  • Patent number: 7267822
    Abstract: Novel oligonucleotides comprising a sequence derived by a computer program are provided for inhibiting cytotoxic activity of lymphocytic cells, inhibiting production of inflammatory cytokines and inflammatory responses associated with those cytokines, inhibiting the activity of heme-containing enzymes and delaying the onset of an autoimmune disease. By combining the subject compositions with mixtures of cells comprising lymphocytic cells and cells which would otherwise activate the lymphocytic cells, lysis of the target cells can be substantially inhibited. The oligopeptides may be joined to a variety of other groups or compounds for varying the activity of the subject composition. The subject compositions may be administered by any convenient means to inhibit lymphocytic attack on tissue, particularly involved with xenogeneic or allogeneic transplants or to inhibit the production of inflammatory cytokines and inflammatory responses associated therewith.
    Type: Grant
    Filed: February 17, 2004
    Date of Patent: September 11, 2007
    Assignee: Genzyme Corporation
    Inventors: Roland Buelow, Gèrard Grassy, Bernard Calas

  • Patent number: 6696545
    Abstract: Novel oligopeptides comprising a sequence derived by a computer program are provided for use in inhibiting cytotoxic activity of lymphocytic cells, inhibiting the production of inflammatory cytokines and inflammatory responses associated with those cytokines, inhibiting the activity of heme-containing enzymes and delaying the onset of an autoimmune disease in a mammal at risk of developing the disease. By combining the subject compositions with mixtures of cells comprising lymphocytic cells and cells which would otherwise activate the lymphocytic cells, lysis of the target cells can be substantially inhibited. The oligopeptides may be joined to a wide variety of other groups or compounds for varying the activity of the subject compositions.

  • Patent number: 6620910
    Abstract: Compound of formula (I): Z1-X1-X2-X3-Gly-Thr-Phe-Thr-Ser-X4-X5-Ser-X6-X7-X8  (I) wherein: Z1, substituent of the terminal amino group, represents hydrogen, alkyl or acyl, or arylcarbonyl, heteroarylcarbonyl, arylalkylcarbonyl, heteroarylcarbonyl, aryloxycarbonyl, arylalkoxycarbonyl or alkoxycarbonyl each of which is optionally substituted, Z2 (SEQ ID NO: 1), substituent of the terminal carbonyl group, represents hydroxy, alkoxy or optionally substituted amino, X1 to X14 each represents an amino acid residue having the D or L configuration as defined in the description, X15 represents a bond or an arginine residue (Arg). Medicinal products containing the same are useful as tGLP-1 agonists.

  • Patent number: 5175254
    Abstract: This invention relates to solid phase peptide synthesis.Solid phase peptide synthesis is accomplished on polyacrylic resins (such as those described in EP 0 079 812 and EP 0 081 408 which correspond to U.S. Pat. Nos. 4,436,874 and 4,439,545 respectively) by a method which includes in the coupling protocol steps of washing the resin in water and/or aqueous solution(s).
