(Universidad de Chile, 2007)La modificación química de polímeros, especialmente las poliolefinas, ha sido tema de estudio en los últimos años, con el propósito de obtener nuevos materiales. Estos polímeros modificados pueden ser utilizados como agentes ...
-
(2002)The effect of Boldo and black tea infusions on the pro-oxidant effects of vitamin B-2, riboflavin (R-F), when exposed to the action of visible light was studied. The amounts of antioxidants present in Boldo and tea infusions ...
-
(MDPI AG, 2014)The kinetics and spectral characteristics of the transients formed in the reactions of • OH and •N3 with quinoxalin-2(1H)-one (Q), its methyl derivative, 3-methylquinoxalin- 2(1H)-one (3-MeQ) and pyrazin-2-one (Pyr) were ...
-
(Sociedade Brasileira de Quimica, 2010)The aim of this study was to determine the influence of the substituent groups on the photostability of eight boldine derivatives, including some oxazole and oxazinone derivatives, in order to increase the sunscreen ...
-
(2003)Time-resolved photolysis studies of riboflavin (RF) were carried out in the presence and absence of α-, βH- and βL-crystallins of bovine eye lens. The transient absorption spectra, recorded 5 μs after the laser pulse, ...
-
(2005)The new oxoisoaporphines 7H-dibenzo[de,h]quinolin-7-one, 5-methoxy-7H-dibenzo[de,h]quinolin-7-one, 5-methoxy-6-hydroxy-7H-dibenzo[de,h] quinolin-7-one, 5-hydroxy-7H-dibenzo[de,h]quinolin-7-one and 5-methoxy-6H-dibenzo[de ...

(2007)Coupling nicotinoyl chloride with 3,4-dimetoxyphenethylamine under Bischler-Napieralski cyclization afforded the isoquinoline (4) in good yield. This latter was used as starting material to obtain with only hydrobromic ...
-
(Elsevier, 2017)A new calix[4]arene thiourea derivative bearing a benzothiazolyl moiety (L) was synthetized and characterized by single crystal X-ray, NMR and ESI-TOF. The binding ability of the bifunctional receptor towards several ions ...
-
(Sociedade Brasileira de Quimica, 2016)Glycolipids are biomolecules composed of a lipid chain (lipophilic) and a monosaccharide or oligosaccharide as hydrophilic group. Their chemical structure and biological role make them undoubtedly good candidates for a ...
