Synthesis of 5-azaandrostane-3β,17β-diol protected at the 17β-hydroxyl group
(Serbian Chemical Society, 2004)
In the present paper, the preparation of 3β-hydroxy-17β-dimethyl- tert-butylsilyloxy-5-azaandrostane (15) in fourteen steps is described. B-nor-17-oxoandrost-5-en-3β-yl acetate (1) 1,2 was used as the starting material, ...
Tetrahydrofuran-type sesquiterpenes from Artemisia lobelii All. var. canescens (DC.) Briqu. and Artemisia lobelii All. var. biasolettiana (Vis.) K. Maly
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Covalent glycoinositolphospholipid (GPI) binding to hemoglobin is associated with insulin-activation of erythrocyte membrane protease / Kovalentno vezivanje glikoinozitolfosfolipida (GPI) za hemoglobin pod dejstvom insulina praćeno je aktiviranjem proteaze iz membrane eritrocita
(Serbian Chemical Soc, Belgrade, 2004)
Recently, it was demonstrated that prolonged hyperinsulinism associated with hypoglycemia, both in vivo and in vitro, caused covalent glycoinositolphospholipid (GPI) binding to the C termini of both hemoglobin beta-chains, ...
Stereoselective synthesis of (-)-cytoxazone and (+)-epi-cytoxazone
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Optically pure (-)-cytoxazone was synthesized, starting from methyl p-methoxycinnamate, in six steps and in 31%, overall yield. The required anti-aminoalcohol configuration was established by combining Sharpless asymmetric ...
Guaianolides from two subspecies of Amphoricarpos neumayeri from Montenegro
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Quantitative H-1 NMR measurements revealed Delta(11(13)) sesquiterpene gamma-lactones as the main constituents (greater than or equal to 1% per weight of dried plant material) in the crude extracts of the aerial parts of ...
Sesquiterpene lactones from Cicerbita alpina
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
The roots of Cicerbita alpina (L.) Wallr. were collected from Mt. Komovi, Montenegro.
Isoforms of leucyl-aminopeptidase of Cerambyx cerdo (Coleoptera, Cerambycidae) larvae

Modeling of adsorber/desorber/catalytic reactor system for ethylene oxide removal / Modelovanje sistema adsorber/desorber/katalitički reaktor za uklanjanje etilen oksida
(Serbian Chemical Society, 2004)
The removal of ethylene oxide (EtO) in a combined system adsorber desorber/catalytic reactor has been investigated. The combined system was a modified draft tube spouted bed reactor loaded with Pt/Al2O3 catalyst. The annular ...
Electrostatic surface potential calculation on several new halogenated benzimidazole-like dopaminergic ligands
(Wiley-VCH Verlag, 2004)
We examined the effects of the electron density distribution (electrostatic surface potential; ESP) of several new benzimidazole-type ligands on their binding affinity for the D 1 and D 2 dopamine receptors (DAR). Receptors ...
