    Description / Table of Contents: Antibiotics from Gliding bacteria, XV. - Myxalamides A, B, C, and D, a Group o Homologous Antibiotics from Myxococcus xanthus Mx x12 (Myxobacterales)A new antibiotic complex, called myxalamides, was isolated from the cells of Myxococcus xanthus Mx x12 (GBF). After preliminary purification using florisil the myxalamides were separated by reversed-phase chromatography to give four components. The spectroscopic investigation of the main component, myxalamide B (1), revealed the structure of an alaninol amide with a highly unsaturated, branched fatty acid. The xyxalamides A (3), C(4) D(5) are amides of homologous fatty acids and alaninol.
    Notes: Aus den Zellen von Myxococcus xanthus Mx x12 (GBF) wurde ein neuer Antibiotika-Komplex, genannt Myxalamide, isoliert. Nach Vorreinigung an Florisil wurden die myxalamide durch chromatographie an einer Umkehrphase in vier Komponenten aufgetrennt. Die spektroskopische Untersuchung der Hauptkomponente, Myxalamid B (1), ergibt die Struktur eines Alaninolamids mit einer verzweigten, hohungesättigten Fettsäure. Die Myxalamide A (3), C(4) und D(5) sind Amide aus homologen Fettsäuren und Alaninol.
