    Description / Table of Contents: Zusammenfassung δ-N-Hydroxy-L-arginin wurde aus Kulturfiltraten des Dermatophyten Nannizzia gypsea (Familie Gymnoascaceae, Ordnung Eurotiales, Klasse Ascomycetes) isoliert. Das Antibioticum hemmt verschiedene Bakterien und Pilze. Mit L-Arginin und L-Citrullin läßt sich die Wirkung aufheben. Die Reinigung erfolgte durch Ionenaustausch an Dowex 50WX8 mit Ammoniumhydroxid, präparative Chromatographie an Kieselgel (Laufmittel: n-Propanol-Wasser), Säulenchromatographie an Cellulose und Elution mit Äthanol-Essigsäure-Wasser. Dabei entstand das Acetat, welches zum Schluß wieder in das ursprüngliche Antibioticum überführt werden konnte. Zur chemischen Charakterisierung und Ermittlung der Struktur wurden unter anderem Gaschromatographie-Massenspektrometrie, 13C- und Protonen-NMR-Spektrometrie benutzt.
    Notes: Summary δ-N-hydroxy-L-arginine was isolated from culture filtrates of Nannizzia gypsea, a dermatophyte of the family Gymnoascaceae, order Eurotiales, class Ascomycetes. Several bacteria and fungi are inhibited by the antibiotic. The inhibition is compensated by L-arginine and L-citrulline. The substance has been purified by: ion exchange on Dowex 50WX8 with ammonium hydroxide, chromatography with n-propanol-water on silicagel layers, column chromatography on cellulose and elution with ethanol-acetic acid-water, yielding the acetate of the compound. The antibiotic was then obtained from the acetate. Gas chromatography-mass spectrometry, 1H- and 13C-NMR and other techniques have been applied in order to elucidate the constitution and configuration of the novel compound.

    Description / Table of Contents: Zusammenfassung Aus den Kulturen von Streptomyces violaceoniger, Stamm Tü 96, wurden zwei neue lipophile Antibiotica, Lysolipin I und Lysolipin X, isoliert. Das letztere ist sehr unstabil und geht leicht in Lysolipin I über. Das tief gelb gefärbte, optisch aktive Lysolipin I besitzt die Bruttoformel C29H24CINO11 und wurde durch das IR-, UV-, das H-NMR-und das 13C-NMR-Spektrum charakterisiert. Es liegt ein neuartiges Chinon-Antibioticum vor. Lysolipin I ist hoch wirksam gegen Gram-positive und Gram-negative Bakterien, gegen Enterobakterien allerdings nur bei permeationsgeschädigten Stämmen. Lysolipin I übt auf Bakterienzellen eine lytische Wirkung aus. Sie wird durch verschiedene Lipide antagonisiert. Angriffsort des Antibioticums ist die Biosynthese der Bakterienzellwand. Eine Wechselwirkung mit dem Carrier-Lipid von Murein-Zwischenstufen wurde wahrscheinlich gemacht.
    Notes: Abstract From the cultures of Streptomyces violaceoniger, strain Tü 96, two new lipophilic antibioties, Lysolipin I and Lysolipin X were isolated. The latter one is chemically unstable and is easily transformed to Lysolipin I. The deeply yellow Lysolipin I has a molecular formula C29H24CINO11. It was characterized by the ir, uv, H-nmr and 13C-nmr spectra, which make a quinone structure very probable. Lysolipin I is active against Gram-positive and Gram-negative bacteria. However, enterobacteriae are only inhibited in high dilution, when the membrane permeation is damaged. Lysolipin I acts lytically against bacterial cells. Its activity is decreased by several lipids. The site of action is the biosynthesis of bacterial cell walls, an interaction with the carrier lipid for mureine intermediates being probable.
