Photosensitizing properties of compounds related to benzophenone.
Benzophenone is a phototoxic compound with absorption maxima in the ultraviolet A (UVA) and ultraviolet B (UVB) range. Many benzophenone derivatives are known to be photosensitizing. On the other hand, 2-hydroxy-4-methoxybenzophenone is used as a photoprotective agent. The aim of the present study was to analyse a range of benzophenone derivatives and thus examine the effects of molecular chang...
متن کاملTransient absorption spectroscopy detection of sensitized delayed fluorescence in chiral benzophenone/naphthalene systems
Transient absorption spectroscopy has proven to be a powerful tool to investigate the formation and decay of excited singlet states upon triplet-triplet annihilation, following T-T energy transfer from a selectively excited sensitizer. Thus, upon selective excitation of benzophenone (BZP) by laser flash photolysis (LFP) at λ = 355 nm in the presence of naphthalene (NPT), a negative band centred...
متن کاملNTP technical report on the toxicity studies of benzophenone (CAS No. 119-61-9). Administered in feed to F344/N rats and B6C3F mice.
Benzophenone is used as a photoinitiator, a fragrance enhancer, an ultraviolet curing agent, and, occasionally, as a flavor ingredient; it is also used in the manufacture of insecticides, agricultural chemicals, and pharmaceuticals and is an additive for plastics, coatings, and adhesives. In 14-week studies conducted to determine the toxicity of benzophenone, groups of 10 male and 10 female F34...
متن کاملDetermination of key diffusion and partition parameters and their use in migration modelling of benzophenone from low-density polyethylene (LDPE) into different foodstuffs.
The mass transport process (migration) of a model substance, benzophenone (BZP), from LDPE into selected foodstuffs at three temperatures was studied. A mathematical model based on Fick's Second Law of Diffusion was used to simulate the migration process and a good correlation between experimental and predicted values was found. The acquired results contribute to a better understanding of this ...

Bisphenol A and benzophenone, diphenyl compounds, were regioselectively hydroxylated, reduced, and glycosylated by the cultured plant cells of Eucalyptus perriniana. Three known biotransformation products and two new products, 2-(3-b-D-glucopyranosyloxy-4-hydroxyphenyl)-2-(4-b-D-glucopyranosyloxyphenyl)propane and 2-(3b-D-glucopyranosyloxy-4-b-D-glucopyranosyloxyphenyl)-2-(4-hydroxyphenyl)propa...
