Dansyl-labeled cholic acid as a tool to build speciation diagrams for the aggregation of bile acids

Gómez Mendoza, Miguel; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (American Chemical Society, 2012-12-27)

Bile acids (BAs) are a family of natural steroids biosynthesized from cholesterol in the liver that tend to form aggregates in solution. A fluorescent derivative of cholic acid, namely 3 alpha-Dns-ChA, was employed as a ...
Direct covalent attachment of DNA microarrays by rapid thiol-ene "click" chemistry

Escorihuela Fuentes, Jorge; Bañuls Polo, María-José; Grijalvo-Torrijo, Santiago; Eritja, Ramón; Puchades, Rosa; Maquieira Catala, Ángel (American Chemical Society, 2014-03)

[EN] A rapid strategy for the covalent immobilization of DNA onto silicon-based materials using the UV-initiated radical thiol-ene reaction is presented in this study. Following this approach, thiol- and alkene-modified ...
Excited-state interactions in diastereomeric flurbiprofen-thymine dyads

Bonancía Roca, Paula; Vayá Pérez, Ignacio; Climent Olmedo, María José; Gustavsson, Thomas; Markovitsi, Dimitra; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel (American Chemical Society, 2012-09-06)

Excited-state interactions between (S)- or (R) fluorescence (S)- or (R)-FBP) and thymidine (dThd) covalently linked in dyads 1 or 2 have been investigated. In both dyads, the only emitting species is (FBP)-F-1*, but with ...
Intraprotein formation of a long wavelength absorbing complex and inhibition of excited state deprotonation in a chiral hydroxybiphenyl

Bonancía Roca, Paula; Vayá Pérez, Ignacio; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel (American Chemical Society, 2012-12-27)

The two enantiomers of 2-(2-hydroxybiphenyl-4-yl)propanoic acid ((S)- and (R)-BPOH) have been selected as probes for human serum albumin (HSA). Photophysical characterization in the absence of protein led to emission maxima, ...
Retarded photooxidation of cyamemazine in biomimetic microenvironments

Limones Herrero, Daniel; Pérez Ruiz, Raúl; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel (Wiley, 2014-10)

Cyamemazine (CMZ) is a neuroleptic drug that mediates cutaneous phototoxicity in humans. Here, the photobehavior of CMZ has been examined within (1)-acid glycoproteins, - and -cyclodextrins and SDS micelles. In all these ...
Stereodifferentiation in the intramolecular singlet excited state quenching of hydroxybiphenyl-tryptophan dyads

Bonancía Roca, Paula; Vayá Pérez, Ignacio; Markovitsi, Dimitra; Gustavsson, Thomas; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry, 2013)

The photochemical processes occurring in diastereomeric dyads (S, S)-1 and (S, R)-1, prepared by conjugation of (S)-2-(2-hydroxy-1,1'-biphenyl-4-yl) propanoic acid ((S)-BPOH) with (S)- and (R)-Trp, have been investigated. ...
Triplet excited state behavior of naphthalene-based pseudopeptides in the presence of energy donors

Bonancía Roca, Paula; Vigara, Laura; Galindo, Francisco; Luis, Santiago V.; Jiménez Molero, María Consuelo; Miranda Alonso, Miguel Ángel (American Chemical Society, 2012-08-23)

In this work, the triplet state behavior of naphthalene-based pseudopeptides with amide-based macrocyclic or lateral chain substructures has been investigated in the presence of benzophenone and/or biphenyl, as suitable ...
