry
Palma López, Alberto; Ruiz Montoya, Mercedes; Fernández Arteaga, Jesús; Rodríguez Mellado, José Miguel (American Chemical Society, 2014)
The anodic oxidation of mercury in the presence of hydrogen peroxide in differential pulse voltammetry (DPV) was used to determine the antioxidant (AO) character of radical scavengers. Hydroperoxide radical is formed at ... -
Diseño de moléculas con actividad biológica : síntesis e Implicaciones en química supramolecular
(Universidad de Huelva, 2019)Uno de los grandes desafíos dentro de la Química Supramolecular es conseguir imitar el comportamiento de las biomoléculas. Para ello, es necesario el diseño de compuestos sintéticos que tengan gran afinidad y selectividad ... -
Diseño y caracterización de compuestos organoboro fluorescentes y sus aplicaciones funcionales
(Universidad de Huelva, 2020)La presente Memoria de Tesis Doctoral titulada “Diseño y Caracterización de Colorantes Organoboro Fluorescentes y sus Aplicaciones Funcionales” está dirigida hacia el diseño, caracterización fotofísica y aplicación de ... -
Easy Access to a Cyclic Key Intermediate for the Synthesis of Trisporic Acids and Related Compounds
González Delgado, José Ángel; Escobar, Gustavo; Fernández Arteaga, Jesús; Barrero, Alejandro F. (MDPI, 2014)
The synthesis of a cyclohexane skeleton possessing different oxygenated functional groups at C–3, C–8 and C–9, and a 1,6-double bond has been accomplished in 10 steps with an overall 17% yield. This compound is a key ... -
Five-Component Self-Assembly of Cucurbituril-Based Hetero-pseudorotaxanes
Parente Caldeira Carvahlo, Cátia Diana; Domínguez Hidalgo, Zoe; Domínguez Linares, Cristina; El- Sheshtawy, Hamdy S.; Da Silva, José Paulo; Fernández Arteaga, Jesús; Pischel, Uwe (Wiley Open Access, 2017)
[5]Pseudorotaxanes can be obtained by self-sorting using heteroditopic guests and various cucurbituril homologues as hosts. The assembly and chemically induced disassembly of the pseudorotaxanes can be monitored by measuring ... -
Functionalization of biopolymers with reactive groups to be used as thickeners in oil media
Gallego Calvo, Rocío (Universidad de Huelva, 2015)
During the last decades, there has been an increasing interest in the use of natural components in a wide variety of manufactured products, due to the general tendency to promote the replacement of non-renewable raw materials ... -
Influence of functionalization degree on the rheological properties of isocyanate-functionalized chitin- and chitosan-based chemical oleogels for lubricant applications
Gallego Calvo, Rocío; González, Mercedes; Fernández Arteaga, Jesús; Valencia Barragán, Concepción; Franco Gómez, José María (MDPI, 2014)
This work deals with the influence of functionalization degree on the thermogravimetric and rheological behaviour of NCO-functionalized chitosan- and chitin-based oleogels. Chitosan and chitin were functionalized using ... -
Isocyanate-Functionalized Chitin and Chitosan as Gelling Agents of Castor Oil
Gallego Calvo, Rocío; Fernández Arteaga, Jesús; Valencia Barragán, Concepción; Franco Gómez, José María (MDPI, 2013)
The main objective of this work was the incorporation of reactive isocyanate groups into chitin and chitosan in order to effectively use the products as reactive thickening agents in castor oil. The resulting gel-like ... -
A Minor Dihydropyran Apocarotenoid from Mated Cultures of Blakeslea trispora
Fernández Barrero, Alejandro; Herrador del Pino, María del Mar; Arteaga Burón, Pilar; Fernández Arteaga, Jesús (MDPI, 2012)
The heterocyclic C15 apocarotenoid 1 was isolated from mated cultures of the strains F986 (+) and F921 (−) of Blakeslea trispora. This new compound formed during sexual interaction is a minor constituent of the culture ... -
Toward UV-Triggered Curing of Solvent-Free Polyurethane Adhesives Based on Castor Oil
Borrero López, Antonio María; Guzmán, David B; González-Delgado, José Antonio; Fernández Arteaga, Jesús; Valencia Barragán, Concepción; Pischel, Uwe; Franco Gómez, José María (American Chemical Society, 2021-08-10)
An o-nitrobenzyl-protected precursor was used as a phototrigger for the release of the diamine cadaverine in polyurethane adhesives based on castor oil as a renewable source of polyol and organic diisocyanates. This ...
