title: [Isolation and structure of the active component of the antitumor agent blastolysin].
abstract: Active principle of blastolysin, comprising ca. 40% of the total weight of Lactobacillus bulgaricus cell wall preparation, has been isolated and structurally studied by chemical and spectral methods. The substance a glycopeptide with Mr aa. 10,000, consists of two tetrasaccharide moieties connected by oligopeptide bridges; glycerophosphate, glucose, and galactose moieties are also attached to N-acetylmuramyl residue of the peptidoglucan core. Tetrasaccharide-containing muramylpeptides were shown to be responsible for the antitumour activity.
