Biradical vs singlet oxygen photogeneration in suprofen cholesterol systems

Palumbo, Fabrizio; Bosca Mayans, Francisco; Morera Bertomeu, Isabel María; Andreu Ros, María Inmaculada; Miranda Alonso, Miguel Ángel (Beilstein-Institut, 2016-06-14)

Cholesterol (Ch) is an important lipidic building block and a target for oxidative degradation, which can be induced via free radicals or singlet oxygen (1O2). Suprofen (SP) is a nonsteroidal anti-inflammatory drug that ...
Enhanced photo(geno)toxicity of demethylated chlorpromazine metabolites

Palumbo, Fabrizio; García Lainez, Guillermo; Limones Herrero, Daniel; Coloma, María Dolores; Escobar, Javier; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel; Andreu Ros, María Inmaculada (Elsevier, 2016)

Chlorpromazine (CPZ) is an anti-psychotic drug widely used to treat disorders such as schizophrenia or manic-depression. Unfortunately, CPZ exhibits undesirable side effects such as phototoxic and photoallergic reactions ...
Estudio de las reacciones radicalarias del colesterol en diadas modelo

Palumbo, Fabrizio (Universitat Politècnica de València, 2014-11-28)

[EN] Cholesterol (Ch) is one of the most important building blocks of cell membranes. It is also one of the main targets for oxidation via Type I hydrogen abstraction (HA), which leads to a variety of physiological ...
Hydrogen Abstraction from the C15 Position of the Cholesterol Skeleton

Palumbo, Fabrizio; Andreu Ros, María Inmaculada; Brunetti, M.; Schmallegger, Max; Gescheidt, Georg; Neshchadin, Dmytro; Miranda Alonso, Miguel Ángel (American Chemical Society, 2019-12-06)

[EN] Cholesterol (Ch) is an integral part of cell membrane, where it is prone to oxidation. In humans, oxidation of Ch is commonly linked to various pathologies like Alzheimer's disease, atherosclerosis, and even cancer, ...
Investigation of metabolite-protein interactions by transient absorption spectroscopy and in silico methods

Limones Herrero, Daniel; Palumbo, Fabrizio; Vendrell Criado, Victoria; Andreu Ros, María Inmaculada; Lence, Emilio; González-Bello, Concepción; Miranda Alonso, Miguel Ángel; Jiménez Molero, María Consuelo (Elsevier, 2020-02-05)

[EN] Transient absorption spectroscopy in combination with in silico methods has been employed to study the interactions between human serum albumin (HSA) and the anti-psychotic agent chlorpromazine (CPZ) as well as its ...
Solvent effects in hydrogen abstraction from cholesterol by benzophenone triplet excited state

Andreu Ros, María Inmaculada; Palumbo, Fabrizio; Tilocca, Fedele; Morera Bertomeu, Isabel María; Bosca Mayans, Francisco; Miranda Alonso, Miguel Ángel (American Chemical Society, 2011)

[EN] Hydrogen abstraction from the C-7 position of cholesterol (Ch) by triplet excited benzophenone (BZP) exhibits remarkable solvent-dependence in product studies. Kinetic measurements on the intramolecular version of ...
Spectroscopic characterization of dipicolinic acid and its photoproducts as thymine photosensitizers

Nardi, Giacomo; Lineros-Rosa, Mauricio; Palumbo, Fabrizio; Miranda Alonso, Miguel Ángel; Lhiaubet, Virginie Lyria (Elsevier, 2021-01-15)

[EN] Dipicolinic acid (DPA), present in large amount in bacterial spores, has been proposed to act as an endogenous photosensitizer in spore photoproduct formation. The proposed mechanism involves a triplet-triplet energy ...
Steric-shielding vs sigma-pi orbital interactions in triplet-triplet energy transfer

Andreu Ros, María Inmaculada; Morera Bertomeu, Isabel María; Palumbo, Fabrizio; Sastre Navarro, German Ignacio; Bosca Mayans, Francisco; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry: Chemical Science, 2015)

he influence of non-covalent σ–π orbital interactions on triplet–triplet energy transfer (TTET) through tuning of the donor excitation energy remains basically unexplored. In the present work, we have investigated ...
Topological control in radical reactions of cholesterol in model dyads

Neshchadin, Dmytro; Palumbo, Fabrizio; Sinicropi, M. Stefania; Andreu Ros, María Inmaculada; Gescheidt, Georg; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry, 2013)

Cholesterol is one of the most important building blocks of cell membranes. It is also one of the main targets for oxidation via Type I hydrogen abstraction (HA), which leads to a variety of physiological consequences in ...
