(SPRINGER/PLENUM PUBLISHERS, 2010-10)The formation of the complexes of galangin (GAL) with native β-cyclodextrin (βCD), and with its substituted counterparts such as dimethyl-βCD (DMβCD) and hydroxypropyl-βCD (HPβCD), was studied by fluorescence spectra in ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-05-15)A series of indazole N-oxide derivatives have been synthesized and their antichagasic and leishmanocidal properties studied. 3-Cyano-2-(4-iodophenyl)-2H-indazole N-1-oxide exhibited interesting antichagasic activity on the ...
-
(Bentham Science Publishers Ltd., 2008)In order to get insight into the trypanocidal mechanism of action of a series of 5-nitrofuryl containing thiosemicarbazones some studies related to their bioreduction were performed. Electron spin resonance spectra of ...
-
(JOHN WILEY & SONS LTD, 2007-01)Chlorophenylmaleimide (Cl-PhMI) and N-maleoylglycine (N-MG) with beta-methylhydrogen itaconate (beta-MHI) were copolymerized by radical polymerization, and their metal ion retention capacity (MRC) and thermal behavior were ...

(JOHN WILEY & SONS INC, 2002-03-15)The electronic structures of complexes and one-dimensional metallomacrocycles with cyanide as bridged ligand, such as [MacM(CN)(2)](-) and [MacM(CN)](n) [Mac = phthalocyanine, tetrabenzoporphyrine; M = Co(III), Rh(III)] ...
-
(ELSEVIER, 2010)A new series of heteroaryl nitrones, 1–7, bearing furoxanyl and thiadiazolyl moieties, were evaluated for their free radical-trapping properties. The physicochemical characterization by electron paramagnetic resonance ...
-
(ROYAL SOC CHEMISTRY, 2012)In the search for new therapeutic tools against neglected diseases produced by trypanosomatid parasites, and particularly against African Trypanosomiasis, whose etiological agent is Trypanosoma brucei, organoruthenium ...
-
(ELSEVIER, 2006-11)Rhenium and ruthenium complexes of the type [(ReOCl2)-O-V(PPh3)L] and [(RuC2)-C-II(DMSO)(2)L], where L are 5-nitroftitylsemicarbazone derivatives, were prepared in an effort to obtain new anti-trypanosomal agents combining ...
-
(Bentham Science Publishers Ltd., 2017)Background: Nowadays, nitrones are the most used spin traps to characterize free radicals in biological systems due to the versatility and variety depending on the types of radicals to study and that the half-lives of the ...
-
(PERGAMON-ELSEVIER SCIENCE, 2000)This paper reports both the electrochemical characterization and the reactivity of the nitroso radical anion from nitrosobenzene with glutathione. The reduction of nitrosobenzene to the corresponding nitroso radical anion ...
