Palladium(II) complexes with R2edda-derived ligands. Part II. Synthesis, characterization and in vitro antitumoral studies of R2eddip esters and palladium(II) complexes
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2009)
New R2eddip-type esters (R = cyclopentyl, L3·2HCl 1.5H2O; cyclohexyl, L4·2HCl·H2O) and corresponding palladium(II) complexes, [PdCl2L3] (3) and [PdCl2L4]·H2O (4), as well as [PdCl2L2] (2; L2 diisobutyl ester of eddip) were ...
One-step conversion of ketones to conjugated acids using bromoform
(Synthetic Communications, 2009)
Phase-transfer-catalyzed (PTC) reactions of ketones with bromoform and aqueous lithium hydroxide in alcoholic solvent result in the formation of ,-unsaturated carboxylic acids. The reaction was performed at room temperature ...
Estrone derived steroidal diepoxide: Biologically active compound and precursor of a stable steroidal A,B-spiro system
(Elsevier Science Inc, New York, 2009)
A simple approach to a stable steroidal estrone derived A,B-spiro system is reported. Treatment of estrone derived A-ring diepoxyalcohol with the Ac2O-TMSOTf system at the ambient temperature led to acetylation, while at ...
Mixed steroidal tetraoxanes induce apoptotic cell death in tumor cells
(Investigational New Drugs, 2009)
In this study we investigated the antiproliferative activity of six mixed steroidal tetraoxanes against various tumor cell lines, the toxicity against normal peripheral blood mononuclear cells (PBMC), and the mode of HeLa ...
Similar bifidogenic effects of the infant formulae with added inuline and breast feeding on gut microflora
(Elsevier, 2009)
The purpose of this study was to determine if there is and what are the differences in the bifidogenic effects and gut microflora of breast-fed and formula-fed newborns (younger than 6 months and
children age from 6 to ...
