Abstract
A process for preparing a sulfonated product of a glycopeptide, or its corresponding ammonium or metal salts, of pharmaceutical activity, from the gastric mucosa of the duodenum of the pig, comprising: (a) hydrolyzing the animal organ in water at a temperature from about 50ºC to about 100ºC for about 10 minutes to about 45 minutes at a ph of about 1 to 10, (b) separating the acidic byproducts of hydrolysis obtained by the hydrolysis of (a) (c) diluting the product of (b) with a non-miscible solvent, for which a glycopeptide precipitates; (d) suspending the product of (c) in a tertiary heterocyclic base having a boiling point from about 100ºC to about 200º c; (e) contacting the resulting suspension of (d) with a sulfonating agent selected from the group consisting of sulfuric acid, oleum, chlorosulfonic acid and a sulfuric anhydride adduct and an organic compound at a temperature of about -40ºC to 0ºC and then raising at about 50ºC to 80º c, and recovering the resulting sulfonated product, dialyzing or contacting with ion exchange resins (f) conversion to the ammonium or metal salts of the sulfonated glycopeptide by the action of hydroxides, and/or cationic exchange resins. (g) precipitation of the salts with water-soluble organic solvents. (Machine-translation by Google Translate, not legally binding)
