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 ...
Direct detection of the triphenylpyrylium-derived short-lived intermediates in the photocatalyzed degradation of acetaminophen, acetamiprid, caffeine and carbamazepine

Martínez-Haya, Rebeca; Gomis Vicens, Juan; Arqués Sanz, Antonio; Amat Payá, Ana María; Miranda Alonso, Miguel Ángel; Marín García, Mª Luisa (Elsevier, 2018-08-15)

[EN] Advanced oxidation processes are useful methodologies to accomplish abatement of contaminants; however, elucidation of the reaction mechanisms is hampered by the difficult detection of the short-lived primary key ...
MECHANISTIC STUDIES ON THE PHOTOTOXICITY OF ROSUVASTATIN, ITRACONAZOLE AND IMATINIB

Nardi, Giacomo (Universitat Politècnica de València, 2015-03-31)

Photosensitizing effects of xenobiotics are of increasing concern in public health since modern lifestyle often associates sunlight exposure with the presence of chemical substances in the skin. An important number of ...
Singlet oxygen and radical-mediated mechanisms in the oxidative cellular damage photosensitized by the protease inhibitor simeprevir

García-Laínez, Guillermo; El Ouardi, Meryem; Moreno, Alejandro; Lence, Emilio; González-Bello, Concepción; Miranda, Miguel Á.; Andreu, Inmaculada (Elsevier, 2023-01)

[EN] Hepatitis C, a liver inflammation caused by the hepatitis C virus (HCV), is treated with antiviral drugs. In this context, simeprevir (SIM) is an NS3/4A protease inhibitor used in HCV genotypes 1 and 4. It is orally ...
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 ...
Time-resolved kinetic assessment of the role of singlet and triplet excited states in the photocatalytic treatment of pollutants at different concentrations

Martínez-Haya, Rebeca; Gomis, J.; Arques Sanz, Antonio; Marín García, Mª Luisa; Amat Payá, Ana María; Miranda Alonso, Miguel Ángel (Elsevier, 2017)

[EN] A kinetic-based rationale to assess the role of each excited species in thermodynamically favoured photocatalytic processes at different pollutant concentrations, has been developed and illustrated with new experimental ...
