Zusammenfassung

Es werden zwei neue, chemisch verwandte Streptomyces Antibiotika beschrieben, X-948 (C29H39O7N7S ?) und X-1008 (C29H38O7N6S ?). X-948 ist wahrscheinlich identisch mit Echinomycin. Es hat sehr ähnliche physikalische Eigenschaften und gibt die gleichen Abbauprodukte (Ammoniak, 2-Chinoxalincarbonsäure, N-Methyl-l-valin,l-Alanin undd-Serin).
