-
(2016)Here we report the use of pigments produced by UV-resistant Antarctic bacteria as photosensitizers in Dye Sensitized Solar Cells (DSSCs). Pigments were obtained from red and yellow colored psychrotolerant bacteria isolated ...
-
(SOC BIOLGIA CHILE, 2007)Diabetic nephropathy (DN) is one of the major complications of type 2 diabetes and is associated with coronary disease. Nephrin, a protein mainly expressed in glomeruli, is decreased in DN and other kidney diseases. Since ...
-
(Colegio de Químico Farmacéutico de Chile, 1979)Estas dos especies arbóreas tienen grandes proyecciones económicas aparte de las tradicionales de madera y derivados. En nuestro país hay grandes extensiones de terrenos plantados con Pino y con Eucaliptus globulus, no ...
-
(MDPI, 2021)Alzheimer’s disease (AD), considered a common type of dementia, is mainly characterized by a progressive loss of memory and cognitive functions. Although its cause is multifactorial, it has been associated with the ...

(1996)(2'E, 6'E, 10'E, 14'E)-2-(8',9'-dione-3', 7', 11', 15'-tetramethylhexadeca-2', 6', 10', 14'-tetraenyl)-6-Methyl-1,4-benzoquinone, (2'E, 6'E, 10'E, 14'E)-2-(8'-one, 15'-formyl-3', 7', 11', trimethylhexadeca-2', 6', 10', ...
-
(ELSEVIER SCIENCE INC, 2008-05)In the search for new therapeutic tools against Chagas’ disease (American Trypanosomiasis) two series of new platinum(II) complexes with bioactive 5-nitrofuryl containing thiosemicarbazones as ligands were synthesized, ...
-
(2009)Eight new platinum(II) complexes with 3-(5-nitrofuryl)acroleine thiosemicarbazones showing anti-trypanosomal activity were synthesized, characterized and in vitro evaluated. Most of the complexes showed IC50 values in the ...
-
(ELSEVIER SCIENCE INC, 2008-04)Background: Increased oxidative stress, a common feature in chronic heart failure, has been associated with inflammation, endothelial dysfunction, and extracellular matrix degradation. Statins have known anti-inflammatory ...
-
(1988)The enthalpies of the reaction between glutathione and amoxycillin have been measured directly using a flow microcalorimeter. Comparative results are obtained by using an ac polarographic method previously developed in our ...
-
(INST ORGANIC CHEM AND BIOCHEM, ACAD SCI CZECH REPUBLIC, 1991-12)Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate ...

(1980)
-
Polarographic behaviour and determination of nitrofurantoin, chloramphenicol and related compounds (1984)The polarographic behaviour of nitrofurantoin and chloramphenicol have been studied in pyridine - formic acid buffer and tetramethylammonium chloride solution at pH 4.3. The E<inf>1/2</inf> versus pH and iym ...
-
(1994)A polarographic method for the determination of ranitidine is described, based on the reduction of the nitro group at a dropping-mercury electrode. The proposed method permits the drug to be determined, without any prior ...
-
(1991)A preconcentration method based on the adsorption on activated carbon of a binary complex of copper(I) with 2,2’-biquinoline, and subsequent polarographic determination of microamounts of copper has been developed. The ...
-
(Marcel Dekker, 1991)A preconcentration method based on the adsorption on activated carbon of a binary complex of copper(I) with 2,2¡-boquinoline, and subsequent polarographic determination of microamounts of copper has been developed. The ...
-
(Elsevier B.V., 1996)Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...
-
(Royal Society of Chemistry, 1987)In pyridine - formic acid buffer and tetramethylammonium chloride solution over the pH range 0-8.5, nitrofurazone, furazolidone and other nitrofuran derivatives are reduced in a six-electron process, giving rise to a well ...
-
(WILEY-V C H VERLAG GMBH, 2001-07)Megazol (2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1,3,4-thiadiazol, CAS 19622-55-0), a highly active compound used against several of Trypanosoma cruzi, the causative agent of Chagas disease, is electrochemically studied ...
-
(AMER PHARMACEUTICAL ASSN, 1990)Nifurtimox is polarographically reducible over the whole pH range, the nitro group being reduced to the hydroxylamine group in a 4ē process and subsequently the amine being formed in a 2ē process at a pH value below 4. The ...
-
(1992)Nimodipine, a calcium antagonist belonging to the dihydropyridine family, produces a well‐defined polarographic peak due to the four‐electron reduction of the nitro group. This peak was used to track the photodecomposition ...
