Article
Three freshwater microalgae ( Spirogyra sp ., Cosmarium sp . , and Cosmarium blytii ) collected from several locations in Gran Canaria have been studied to explore their potential as a novel source of bioactive compounds for biotechnological applications. Soluble carbohydrates were quantified after extraction with 3M HCl at 100ºC, ranging from 35.8...

The biochemical composition of three novel selected microalgae strains (Chlorophyta) was evaluated to confirm their potential possibilities as new sustainably produced biomass with nutritional, functional, and/or biomedical properties. Extracts from cultured Pseudopediastrum boryanum, Chloromonas cf. reticulata, and Chloroidium saccharophilum exhib...

In this study, the effects of plants on the performance and bacterial community structure of palm mulch-based vertical flow constructed wetlands was studied. The wetlands were built in August 2013; one of them was planted with Canna indica and Xanthosoma sp., and the other one was not planted and used as a control. The experimental period started i...
Conference Paper

The high level of solar radiation and the high temperature prevailing in the regions of Canary Islands forces plants to develop defense mechanisms against ultraviolet radiation and excessive production of free radicals through the accumulation of antioxidant substances. This prompted us to evaluate the phenolic content and the antioxidant activity...
Article
In the present chapter, we have evaluated the total phenolic contents and antioxidant activities of crude extracts from a red alga, Corallinaelongata. The phenolic compounds in the extracts have been identified and quantified by reverse-phase high-performance liquid chromatography. Phloroglucinol was by far the predominant polyphenol found in the e...
Article
Water, water/methanol (1/1), methanol and ethanol crude extracts from a brown alga Stypocaulon scoparium were examined for total phenolic contents (TPC) using Folin–Ciocalteu method. DPPH scavenging assay was performed to measure the radical scavenging activities (RSA) of the extracts. Results showed a significant association between the antioxidan...
Article
This paper studies the cytotoxic effect induced by four known natural sesquiterpene lactones (tatridin A, tamirin, reynosin, ineupatorolide A) and one synthetic derivative (tatridin A diacetate) on the myeloid leukemia cell lines HL-60 and U937. Tatridin A diacetate and ineupatorolide A were found to be the most cytotoxic compounds with growth inhi...

In the CNS, NPY has been implicated in obesity and feeding, endocrine function and metabolism. Potent and selective rNPY antagonists will be able to probe the merits of this approach for the treatment of obesity. We report the synthesis and preliminary evaluation of some hydrazide derivatives as antagonists of rNPY.
Article
The adrenergic system plays a major role in controlling energy expenditure. Thus, cathecolamines mobilize energy-rich stores by stimulating lipolysis in fat cells and thermogenesis in brown adipose tissue. Our study was focused on the cyclization of the pharmacophore aryloxypropanolamine found in compounds with a well-known β 3-adrenergic agonist a...
Article
The synthesis of new cyclic compounds, arylethanolamine derivatives, with potential beta3-adrenoceptor agonist selectivity, which are associated with thermogenesis and regulation of insulin release, are described. Oxazolidine, oxazolidin-2-one, and perhydro-1,4-oxazine derivatives were obtained. The preliminary evaluation of the pharmacological eff...

Project
The ATOPFe Project will study the effects of pH, temperature, and organic matter (TOC) on Fe (II) oxidation kinetics and its persistence in the ocean. Three specific regions: polar, subtropical and submarine volcanic regions, have been selected as the fundamental basis for comparing laboratory studies and developing a kinetic model for iron in the context of ocean acidification and warming. The main goal of the EACFe project is to investigate which compounds and mechanisms determine the presence of Fe(II) in the marine environment and how the presence of organic matter, ocean acidification and global warming affect them.
Project
The main goals of the EACFe project is to investigate which compounds and mechanisms determine the presence of Fe(II) in the marine environment and how ocean acidification and global warming affect them. To achieve these goals we will combine the studies in the Atlantic Subarctic region, one of the most sensitive to ocean acidification, with studies in the lab using individual organic compounds and the exudates from cultures of phytoplankton. In the lab studies we will consider the different variables independently in order to define the contribution of each one to the process.
