    Notes: Summary Fructose-1,6-bisphosphatase is a key enzyme in gluconeogenesis and the FBP1 gene is not transcribed during growth with glucose. Genetic analysis indicated a positive regulation of FBP1 expression after exhaustion of glucose. By linker-deletion analysis, two upstream activation sites (UAS1 and UAS2) were localized and the respective UAS-binding factors (DAP I and DAP II for derepression activating protein) were identified by gel retardation. UAS1 and UAS2 span about 30 bp each, and are separated by approximately 30 bp. Both UAS sites act synergistically. Although UAS1 showed some similarities to the DNA-binding consensus for the general yeast activator Rap1, competition experiments and DEAE-chromatography proved that DAP I and Rap1 correspond to different proteins. Gel retardation by DAP I depended on carbon sources and did not occur in cells growing logarithmically with glucose, whereas a strong retardation signal was obtained with ethanol-grown cells. The present results suggest that DAP I and DAP II are the final regulatory elements for glucose derepression.

    Description / Table of Contents: Branched and Chain-extended Sugars, XXX.  -  Diastereoselective Synthesis of L-glycero-D-manno-Heptose, a Constituent of the Inner Core Region of LipopolysaccharidesReaction of 2,3;5,6-di-O-isopropylidene-D-mannofuranose (1) with 2-lithio-1,3-dithiane affords diastereoselectively the 3,4;6,7-di-O-isopropylidene-D-glycero-D-galacto-heptose trimethylene dithioacetal (3). Conversion of compound 3 by a sequence of steps gives the tri-O-isopropylidene-D-glycero-D-galacto-heptit 16 which is oxidized with 1,1′-(azodicarbonyl)-dipiperidine to give the tri-O-isopropylidene-L-glycero-D-manno-heptose 17. Finally, compound 17 is transferred via the acetate 19 into the L-glycero-D-manno-heptopyranose 18.

Nach Umwandlung von 3 über eine Reihe von Zwischenstufen zum Tri-O-isopropyliden-D-glycero-D-galacto-heptit 16 läßt sich dieser mit 1,1′-(Azodicarbonyl)dipiperidin zur Tri-O-isopropyliden-L-glycero-D-manno-heptose 17 oxidieren. Hieraus ist über das Acetat 19 die freie L-glycero-D-manno-heptopyranose 18 zu gewinnen.

    Bausteine von Oligosacchariden, LXXVIII. Synthese von KDO-haltigen Lipoid-A-Analoga (1987)

    Description / Table of Contents: Building Units of Oligosaccharides, LXXVIII. - Synthesis of KDO-Containing Lipid A AnaloguesThe non-neighbouring group supported glycosidation of 12 with the suitably protected glycosyl bromide 9 of 2-azido-2-deoxy-D-glucose leads - in the presence of a heterogeneous silver catalyst - to the formation of the β-(1→6)-glycosidically linked disaccharide 14. It consists of two 2-azido-2-deoxy-D-glucose units. Partial deblocking of 14 furnishes 15. On glycosidation with KDO bromide this compound yields the trisaccharide 16, which contains a KDO unit in an α-(2→6) ketosidic bond. Reduction of the two azido groups followed by amidation with (R)-3-hydroxymyristic acid and further deblocking generates the trisaccharide α-KDO-(2→6)-β-D-GlcA-(1→6)-D-GlcA 20 with two 3-hydroxy fatty acid residues in an amidic linkage.
    Notes: Die Umsetzung des Pyranosylbromids 9 der 2-Azido-2-desoxy-D-glucose mit dem Akzeptor 12 führt bei Gegenwart eines heterogenen Silberkatalysators ohne Nachbargruppenbeteiligung unter Inversion zum β-(1→6)-glycosidisch verknüpften Disaccharid 14 aus zwei 2-Azido-2-desoxy-D-glucose-Einheiten. Nach partieller Entblockierung zu 15 ist die Anknüpfung eines KDO-Restes unter Bildung einer α-(2→6)-ketosidischen Bindung zum Trisaccharid 16 möglich. Nach Reduktion der Azidogruppen und Anknüpfung von (R)-3-Hydroxymyristinsäure-Resten gelangt man nach Entblockierung zum Trisaccharid α-KDO-(2→6)-β-D-GlcA-(1→6)-D-GlcA 20, das amidartig zwei 3-Hydroxyfettsäure-Reste gebunden enthält.

    Notes: A specific and sensitive gas chromatographic/mass spectrometric method was developed and validated for the determination of the antidepressant levoprotiline in blood, plasma and urine and the simultaneous determination of levoprotiline and its desmethyl metabolite in urine. Deuterium-labelled analogues were used as internal standards. The compounds were isolated from the biological fluids by liquid-liquid extraction under basic conditions. Following derivatization with perfluoropropionic anhydride, the samples were analysed by capillary column gas chroma-tography/electron impact mass spectrometry with selected ion monitoring. The analysis of spiked samples demonstrated the high accuracy and precision of the method. Blood concentrations of levoprotiline down to 0.7 nmol I-1 (1 ml used for analysis) could be quantified with a coefficient of variation of 10% or less. The method is suitable for use in pharmacokinetic and bioavailability studies of levoprotiline in humans.
