Metal ligand aromatic cation-pi interactions
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
Cation-pi interactions are important noncovalent bonding forces. This review covers a special type of cation-pi interactions, the metal ligand aromatic cation-pi (MLACpi) interaction, where ligands that are coordinated to ...
Synthesis of scopin acetate and 6,7-didehydrohyoscyamin. Intramolecular phenylsulfenylation of a nonactivated methylene group of ethyl N-demethyl-3-O-(phenylthio)tropine-N-carboxylate
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
The synthesis of scopin acetate (6b) and 6,7-didehydrohyoscyamine (17) was achieved by using tropine (5) as the starting compound. Formal (phenylthio)-radical transfer to the nonactivated 6-position of ethyl N-demethyl-3 ...
Modifications of fullerenes extractions and chromatographies with different solvents
(Taylor & Francis Inc, Philadelphia, 2003)
In the Bucky System II, based on electrical arc method, carbon soot was produced. Fullerenes C-60 and C-70 were Soxhlet extracted from the collected soot samples with toluene, chlorobenzene and with both of them successively, ...
Synthesis, characterization, interaction with DNA and cytotoxicity of the new potential antitumour drug cis-K[Ru(eddp)Cl-2]
(Elsevier Science Inc, New York, 2003)
The new potential antitumour soluble drug K[Ru(eddp)Cl-2].3H(2)O, (eddp = ethylenediamine-N,N'-di-3-propionate) has been isolated and characterized. The analysis of the interaction of this complex with pBR322 plasmid DNA ...
Partial purification and characterization of midgut leucyl aminopeptidase of Morimus funereus (Coleoptera : Cerambycidae) larvae
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Exopeptidases of Morimus funereus larvae were partially purified and characterized. Specific leucyl aminopeptidase (LAP) activity was increased eight-fold by gel filtration of the crude midgut extract. The partially purified ...
Acute exposure to higher ambient temperature potentiates cataleptic and hyperthermic effects of fentanyl in female rats
(Elsevier Science Bv, Amsterdam, 2003)
A novel and efficient 4-oxothiazolidine-1,2-dithiole rearrangement induced by Lawesson's reagent
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Functionalized 1,2-dithioles have been synthesized by a ring opening-closing process of 5-substituted- and 5-unsubstituted-2-alkylidene-4-oxothiazolidines with Lawesson's reagent. The C-13 NMR data confirmed the meso-ionic ...
Antimalarial and antiproliferative evaluation of bis-steroidal tetraoxanes
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Several cis and trans bis-steroidal 1,2,4,5-tetraoxanes possessing amide terminus were synthesised and evaluated as antimalarials and antiproliferatives. The compounds exhibited submicromolar antimalarial activity against ...
Crystal structure of bis[acetone-1-naphthoylhydrazinato(-1)]copper(II) and investigations of intermolecular interactions
(Wiley-V C H Verlag Gmbh, Weinheim, 2003)
In the crystal structure of the bis (acetone-1-naphthoylhydrazinato)copper(II) complex there are interactions of neighbouring molecules via naphthyl groups; the naphthyl group of one molecule interacts with the copper ...
Regioselective free radical phenylsulfenation of a non-activated delta-carbon atom by the photolysis of alkyl benzenesulfenate
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A regioselective free radical introduction of a phenylthio group onto a non-activated delta-carbon atom was achieved by photolysis of alkyl benzenesulfenates in the presence of hexabutylditin, and delta-phenylthio alcohols ...
