    Notes: Summary The elimination of pindolol was studied in 32 patients suffering from various liver diseases, mainly acute hepatitis and hepatic cirrhosis. The total body clearance of antipyrine was measured simultaneously as a parameter of liver microsomal enzyme activity. The doses given were antipyrine 1000 mg orally and pindolol 3 mg i.v. Plasma samples were taken and urine was collected for up to 72 h for the measurement of drug concentrations. In addition, conventional biochemical laboratory tests were done. The total body clearance of antipyrine was compared with the pharmacokinetic parameters calculated for pindolol, and the results of the biochemical tests. No correlation was found between antipyrine clearance and the routine biochemical parameters in liver disease or with the total body clearance of pindolol. A significant correlation was seen with the nonrenal clearance of pindolol taken as representing its major metabolic degradation. Higher correlation coefficients were observed when two subgroups of patients with acute hepatitis and hepatic cirrhosis were separated. In some patients suffering from hepatic cirrhosis a higher urinary excretion of unchanged pindolol was observed as liver function become decompensated, a finding due to an unknown mechanism but based on intact renal function. In patients with acute hepatitis a much higher nonrenal clearance was found than in many other patients, which might be based on increased liver blood flow.

    Topics: Chemistry and Pharmacology
    Notes: Abstract The theorem of Hohenberg and Kohn is extended to subdomains of a bounded quantum system. It is shown that the ground state particle density of an arbitrary subdomain uniquely determines the ground state properties of this subdomain, of any other subdomain, and of the total domain of the system.

    Description / Table of Contents: Synthesis of Dimethyl-N-Chloroammonium Trifluoromethane Sulfonate ((CH3)2NClH+ CF3SO3-)The weak base dimethyl-N-chloroamine, (CH3)2NCl, reacts with trifluormethane sulfonic acid at -40 to -30°C to give dimethyl-N-chloroammonium trifluoromethane sulfonate (CH3)2NClH+CF3SO3-. The extremely hygroscopic salt decomposes upon melting at 107 to 108°C and thus is slightly more stable than the hydrogensulfate. Water or methanole liberate dimethyl-N-chloroamine from the salt. The salt is insoluble in ether and decomposes after dissolving in methylene chloride to give dimethylammonium trifluoromethane sulfonate (CH3)2NH2+CF3SO3-.
    Notes: Die schwache Base Dimethyl-N-Chloramin, (CH3)2NCl, reagiert mit Trifluormethansulfonsäure bei -40 bis -30°C unter Bildung von Dimethyl-N-Chlorammoniumtri-fluormethansulfonat ((CH3)2NCIH+CF3SO3-). Das sehr hygroskopische Salz schmilzt bei 107 bis 108°C unter Zersetzung und ist somit etwas stabiler als das Hydrogensulfat. Durch Wasser oder Methanol wird aus dem Salz Dimethyl-N-Chloramin freigesetzt. Das Salz ist unlöslich in Ether und zersetzt sich nach dem Auflösen in Methylenchlorid in Dimethylammoniumtrifluormethansulfonat (CH3)2NH2+CF3SO3-.

    Description / Table of Contents: Trimethylsilyl Derivatives of Vb-Elements. IV. Synthesis and Structure of Lithium Bis(trimethylsilyl)antimonide · DMETris(trimethylsilyl)stibine and methyllithium react in 1,2-dimethoxyethane (DME) to give tetramethylsilane and lithium bis(trimethylsilyl)antimonide · DME 1. The latter compound 1 crystallizes tetragonal in the acentric space group I42d; the unit cell dimensions determined at the temperature of data collection (-85°C) are: a = 1004.95(2); c = 3714.70(1) pm; Z = 8. The crystal structure determination (R = 0.030) shows the presence of screw-shaped macromolecules. The chains are built up by bis(trimethylsilyl)stibino groups and DME-coordinated lithium atoms in alternating sequence. They might be characterized by a Dornberger-Schiff symbol such as P(2)21(2) and are stacked according to rules derived by O'Keeffe and Andersson. Antimony and lithium atoms are nearly tetrahedrally surrounded. Characteristic bond distances and angles are: Sb—Si 253.2(1); Sb—Li 293.3(4); O—Li 201.1(8) pm as well as Si—Sb—Si 94.2(1); Sb—Li—Sb 130.7(3); Li—Sb—Li 144.6(4)°.
    Notes: Tris(trimethylsilyl)stiban reagiert mit Methyllithium in 1,2-Dimethoxyäthan (DME) zu Lithium-bis(trimethylsilyl)antimonid · DME 1 und Tetramethylsilan. Das Antimonid 1 kristallisiert tetragonal in der azentrischen Raumgruppe I42d mit den bei der Meßtemperatur von -85°C bestimmten Abmessungen der Elementarzelle: a = 1004,95(2); c = 3714,70(1) pm; Z = 8. Nach den Ergebnissen einer Röntgenstrukturanalyse (R = 0,030) liegen Makromoleküle in Form geschraubter Ketten vor, die sich aus Bis(trimethylsilyl)stibano-Resten und DME-komplexierten Lithiumatomen in alternierender Reihenfolge aufbauen. Sie können durch ein Dornberger-Schiff-Symbol wie P(2)21(2) charakterisiert werden und stapeln sich nach den von O'Keeffe und Andersson abgeleiteten Regeln. Die Antimon- und Lithiumatome sind verzerrt tetraedrisch koordiniert. Charakteristische Bindungslängen und -winkel sind: Sb—Si 253,2(1); Sb—Li 293,3(4); O—Li 201,1(8) pm sowie Si—Sb—Si 94,2(1); Sb—Li—Sb 130,7(3); Li—Sb—Li 144,6(4)°.
