Polyisoprenylated benzophenone derivatives from Clusia obdeltifolia
(2005)
Two new polyisoprenylated benzophenones along with the known compound 28,29-Epoxyplukenetione A were isolated
from the hexane extract of Clusia obdeltifolia after extensive chromatographic procedures. One of the new ...
QUENCHING OF TRIPLET BENZOPHENONE BY VITAMINS E and C and BY SULFUR CONTAINING AMINO ACIDS and PEPTIDES
(1985)
Abstract— The quenching rate of triplet benzophenone in water and/or water mixtures has been determined employing vitamin C, vitamin E, cystine, cysteine, reduced and oxidized glutathione, methionine and DL‐penicillamine. ...
Benzophenone guttiferone A from Garcinia achachairu Rusby (Clusiaceae) Presents Genotoxic Effects in Different Cells of Mice
(Public Library Science, 2013-11-08)
Benzophenones from natural sources and those of synthetic analogues present several reports of potent biological properties, and Guttiferone A represents a promising medicinal natural compound with analgesic and gastroprotective ...
A new type of Brazilian propolis: Prenylated benzophenones in propolis from Amazon and effects against cariogenic bacteria
(ELSEVIER SCI LTD, 2011)
Ethanol extracts of four propolis samples (E1-E4) from Manaus (Brazilian Amazon) were analysed by HPLC/DAD/ESI-MS/MS and GC/EIMS. The major constituents of E2 and E4 were analysed by NMR ((1)H and (13)C) and ESI/MS/MS. The ...
Rutin association with ethylhexyl methoxycinnamate and benzophenone-3: In vitro evaluation of the photoprotection effectiveness by reflectance spectrophotometry
(COLEGIO FARMACEUTICOS PROVINCIA DE BUENOS AIRES, 2008)
There is a world tendency to the development of sunscreens possessing reduced concentration of UV filters and, yet, with high UVA-UVB protection. This research work proposes the development and in vitro efficacy evaluation ...
