    Notes: Using a flourescence-detected ethidium displacement assay, the calf thymus DNA complexation properties of 27 mono-, di-, tri-, tetra- and hexacationic polyamines were determined. The DNA-binding affinity of these polyamine compounds increased with increasing cationic charge on the polyamine. Although most of the compounds exhibited no base pair binding selectivity, two of the tricationic polyamines possessing additional neutral amine groups exhibited approximately tenfold GC binding selectivities.

    Notes: An enantioselective gas chromatographic method has been developed and validated for the determination of the plasma concentration of the enantiomers of the anticancer drug ifosfamide (IFF). In this approach, the IFF enantiomers are separated from the plasma matrix by solid phase extraction, chromatographically resolved by gas chromatography on a chiral stationary phase, and detected by mass selective detection using selective ion monitoring. The assay has been validated for routine clinical and pharmacokinetic use and has a limit of detection in plasma of 250 ng/ml of each isomer.

    Description / Table of Contents: Synthese eines Carbaanalogen des S-Palmitoyl-coenzyms A, Heptadecan-2-onyldesthio-CoA und von S-Heptadecyl-CoA, zwei wirksamen Inhibitoren der Citratsynthase und der Carnitin-PalmitoyltransferaseDie Synthesen der langkettigen Alkylderivate1 und2 des Coenzyms A werden beschrieben. Heptadecan-2-onlydesthio-CoA(1), ein Carbaanaloges von S-Palmitoyl-CoA, wird zusammen mit seinem isomeren 2′-Phosphat11 durch Kondensation von Adenosin-2′,3′-cyclophosphat-5′-phosphomorpholidat(10) mit dcm in situ aus8b erzeugten Palmitoyldesthio-carba-pantethein-phosphat(8a) erhalten. Der cyclische Phosphodiester, der dabei entsteht, ergibt bei der Hydrolyse ein Gemisch von 3′- und 2′-Phosphat1 bzw.11. S-Heptadecyl-CoA(2) wird durch Alkylierung von CoA mit Heptadecyliodid hergestellt. Sowohl das Isomerengemisch (1 +11) als auch Verbindung2 zeigen Merkmale einer nicht kompetkiven Hemmung der Citratsynthase (K1 = 6.0-7.5 · 10-6 mol/l bzw. 1.0-1.5 · 10-6 mol/l) und einer kompetitiven Hemmung der Carnitin-Palmitoyltransferase (K1 = 1.35 · 10-6 mol/l bzw. 3.34 · 10-6 mol/l).
    Notes: The syntheses of long chain alkyl-coenzyme A derivatives1 and2 are reported. Heptadecan-2-onyldethio-CoA(1) a carba analog of S-palmitoyl-CoA is obtained along with its 2′-phosphate isomer11 by the condensation of adenosine 2′,3′-cyclic phosphate-5′-phosphoromorpholidate(10) with the in situ generated palmitoyldethio-carbapantetheine phosphate(8a). The cyclic phosphodiester produced upon hydrolysis yields a mixture of 3′-phosphate1 and 2′-phosphate 11. S-Heptadecyl-CoA(2) is obtained from the alkylation of CoA with heptadecyl iodide. Both the isomeric mixture (1 +11) and compound2 exhibit characteristics of non-competitive inhibition with citrate synthase (K1 = 6.0-7.5 · 10-6 mol/I and 1.0-1.5 · 10-6 mol/l, respectively) and characteristics of competitive inhibition with carnitine palmitoyltransferase (K1 = 1.35 · 10-6mol/l and 3.34 · 10-6 mol/l, respectively).

    Description / Table of Contents: Synthese des carbaanalogen S-Acetyl-coenzym A,Acetonyldesthio-coenzym A; einem wirksamen Inhibitor der CitratsynthaseAcetonyldesthio-coenzym A (1) im Gemisch mit dem 2′-Phosphoisomeren 10 wurde vom Glykolketal des 5-Amino-2-pentanons (4) ausgehend durch Kupplung mit N-Benzyloxycarbonyl-β-alanin zu 5, Verknüpfen des deblockierten Alethein-Analogen 5 mit D-2-Hydroxy-3,3-dimethyl-4-butyrolacton zum Pantethein-Analogen 6, dessen Veresterung an der 4′-Hydroxygruppe mit Phosphorsäure zu 7 und Verknüpfung von 7 mit Adenosin-2′-3′-cyclophosphat-5′-phosphorsäuremorpholid erhalten. Das Gemisch der Isomeren 1 und 10 zeigt an der Citratsynthase (S-Acetyl-CoA + Oxalacetat) starke kompetitive Hemmung mit Ki = 13.2 μmol/l.
    Notes: Acetonyldethio coenzyme A (1) together with its 2′-phospho isomer 10 was obtained by the following reaction sequence: coupling of the glycol ketal 4 of 5-amino-2-pentanone with N-benzyloxycarbonyl-β-alanine, fusion of the deblocked aletheine analog 5 with the lactone of D-2,4-dihydroxy-3,3-dimethylbutyric acid to yield the pantetheine analog 6, which was phosphorylated at the 4′-hydroxy group to form 7, and then condensation with adenosine 2′,3′-cyclic phosphate 5′-phosphoric morpholide. The isomeric mixture exhibited strong competitive inhibition of citrate synthase (S-acetyl CoA + oxaloacetate), Ki being 13.2 μmol/l.

    Notes: Tri(n-butyl)tin (TBT) concentrations were determined in sediments and selected shellfish from Suva Harbour, Fiji. Sediments in the immediate vicinity of foreshore slipways and boatyards were exceedingly contaminated, with a maximum observed level of 38μ g-1 TBT-Sn. Concentrations were much lower in surficial sediments from commercial docks and yacht mooring areas, namely 16-83 ng g-1 TBT-Sn. Mangrove oysters (Crassostrea mordax), gastropods (Thais mancinella), and bivalves (Anadara scapha) were found to have accumulated TBT. Concentrations as high as 3180 ng g-1 TBT-Sn were found in mangrove oysters. With respect to the mangrove oyster, its widespread distribution, abundance and proclivity to accumulate TBT suggest that it is likely to be the best bioindicator species of TBT contamination in Fijian coastal waters.
