Abstract: Compositions are administered to a patient (preferably by injection and locally) to treat a variety of conditions including inflammation associated with trauma and with certain aspects of diseases such as rheumatoid arthritis, psoriasis, insulin-dependent diabetes, cutaneous lymphomas, duodenal ulcer, chronic proctitis, lymphocytic thyroiditis, hemorphagic shock, reperfusion injury during transplantation and multiple sclerosis. The compositions are pharmaceutically acceptable injectable formulations which include an active component in a pharmaceutically acceptable carrier. The active component is a chlorate or selenate which inhibits the natural biochemical sulfation process and/or a sulfatase enzyme which removes a sulfate from a specific position of a saccharide molecule which makes up a part of a natural ligand for L-selectin. Removal of the sulfate from the ligand hinders the ability of the ligand to bind to its natural receptor (i.e.

Abstract: Sulfated oligosaccharides which bind to L-selectin receptors and act as agonists are formulated into pharmaceutical formulations and administered by injection to treat inflammation. Compounds which act as metabolic inhibitors of carbohydrate sulfation and inhibit the sulfation of naturally occurring ligands for L-selectin receptors are administered locally by injection to alleviate and/or prevent inflammation. The sulfated oligosaccharides can be administered in combination with the chlorates and sulfatases in order to obtain a combined effect which is useful in preventing and/or alleviating inflammation. A preferred group of ligands are obtained by the hydrolysis of GlyCAM-1 by separation procedures including high pH anion exchange chromatography. The invention describes compounds that have the recognition determinants for L-selectin on GlyCAM-1 as Galactose-6-sulfate and/or N-acetylglucosamine-6-sulfate, in concert with sialic acid and fucose.

Abstract: Substantially pure cromolyn binding protein is prepared by means of affinity chromatography of cromolyn derivatives bound to insoluble matrices. Aminocromolyn is prepared by a six-step synthesis and amine derivatives thereof are prepared by conventional means. Obtaining a compound having an amine group instead of the OH group at the 2-carbon of the propane link of cromolyn permits many kinds of reactions without interfering with the portion of the cromolyn molecule with causes its pharmacological activity. The cromolyn derivatives can be conjugated to proteins such as BSA by means of glutaraldehyde cross-linking and such conjugates can be covalently bound to agarose beads. Cromolyn binding protein can be isolated by passing lysates of RBL-2H3 cells through chromatographic columns packed with such beads. The cromolyn binding protein can be further purified by means of lectin-agarose columns.
