Isoforms of leucyl-aminopeptidase of Cerambyx cerdo (Coleoptera, Cerambycidae) larvae
(University of Belgrade, University of Novi Sad, 2004)
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
Ring-closing metathesis/fragmentation route to geometrically defined medium-ring cycloalkenes: Total synthesis of (+/-)-periplanone C
(American Chemical Society (ACS), 2004)
The combination of alkene metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium-ring cycloalkenes. The versatility of this method is demonstrated by the total synthesis of Periplanone C, a ...
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)
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, ...
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 ...
Modeling of the D2 dopamine receptor arylpiperazine binding site for 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4-arylpiperazines
(Wiley-VCH Verlag, 2004)
Docking of several 1-{2-[5-(1H-benzimidazole-2-thione)]ethyl}-4- and 1-benzylarylpiperazines to the D 2 dopamine receptor (DAR) was examined. The binding pocket of the D 2 DAR defined according to Teeter and DuRand [1] was ...

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 ...
A new type of slow-wave PBG microstrip structures
(Journal of Microwaves and Optoelectronics, 2004)
A new type of 1D slow-wave PBG microstrip structures is introduced. They have no etching in the ground plane and have a simple modification of the microstrip line. The basic cell is applied to three different structures. ...
