Cytotoxic constituents of Achillea clavennae from Montenegro
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Examination of the aerial parts of Achillea clavennae afforded eight guaianolides (1-8), three bisabolenes (9 11), four flavonols (12-15), sesamin (lignan) and isofraxidin (coumarin). The structures of the new compounds ...
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 ...
Synthesis of some steroidal oximes, lactams, thiolactams and their antitumor activities
(Elsevier, 2007)
The antiproliferative activity of previously synthesized (Z)-cholest-4-en-6-one oxime (1), (E)-cholest-4-en-6-one oxime (2), 7-aza-B-homocholest-4-en-6-one (3) and 6-aza-B-homocholest-4-en-7-one (4) and newly synthesized ...
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 ...
Partial purification and characterization of midgut leucyl aminopeptidase of Morimus funereus (Coleoptera : Cerambycidae) larvae
(Oxford : Pergamon-Elsevier Science Ltd, 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 ...
Allozyme polymorphism of Mdh and alpha-Gpdh in Ixodes ricinus populations: comparison of borreliae-infected and uninfected ticks
(Springer, Dordrecht, 2006)
Ixodes ricinus Linnaeus (Acari: Ixodidae) ticks are vectors of numerous infectious diseases in humans and animals. The allozyme variability of MDH and alpha-Gpdh was detected by native polyacrylamide gel electrophoresis ...
The influence of silver content on antimicrobial activity and color of cotton fabrics functionalized with Ag nanoparticles
(Elsevier, 2009)
The aim of this study was to examine the antimicrobial efficiency and color changes of cotton fabrics
loaded with colloidal silver nanoparticles which were synthesized without using any stabilizer. The influence
of ...
Detection and quantification of leucyl arninopeptidase after native electrophoresis using leucine-p-nitroanilide
(Wiley-V C H Verlag Gmbh, Weinheim, 2005)
A general method for detecting leucyl aminopeptidase activity after native polyacrylamide gel electrophoresis (PAGE) in situ is described. The method is based on diazotization of p-nitroaniline, liberated in the polyacrylamide ...
