Ring closing metathesis/fragmentation route to (Z)-configured medium ring cycloalkenes. Total synthesis of (+/-)-periplanone C
(Amer Chemical Soc, Washington, 2006)
The combination of ring closing metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium ring cycloalkenes. The fragmentation step can be effected under anionic or radical conditions. The ...
Acid-base equilibria of 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid and its labeling with technetium-99m / Kiselinsko-bazne ravnoteže 2,4-dijod-6-metilfenilkarbamoilmetil iminodisirćetne kiseline i obeležavanje tehnecijumom-99m
(Srpsko hemijsko društvo, Beograd, 2006)
The acid-base equilibria of a novel hepatobiliary imaging agent, 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid (DIIODIDA) were studied. The potentiometrically determined acidity constants of the second ...
EDXRF spectrometry determination of tungsten in tobacco plants after antiviral treatment with 12-tungstophosphoric acid and its compounds
(Elsevier Science BV, Amsterdam, 2006)
In this study, we have developed a sensitive, rapid and simple procedure for the energy dispersive X-ray fluorescence (EDXRF) spectrometry measurement of tungsten in tobacco plant parts. Only 0.1 g of dried plant material ...
Safe use of herbal drugs during pregnancy and lactation / Bezbedna primena biljnih lekova u trudnoći i tokom perioda dojenja
(Savez farmaceutskih udruženja Srbije, Beograd, 2006)
Pregnancy is very specific period in which special warnings in drug use, including herbal drugs are recommended. This is related on period of lactation, too, since all drugs distributed and excreted into human milk potentially ...
New evidence of transient complex oscillations in a closed, well-stirred belousov-zhabotinsky system / Novozabeležene tranzijentne kompleksne oscilacije u zatvorenom belousov-žabotinski reakcionom sistemu sa dobrim mešanjem
(Srpsko hemijsko društvo, Beograd, 2006)
Some new experimental evidence of complex irregular oscillations in the Belousov-Zhabotinsky reaction realized in a batch reactor is presented. The results were obtained under relatively low cerium and malonic acid ...
Development and validation of liquid chromatography method for the separation of valdecoxib and its SC-77852 impurity
(Taylor & Francis Inc, Philadelphia, 2006)
A reversed-phase liquid chromatography method has been developed for the separation of valdecoxib and impurity SC-77852. The best results were achieved using a mobile phase-methanol: 1% water solution TEA (52 : 48 v/v), ...
Effect of supplemental magnesium on the kidney levels of cadmium, zinc, and copper of mice exposed to toxic levels of cadmium
(Humana Press Inc, Totowa, 2006)
In this report, we present the results of our investigations on the effect of Mg pretreatment on Cd and bioelements (Cu and Zn) contents in kidney of mice exposed to acute and subacute Cd intoxication. Acute intoxication ...
Interaction of quinapril anion with cationic surfactant micelles of cetyltrimethylammonium bromide
(Academic Press Inc Elsevier Science, San Diego, 2006)
In this study, the interaction of the anion of quinapril (QUIN), angiotensin converting enzyme (ACE) inhibitor, with cationic surfactant cetyltrimethylammonium bromide (CTAB) was investigated. The effect of cationic micelles ...
Association of C-reactive protein with the presence and extent of angiographically verified coronary artery disease
(Tohoku Univ Medical Press, Sendai, 2006)
Prospective studies have demonstrated that markers of inflammation, such as high-sensitivity C-reactive protein (hsCRP) and fibrinogen, predict future cardiovascular disease risk. However, the association between the hsCRP ...
Synthesis, characterization, and biological activity of amino acid derivatives of the heteropolytungstophosphoric acid
(Springer Wien, Wien, 2006)
Compounds of phosphotungstic acid (WPA) containing the amino acids alanine (WPA-Ala) or glycine (WPA-Gly) as counter cations were synthesized and characterized by elemental analysis, thermal analysis, and IR spectroscopy. ...
