  • Patent number: 4454315
    Abstract: It has been found that water-insoluble, thermogelable .beta.-1,3-glucan produced by microorganisms, lower polymers obtainable upon partial hydrolysis of the glucan or, carboxymethylated derivatives of said glucan or of said lower polymers are useful for inhibiting growth of tumors in a warm-blooded animal. The inhibitory activity against various tumors of these polysaccharides is very strong and significant whenever administered to warm-blooded animals from the early to very late stage of tumor progression or even when administered prior to plantation of tumors. The carboxymethylated derivatives above-mentioned are novel water-soluble compounds which can be produced by carboxymethylation of said glucan and partial hydrolyzate thereof.

  • Patent number: 4386026
    Abstract: Cell-specific ligands comprising conjugates of saccharides and amino acids or peptides are synthesized from amino acids such as ornithine, lysine, peptides such as dilysine, diornithine or oligolysine and selected saccharides having reactive functional groups protected by appropriate blocking groups. Such glycopeptides are useful as tissue specific substances, which when coupled with bioactive materials through metabolizable or hydrolyzable linkages, deliver such bioactive materials to the selected site. In this manner, antiinflammatory drugs such as dexamethasone are linked through a metabolizable or hydrolyzable linkage and on administration to an animal suffering from inflammatory disease carries the drug to the site of inflammation for intracellular release. Other examples include the macrophage ligand N.sup.2 -N.sup.2, N.sup.6 -Bis-[3-(.alpha.-D-mannopyranosylthio)propionyl]-6-lysyl-N.sup.6 -[3-(.alpha.-D-mannopyranosylthio)propionyl]-L-lysine, 5, which when coupled to .beta.

  • Patent number: 4241054
    Abstract: Non-absorbable polyol polyesters dissolve toxic lipophilic compounds in the stomach and intestine of humans and lower animals and thus decrease their absorption. The polyol polyesters also dissolve the toxic, lipophilic materials and their metabolites if they are excreted in bile, and prevent their resorption. The invention thus provides a means for detoxifying humans and lower animals which have ingested toxic lipophilic materials (e.g., DDT, Kepone, PCB, PBB) by accelerating the excretion of such materials that have accumulated in the body. The process involves oral administration to a human or lower animal in need of such treatment of a sufficient amount of a non-absorbable polyol fatty acid polyester to effect detoxification.

  • Patent number: 4147860
    Abstract: A process for preparing nitroaromatic glycosides is described. The process comprises contacting an acetylated glycoside of maltotetraose, maltopentaose or maltohexaose with a phenol, nitrating the resulting product to place a NO.sub.2 group on the aromatic moiety and deacetylating the nitrated product. The nitroaromatic glycosides are useful as standard substrates for the assay of .alpha.-amylase.

  • Patent number: 4137401
    Abstract: Carbohydrate antigenic determinants containing a glycosidically linked bridging arm are synthesized and coupled to carrier molecules to form artificial antigens, and to solid supports to form immunoabsorbants. These artificial antigens are used to detect antibodies to the carbohydrate haptens, and to raise antisera specific for the carbohydrate antigenic determinants. The immunoabsorbants are used to purify or remove antibodies to the carbohydrate haptens. Specific examples are given to the synthesis of the Lewis-a, Lewis-b, B, and H(O) blood group antigens; to the preparation of antisera to these artificial antigens, and to the preparation of immunoabsorbants specific for antibodies to these antigens.

  • Patent number: 4107425
    Abstract: Anomerically pure 1-.alpha.- and 1-.beta.-esters of 2,3,4,6-Tetra-O-benzyl-D-glucopyranose have been prepared in high yield by controlling the stereochemistry of 1-O-acylation of appropriately protected D-glucose. 2,3,4,6-tetra-O-benzyl-D-glucopyranose is metalated with n-butyllithium in either tetrahydrofuran or anhydrous benzene and the metalated product acylated with an appropriate alkyl, alkenyl, or aryl acid chloride. Hydrogenation of the acyl glucopyranose, when derived from a saturated acid chloride, yields the appropriate 1-.alpha.- or 1-.beta.-D-glucose ester. Reaction in tetrahydrofuran produces the .alpha.-anomer while reaction in anhydrous benzene produces the .beta.-anomer.

  • Patent number: 4104464
    Abstract: A soap-free sucrose ester-containing surfactant is obtained by transesterifying sucrose with at least one fatty acid triglyceride to produce a solid material containing sucrose esters, glycerides and fatty acid soaps, and treating this material with a solution of a metal salt in water or an alkanol to produce a second solid material and separating the soap-free product containing sucrose esters by dissolving the esters present in an alkanol and evaporating the alkanolic solution to dryness. Glycerides are removed, where desired, by extracting with an organic solvent.
