Square-planar copper(II) complexes with tetradentate amido-carboxylate ligands. Crystal structure of Na-2[Cu(obap)](2)center dot 2H(2)O. Strain analysis and spectral assignments of complexes
(Elsevier Science Sa, Lausanne, 2005)
Novel N-N-N-O-type of tetradentate ligands H(3)obap (H(3)obap = oxamido-N-aminopropyl-N'-benzoic acid) and H(3)maeb (H(3)maeb = malamido-N-aminoethyl-N'-benzoic acid) and the corresponding square-planar copper(H) complexes ...
The thermal stability of the external invertase isoforms from Saccharomyces cerevisiae correlates with the surface charge density
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2012)
Understanding the effect of surface charge on the stability of proteins is one prerequisite for "tailoring" proteins with increased thermal stability. Here, we investigated the origin of the altered thermal stability ...
Transglucosylation of hydroquinone catalysed by alpha-glucosidase from baker's yeast
(Elsevier Science Bv, Amsterdam, 2005)
Hydroquinone alpha-isomaltoside and hydroquinone alpha-glucoside were synthesized by transglucosylation in an aqueous system with baker's yeast alpha-glucosidase from hydroquinone and maltose as a glucosyl donor. Only one ...
Synthesis and water solubility of novel fullerene bisadduct derivatives
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
The synthesis of four classes of bisadduct derivatives of C-60 is reported. The solubility of the new compounds in aqueous solvents is enhanced and is among the highest ever reported for fullerene derivatives. ((C) Wiley-VCH ...
Geochemical characterization of the hydrous pyrolysis products from a recent cyanobacteria-dominated microbial mat.
(Univ Barcelona, Barcelona, 2016)
Hydrous pyrolysis experiments were performed on a recent microbial mat sample from Lagoa Vermelha, Brazil, to determine whether crude oil can be generated and expelled during artificial maturation of the Organic Matter ...
Antiproliferative activity and QSAR studies of a series of new 4-aminomethylidene derivatives of some pyrazol-5-ones
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Twenty five 4-aminomethylidene derivatives obtained from 3-phenyl-2-pyrazolin-5-one and 1,3-diphenyl-2-pyrazolin-5-one were synthesized and tested for their antiproliferative activity against human breast cancer MDA-MB-361 ...
Guaianolides from Centaurea nicolai: antifungal activity
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
A new guaianolide, 3-deacetyl-9-O-acetylsalograviolide A, along with four known closely related lactones, salograviolide A, 9-O-acetylsalograviolide A, kandavanolide and salograviolide B were detected in the aerial parts ...
New radical reactions of S-alkoxycarbonyl xanthates. Total synthesis of (+/-)-cinnamolide and (+/-)-metlhylenolactocin
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Irradiation with visible light of S-alkoxycarbonyl xanthates derived from various alcohols gives rise to alkoxycarbonyl radicals with bifurcate reactivity: loss of carbon dioxide leads to deoxygenated derivatives (i.e. ...
Microwave-hydrothermal synthesis of TiO2 and zirconium doped TiO2 adsorbents for removal of As(III) and As(V)
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-hydrothermal method was used for the synthesis of TiO2 and TiO2 doped with zirconium. The method was fast and simple and adsorbents were used for removal of As(III) and As(V) from aqueous solutions. The adsorbents ...
High-yield synthesis of substituted and unsubstituted pyridinium salts containing a 4-oxothiazolidine moiety
(Georg Thieme Verlag Kg, Stuttgart, 2008)
A new series of unsubstituted and substituted pyridinium salts bearing a 4-oxothiazolidinyl moiety has been prepared by an efficient rearrangement of 2-(I-bromoalkylidene)thiazolidin-4ones. The process is based on three ...
