Abstract

The invention comprises lipo-polysaccharides obtainable by cultivating bacteria of the species Proteus vulgaris or mirabilis aerobically on a fully synthetic nutrient medium and either (a) dialysing the separated cell material, treating the non-dialysable material with a phenol-water mixture at an elevated temperature, extracting the aqueous phase with ether, and dialysing the aqueous phase, if desired after precipitating its valuable content with ethanol, and, if desired, purifying the material; or (b) dialysing the culture medium freed from cell material, precipitating the aqueous solution freed from insoluble material with ethanol, dialysing the precipitated material and fractionating it with ethanol, acetone or quaternary ammonium compounds containing a high molecular weight aliphatic radical and being soluble in water and ethanol, and, if desired, purifying the material. The acylated lipo-polysaccharides derived by treatment of the above products with acylating agents introducing the radical of aliphatic carboxylic acids having 1-4 carbon atoms, are also novel compounds. The lipopolysaccharides are of high molecular weight, possess no substantial antigenic and pathogenic activity but are active in leucocyte emigration tests and show antilipemic activity. They have a sugar content of at least 20%, phosphorus content of at least 1,7% and a sedimentation constant of 1,9 X 10-13. The novel compounds are used in pharmaceutical preparations (see Group VI).ALSO:Pharmaceutical preparations for topical, enteral or parenteral administration contain one or more lipo-polysaccharides obtainable by cultivating bacteria of the species Protens vulgaris or mirabilis aerobically on a fully synthetic nutrient medium, and acylated products derivable from said lipo-polysaccharides by treatment with acylating agents introducing the radical of an aliphatic carboxylic acid having 1 to 4 carbon atoms, (for preparation see Group IV(a)), in admixture with solid or liquid pharmaceutical carriers. The preparations may be used in the form of creams, salves, tablets, dragees, capsules, pearls, solutions, suspensions, or emulsions. They may be sterilized and/or contain preserving, stabilizing, wetting or emulsifying agents, salts, buffers or other therapeutically active substances. They contain the lipo-polysaccharides in an amount of 0,001g -100g per dosage unit.
