  • Patent number: 7875596
    Abstract: Dermatan sulfates and/or O-desulfated heparins useful in treating and preventing heparinoid-induced autoimmune responses, in particular heparin-induced thrombocytopenia (HIT) and its associated disease states. The dermatan sulfates comprise repeating disulfated and/or trisulfated disaccharide units of L-iduronic acid and N-acetyl-D-galactosamine. The O-desulfated heparins comprise heparin molecules selectively O-desulfated at the 2-O and/or 3-O positions of the uronic acid and glucosamine saccharide residues. Particularly effective dermatan sulfate HIT antagonists have a mean molecular weight of from about 2000 to about 10,000 Daltons.

  • Patent number: 6518244
    Abstract: Combined use of a heparin cofactor II agonist and a platelet GPIIb/IIIa receptor antagonist to inhibit both platelet aggregation and thrombin generation resulting from disease, injury or responses to wound repairs. The combined use of the heparin cofactor II agonist and the platelet GPIIb/IIIa receptor antagonist can achieve these therapeutic benefits while at the same time minimizing or reducing the risk of hemorrhagic side effects (e.g., prolonged bleeding), and without causing undesired antigenic responses. Moreover, certain subtherapeutic amounts of the heparin cofactor II agonist with certain subtherapeutic amounts of a platelet GPIIb/IIIa receptor antagonist can, in combination, be therapeutically effective in inhibiting both platelet aggregation and thrombin generation.

  • Patent number: 6409987
    Abstract: A selectively targeted agent comprising a dermatan sulfate having more than about 25% repeating L-iduronic acid→4,6-di-O-sulfated N-acetyl-D-galactosamine disaccharide units that is covalently attached or bonded to a radioactive metal-ion binding moiety. The targeted agent is useful in preparing radiagnostic and/or radiopharmaceutical agents for diagnostic and/or therapeutic treatment when combined with an appropriate radioactive metal ion such as 99mTc, 186Re or 188Re.

  • Patent number: 5728874
    Abstract: The present invention relates to achiral polyurea oligomers, their uses and formulations as anti-HIV pharmaceuticals and to a process for the preparation of narrow mono- and polydispersed oligomers as an emodiment of the invention. The achiral oligomers are derived from repeating units of the monomer 4,4'-diamino-biphenyl-3,3'-disulfonic acid and are water soluble, have a rigid backbone, possess ordered anionic spacing and have a number average molecular weight of <20,000. The process relates to the synthesis of narrow poly- and mono-dipersed oligomers comprising the steps of: 1) restricting the crude olydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture; and/or 2) isolating the monodispersed anionic oligomer; and 3) optionally converting the narrow poly- or mono-dispersed anionic oligomer salt from Step 1 or 2 to a desired pharmaceutically-acceptable salt, especially a solim or potassium salt.
