Effect of MnSOD (E. coli) on the relaxation caused by sodium nitroprusside on isolated rat renal artery / Efekat MnSOD (E. coli) Na relaksaciju izolovane renalne arterije pacova izazvanu natrijum-nitro-prusidom
(Serbian Chemical Society, 2004)
In this study themolecular foundation of nitric oxide induced relaxation of arteries, with or without endothelium, of normotensive and spontanously hypertensive ratswas re-examined. With this purpose in mind, the effects ...
7, 8, 15, 16-Tetraoxa-dispiro [5. 2. 5. 2]hexadecane-3-carboxylic acid derivatives and their antimalarial activity / Antimalarijska aktivnost derivata 7,8,15,16-tetraoksa-dispiro5.2.5.2heksadekan-3-karboksilne kiseline
(Serbian Chemical Society, 2004)
Several C2 symmetrical mixed tetraoxanes were prepared starting from a gemdihydroperoxide and a ketone. The obtained tetraoxanes showed pronounced antimalarial activity against P. falciparum chloroquine resistant W2 and ...
Stereoselective synthesis of α-hydroxy-β-amino acids: The chiral pool approach / Stereoselektivne sinteze α-hidroksi-β-aminokiselina iz prirodnih hiralnih prekursora
(Serbian Chemical Society, 2004)
A method for the stereoselective homologation of -amino acids into syn-α-hydroxy-β-amino acids is described, based on the conversion of stereoisomeric cyanohydrins into trans-oxazolines. The synthetic potential of the ...
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, ...
The synthesis and preliminary pharmacological evaluation of the racemic cis and trans 3-alkylfentanyl analogues / Sinteza i preliminarni farmakološki testovi recemskih cis i trans 3-alkilanaloga fentanila
(Serbian Chemical Soc, Belgrade, 2004)
A general five step method for the synthesis of 3-alkylfentanyl analogues (i.e. cis and trans 3-alkyl-4-anilidopiperidines 6.1-6.6) has been developed, The starting N-phenethyl-4-piperidone 1 was first converted into the ...
Electrochemistry of active chromium, part IV: Dissolution of chromium in deaerated sulfuric acid / Elektrohemija aktivnog hroma, deo IV - rastvaranje hroma u deaeriranom vodenom rastvoru sumporne kiseline
(Serbian Chemical Society, 2004)
Chromium dissolution in aqueous sulfuric acid solutions in the pH range 0.5 –3 was studied electrochemically by the potentiostatic or very slow potentiodynamic method, and by the analyses of the Cr ion concentrations in ...
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 ...
Thionation of N-methyl- and N-unsubstituted thiazolidine enaminones / Tionovanje n-metil- i n-nesupstituisanih tiazolidinonskih enaminona
(Serbian Chemical Society, 2004)
The potential of directional non-bonded 1,5-type S···O interactions to initiate the incipient stage of an in situ rearrangement of N-unsubstituted thiazolidine enaminones to functionalized 1,2-dithioles has been demonstrated. ...
