Abstract
PURPOSE: An antitumor agent, containing a precipitate obtained by precipitating an extract of microbial cells of bacteria belonging to the genus Brevibacterium with a dilute acidic or alkaline aqueous solution with a solvent as an active constituent, and capable of exhibiting a remarkable antitumor activity against ascitic cancers.
CONSTITUTION: Microbial cells of bacteria, e.g. Brevibacterium lactofermentum or Brevibacterium flavum, belonging to the genus Brevibacterium are extracted with a dilute acidic or alkaline aqueous solution, and the resultant extract is then separated by the centrifugation, etc. The separated extract is acidified in the case of the alkaline extraction, and precipitated with a solvent, e.g. acetone, to collect the formed precipitate. The resultant precipitate shows a powerful antitumor activity, and is formulated and used as an injection, oral agent. etc.
