Lipophilicity of some guaianolides isolated from two endemic subspecies of Amphoricarpos neumayeri (Asteraceae) from Montenegro
(Biomedical Chromatography, 2009)
In this study 10 guaianolide-type sesquiterpene γ-lactones named amphoricarpolides, isolated from the aerial parts of two endemic subspecies of Amphoricarpos neumayeri (ssp. neumayeri and ssp. murbeckii Bosnjak), were ...
Synthesis and biological evaluation of some 17-picolyl and 17-picolinylidene androst-5-ene derivatives
(Elsevier, 2007)
Starting from dehydroepiandrosterone (1) 17-picolyl (2), 17-picolinylidene (7), 17-picolinylidene-16-one (10 and 11), and 17-picolyl-16-one (15) derivatives of androst-5-ene were synthesized in one, two, four and five steps ...
Effect of cooling rate on the microstructure and magnetic properties of melt spun Nd-Fe-B alloys
(Elsevier, 2003)
The results of X-ray analysis, Mossbauer spectroscopy and magnetic measurement for melt-spun Nd-Fe-B with low content Nd obtained by optimal selected cooling rate and heat treatment are presented to bring some new information ...
Leucine aminopeptidase from Streptomyces hygroscopicus is controlled by a low molecular weight inhibitor
(Society of Fermentation and Bioengineering, 2002)
In culture filtrate of Streptomyces hygroscopicus a producer of polyketide antibiotics, a leucine aminopeptidase and its autogenous inhibitor were detected. The leucine aminopeptidase was purified 4573-fold with yield of ...
Synthesis, characterization and antitumor activity of novel N-substituted α-amino acids containing ferrocenyl pyrazole-moiety
(Journal of Organometallic Chemistry, 2009)
A series of new N-[(3-ferrocenyl-1-phenylpyrazol-4-yl)methyl] α-amino acids were prepared and characterized by a range of spectroscopic techniques and cyclic voltammetry. The in vitro antitumor activity of all synthesized ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Elsevier, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Synthesis, biology, and modeling of a C-4 carbonyl C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
A C,D-seco-paclitaxel derivative 26 was prepared from taxine and tested for biological activity. Chemical reactivity of the seco-compounds proved to be substantially modified, with respects to taxoids. The corresponding ...
Synthesis, biological evaluation, and modeling of a C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
A C,D-seco-paclitaxel derivative 12 was prepared and tested for biological activity. The key step in the synthesis was a free radical fragmentation of the bicyclic tertiary alcohol 7 under the conditions of the hypobromite ...
Iron catalyzed conversion of NO into nitrosonium (NO+) and nitroxyl (HNO/NO-) species
(Elsevier, 2004)
The conversion of NO into its congeners, nitrosonium (NO+) and nitroxyl (HNO/NO-) species, has important consequences in NO metabolism. Dinitrosyl iron complex (DNIC) combined with thiol ligands was shown to catalyze the ...
Antitumor effects of a natural anthracycline analog (Aloin) involve altered activity of antioxidant enzymes in HeLaS3 cells
(Taylor & Francis Inc, Philadelphia, 2007)
The anti proliferative and cytotoxic potential of the natural anthracycline aloin from Aloe vera was tested on human uterine carcinoma HeLaS3 cells. Aloin showed a pronounced antiproliferative effect at physiological ...
