Oxidation of amino acids by chlorpromazine cation radical and co-catalysis by chlorpromazine
(SciRes, 2012)
The long-tem use of chlorpromazine (CPZ) may cause severe side effects. This property of CPZ might be related to pro-oxidant effects of the chlorpromazine cation radical (CPZ•+), which can be easily generated by catalytic ...
Tryptophan photooxidation promoted by new hybrid materials prepared by condensation of naphthalene imides with silicate by the sol-gel process
(ELSEVIER SCIENCE SA, 2009)
Three novel hybrid organic/inorganic materials were synthesized from 4-substituted (NO(2), Br, H) 1,8-naphthalene imide-N-propyltriethoxysilane by the sol-gel process. These materials were obtained as a xerogel and partially ...
Quantification of tryptophan in plasma by high performance liquid chromatography
(Sociedade Brasileira de Química, 2012)
A simple, rapid and selective method using high-performance liquid chromatography with ultraviolet detection (267 nm) was applied for the determination of tryptophan in plasma. Separation was carried out on a C18 column ...
Surface-enhanced Raman scattering study of L-tryptophan
(2009)
Surface-enhanced Raman scattering (SERS) spectra of tryptophan (Trp) were obtained. A unique SERS spectrum of Trp, corresponding to the most stable conformation and orientation on the metal surface, is observed after a ...
Digestible tryptophan levels in diets for pigs weighing 15 to 30 kg

Tryptophan hydroxylase is modulated by L-type calcium channels in the rat pineal gland
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Calcium is an important second messenger in the rat pineal gland, as well as cAMP. They both contribute to melatonin synthesis mediated by the three main enzymes of the melatonin synthesis pathway: tryptophan hydroxylase, ...
The interaction of bothropstoxin-I (Lys49-PLA(2)) with liposome membranes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Bothropstoxin-I (BthTx-I) is a Lys49-PLA(2) from the venom of the snake Bothrops jararacussu, which permeabilizes biological and artificial membranes by a mechanism independent of lipid hydrolysis. This mechanism has been ...
