Template-stereocontrolled [2 + 2] photoreactions directed by surface recognition on hydrophilic functionalized carbon materials
(Royal Society of Chemistry, 2018-04)
Supramolecular assistance of the regioselective synthesis of single dimers from [2 + 2] photoreactions surface-directed by multivalent H-bonding exo-templates based on hydrophilic carbon materials (HCMs) is highlighted for ...
Resveratrol isoforms and conjugates: A review from biosynthesis in plants to elimination from the human body
(2020-01-01)
The natural isomers of resveratrol, cis- and trans-resveratrol, are natural phenolic substances synthetized via the shikimate pathway and found in many sources, including grapes, peanuts, blackberries, pistachios, cacao, ...

The quenching of indolic compounds by monosubstituted benzenes and the photoreaction with chlorobenzene
(Royal Society of Chemistry, 2003-08)
The quenching of the excited singlet of indole and its methyl derivatives by monosubstituted benzenes has been studied in three solvents of different polarities and bimolecular quenching rate constants have been determined. ...
Photoreaction and photopolymerization studies on phenoxazin dyes/diphenyliodonium chloride salt
(Elsevier Science Sa, 2007-04)
The photophysics and photochemistry of the dyes resazurin (Rz) and resorufin (Rf) in absence and presence of diphenyliodonium chloride (DPIC) were investigated in water at pH 10. The dye/DPIC combination undergoes photoreaction ...
Acidity and photolability of ruthenium salen nitrosyl and aquo complexes in aqueous solutions
(ELSEVIER SCIENCE SA, 2008)
The photochemical behavior of nitrosyl complexes Ru(salen)(NO)(OH(2))(+) and Ru(salen)(NO) Cl (salen = N, N`-ethylenebis-(salicylideneiminato) dianion) in aqueous solution is described. Irradiation with light in the 350-450 ...
An FT-EPR investigation of the anomalous CIDEP in photoreactions of chromone and chromone-2-carboxylic acid with alcohol induced by hydrochloric acid
(Elsevier Science Sa, 2006-12)
The anomalous net absorptive CIDEP spectra observed in the photoinduced hydrogen abstraction reaction of chromone (CR) and chromone-2-carboxylic acid (CRCA) from 2-propanol with addition of hydrochloric acid (HCl) were ...
Bupropion and its photoreactive analog (±)-SADU-3-72 interact with luminal and non-luminal sites at human α4β2 nicotinic acetylcholine receptors
(Pergamon-Elsevier Science Ltd, 2016-09)
The interaction of (±)-bupropion [(±)-BP] with the human (h) α4β2 nicotinic acetylcholine receptor (AChR) was compared to that for its photoreactive analog (±)-2-(N-tert-butylamino)-3′-iodo-4′-azidopropiophenone [(±)-SADU-3-72]. ...
Mechanistic analysis on the photochemistry of the anti-inflammatory drug etoricoxib in aqueous solution. Cytotoxicity of photoproducts
(Elsevier Science Sa, 2020-03)
Photophysical and photochemical properties of the non-steroidal anti-inflammatory drug Etoricoxib was analyzing in aqueous media at different pH values. The mechanistic and kinetic aspects of the photodegradation processes ...
Profilometry of semiconductor components by two-colour holography with Bi12TiO20 crystals
(2009-09-14)
We studied the shape measurement of semiconductor components by holography with photorefractive Bi12TiO20 crystal as holographic medium and two diode lasers emitting in the red region as light sources. By properly tuning ...
