(ELSEVIER SCIENCE BV, 2008-05-15)Finasteride in hydroalcoholic solutions (ethanol/Britton-Robinson buffer, 30/70) exhibits cathodic response in a wide range of pH (-0.5 to 12) using differential pulse (DPP) and tast polarography (TP). The reduction peak ...
-
(ELSEVIER SCIENCE, 2000-12-01)In this report we have chosen ethyl-m-nitrobenzoate (EMNB) as a prototype of a nitroaromatic compound in order to carry out a detailed cyclic voltammetric study focused on the coupled chemical reaction of the generated ...
-
(2011)For the first time, a simple differential pulse voltammetry methodology for direct determination of benserazide in presence of levodopa in tablets was developed without any redox mediator, modified electrodes, or the ...
-
(1990)The electrochemical reduction of 7-nitro-1,4-benzodiazepin-2-ones and of their acid hydrolysis products, 2-amino-5-nitrobenzophenones, was studied by polarography and cyclic voltammetry in a solvent - buffer system containing ...
-
(ROYAL SOC CHEMISTRY, 1990-04)The electrochemical reduction of 7-nitro-1,4-benzodiazepin-2-ones and of their acid hydrolylis products, 2-amino-5-nitrobenzophenones, was studies by polarography and cyclic voltammetry in a solvent - buffer system containing ...
-
(Elsevier B.V., 1997)A differential pulse polarographic method for the quantitative determination of ketorolac is described. Ketorolac is an antiinflammatory-analgesic agent that is directly electroreducible at the mercury electrode. The ...
-
(Wiley-VCH Verlag, 1997)Nimesulide, N‐(4‐nitro‐2‐phenoxyphenyl)methanesulfonamide is an antiinflamatory analgesic agent that is both reducible at the mercury electrode and oxidizable at the glassy carbon electrode. Nimesulide in hydroalcoholic ...
-
(WILEY-V C H VERLAG GMBH, 2003-01)The electrochemical behavior of 2-(5-amino- 1,3,4-oxadiazolyl)-5-nitrofuran (NF359) and its comparison with well known drugs such as nifurtimox (NFX) and nitrofurazone (NFZ) in protic, mixed and aprotic media by cyclic ...
-
(2002)Ruthenium complexes of the type [RuL(CO)2Cl2], [RuL2Cl2], [RuL2(CO)(H2O)](PF6)2, [RuL2Cl]2(PF6)2, [RuL2(CO)Cl](PF6), and [RuL2(CO3)]·3H2O (where L is a bipyridine or phenanthroline derivative) dissolved in aqueous ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2007-04)Long chain aliphatic alcohols have been used as model compounds to develop a preparative method for a water-soluble material, which could be a carrier for triacontanol, a highly hydrophobic plant growth regulator. New ...
-
(Springer, 2014)Parasitic illnesses are major causes of human disease and misery worldwide. Among them, both amebiasis and Chagas disease, caused by the protozoan parasites, Entamoeba histolytica and Trypanosoma cruzi, are responsible ...
-
(Frontiers Media, 2016)Serotonin (5-HT) is a neurotransmitter that plays an important role in neuronal plasticity. Variations in the levels of 5-HT at the synaptic cleft, expression or dysfunction of 5-HT receptors may alter brain development ...
-
(Universidad Andres Bello, 2019)The work of Catherine malabou, based mainly on the philosophical re-elaboration of the concept of 'plasticity', offers a new reading of time and, punctually, of the writing of history. In the following essay we intend to ...
-
(2012)A new withanolid amine was isolated from Dunalia spinosa (Solanaceae). Its relative stereochemistry was determined using FT-IR, 1H and 13C NMR spectroscopies and high resolution mass spectrometry. Nicotine was also isolated; ...
-
(2000)Electrocyclic transformation between cis-butadiene and cyclobutene has been studied at the HF and DFT levels with 6-311G** basis sets. The disrotatory stationary point with two imaginary vibrational frequencies is associated ...

-
(GORDON BREACH SCI PUBL LTD, 1996)Structural investigations using X-ray diffraction on methacrylate and acrylate based polymers with different side-chain mesogenic units are presented. The measurements were carried out by means of diffractometers with one ...
-
(TAYLOR & FRANCIS LTD, 2003-05)The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements ...
