-
(2002)We have studied the O2/O2·- redox couple on the HMDE in DMSO aprotic media, obtaining optimal conditions of both oxygen concentration and scan rate in order to avoid oscillatory phenomena. By choosing the oxygen concentration ...
-
(ELSEVIER SCIENCE, 2004-01-15)PA-824 (2-nitro-6-(4-trifluoromethoxy-benzyloxy)-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine) is being tested as antituberculosis drug. Little is known on the action mechanism of PA-824; however the reduction of the nitro ...

(ELSEVIER SCIENCE, 2001-09-21)Megazol (2-amino-5-(1-methyl-5-nitro-2-imdazolyl)-1,3,4-thiadiazol, CAS 19622-55-0) and related nitroimidazole compounds are being tested as antichagasic drugs. Little is known on the mode of action of megazol. However, ...
-
(ELSEVIER SCIENCE, 2002-08-23)We have chosen 4-nitroimidazole (4-NIm) as a prototype of nitroimidazolic compounds in order to carry out an exhaustive cyclic voltammetric study in protic media, 0.1 M Britton-Robinson buffer+0.3 M KCl with ethanol as a ...
-
Cyclic voltammetric study of the nitro radical anion from nitrendipine generated electrochemically (1991)Electrochemical studies on nitrendipine using mixed aqueous/dimethylformamide (DMF) solvent have allowed us to generate the one-electron reduction product, the nitro radical anion, RNO.-2. The voltammetric technique has ...
-
(ELSEVIER SCIENCE SA, 2004-08-01)The system of I-octanol-beta-cyclodextrin in 0.5 M HClO4 at Pt electrodeposited on an Au/quartz crystal (Pt/Au/Q) has been studied by cyclic voltammetry (CV), the electrochemical quartz crystal microbalance (EQCM) and ...
-
Cyclic voltammetry and digital simulation of the electroreducction of ortho-and meta-nitro aryl ... (Sociedad Chilena de Química, 1999)Cyclic voltammetry (CV) and digital simulation methods are utilezed to elucidate the mechanism of electrochemical reduction of a series of nitro aryl 1,4-dihydropyridines im protic (aqueous) and mixed media. The experimental ...

Cyclic voltammetry and digital simulation of the electroreduction of ortho- and meta-nitro aryl ... (1999)Cyclic voltammetry (CV) and digital simulation methods are utilized to elucidate the mechanism of electrochemical reduction of a series of nitro aryl 1,4-dihydropyridines in protic (aqueous) and mixed media. The experimental ...
-
(1993)EPR has been used to investigate the radicals postulated as intermediates in the intramolecular electron transfer and dehalogenation of p-nitrobenzyl bromide (p-NBBr) in DMSO and DMFA at room temperature. The electrochemical ...
-
(PERGAMON-ELSEVIER, 2007-04-20)The heterogeneous electron transfer reaction for the reduction of some nitroso aromatic derivatives in aqueous-alcoholic medium was studied on both mercury and glassy carbon electrodes (GCE) by using cyclic voltammetry ...
-
(Universidad de Chile, 2023)Recent empirical studies on labor income dynamics depict recessions as times when employed households face a higher risk of large and long-lasting income declines. Motivated by this evidence, we build a real business cycle ...
-
(Universidad de Chile. Facultad de Economía y Negocios, 1995-12)A two-country model of growth is developed with exogenous fluctuations in the rate of technological progress. Technological growth in the leading country follows a random walk, while in the lagging country the rate of ...
-
(Lippincott Williams & Wilkins, 2017)The purinergic P2X2 receptor (P2X2R) is an adenosine triphosphate-gated ion channel widely expressed in the nervous system. Here, we identified a putative cyclin-dependent kinase 5 (Cdk5) phosphorylation site in the full-size ...
-
(Elsevier Science ltd., 1995)Bioactivity guided fractionation of the dichloromethane extract from Psoralea glandulosa yielded the isolation of a diasteromeric mixture of cyclobakuchiols A and B as possible anti-inflammatory active compounds.

(Springer, 2015)The preparation and structural elucidation of the 2 alpha-cyclodextrin/decylamine inclusion compound (IC) by proton nuclear magnetic resonance, rotating frame overhauser effect spectroscopy and powder X-ray diffraction ...
-
(MDPI, 2021)This article describes the synthesis and characterization of beta-cyclodextrin-based nano-sponges (NS) inclusion compounds (IC) with the anti-tumor drugs melphalan (MPH) and cytoxan (CYT), and the addition of gold nanoparticles ...
-
(MDPI, 2021)In drug delivery, one widely used way of overcoming the biopharmaceutical problems present in several active pharmaceutical ingredients, such as poor aqueous solubility, early instability, and low bioavailability, is the ...
