摘要: An anti-tumor substance which is not only heatstable but also has low inflaming and pain-inducing properties and low pyrogenic activity is disclosed. The substance is prepared by disrupting cells of bacteria belonging to hemolytic streptococci, extracting from the disrupted material a water-insoluble substance and treating the substance with one or more proteases and, optionally, with one or more nucleases.

摘要: The present invention provides a novel amphipathic substance having tumor necrosis factor (TNF) inducing activity. This substance is an amphipathic substance obtained by extraction from several kinds of acid-fast bacteria, and has excellent TNF inducing activity. The toxicity of the substance is much lower than that of the conventional amphipathic substances having TNF inducing activity.
