-
(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 ...

-
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 ...
-
(1990)The exposure of drugs to light produces photodecomposition processes in several cases: the drugs undergo important chemical changes with a parallel change in their activities or potencies and generally with a loss of their ...
-
(Sociedad Chilena de Cardilología y Cirugía Cardiovascular, 2005)Los polimorfismos de los receptores β Adrenérgicos (AR) influencian el grado de actividad del receptor. Los βAR tienen un rol importante en la regulación de la contractilidad y podrían tener implicancias en el riesgo de ...
-
(2006)The synthesis, characterization and electrochemistry of a novel nanocomposite based on the co-intercalation of lithium and poly(acrylonitrile) (PAN) in molybdenum disulfide [Li0.6MoS2(PAN) 1.2·0.5H2O] is described. The ...
-
(Taylor and Francis Inc., 1998)Interpolymer complex (IC) formation between poly(ethylene-co-maleic acid) and poly(4-vinylpiridine) (P4VPy) has been observed and characterized. Data from viscosity, infrared spectroscopy and thermogravimetric analysis ...
-
(0887-624X, 2005-10-15)The free-radical copolymerization of N-phenylmaleimide (N-PhMI) with acrylic acid was studied in the range of 25-75 mol % in the feed. The interactions of these copolymers with Cu(H) and Co(H) ions were investigated as a ...
