  • Publication number: 20060172933
    Abstract: Modified natriuretic compounds and conjugates thereof are disclosed in the present invention. In particular, conjugated forms of hBNP are provided that include at least one modifying moiety attached thereto. The modified natriuretic compound conjugates retain activity for stimulating cGMP production, binding to NPR-A receptor, and in some embodiments an improved half-life in circulation as compared to unmodified counterpart natriuretic compounds. Oral, parenteral, enteral, subcutaneous, pulmonary, and intravenous forms of the compounds and conjugates may be prepared as treatments and/or therapies for heart conditions particularly congestive heart failure. Modifying moieties comprising oligomeric structures having a variety of lengths and configurations are also disclosed. Analogs of the natriuretic compound are also disclosed, having an amino acid sequence that is other than the native sequence.

  • Publication number: 20060018874
    Abstract: Fatty acid compositions for administration of of pharmaceutical agents, such as proteins and peptides, protein and peptide conjugates, and/or cation-polypeptide conjugate complexes. In particular, the invention provides a solid pharmaceutical composition formulated for oral administration by ingestion, having from about 0.1 to about 75% w/w fatty acid component, where the fatty acid component comprises saturated or unsaturated C4, C5, C6, C7, C8, C9, C10, C11, or C12 fatty acids and/or salts of such fatty acids; and a therapeutic agent. Further, the invention provides a liquid pharmaceutical composition formulated for oral administration by ingestion, comprising: from about 0.1 to about 10% w/v fatty acid component, where the fatty acid component comprises saturated or unsaturated C4, C5, C6, C7, C8, C9, C10, C11, or C12 fatty acids and/or salts of such fatty acids; and a therapeutic agent.

  • Publication number: 20060019874
    Abstract: The invention provides a complex including a cation and an insulin compound conjugate. The insulin compound conjugate includes insulin compound, such as human insulin or an analog thereof, conjugated to a modifying moiety, such as a polyethylene glycol moiety. The invention also includes solids and pharmaceutical compositions including such complexes, methods of making such complexes, and methods of using such complexes in the treatment of insulin compound deficiencies and other ailments. Further, the invention includes novel insulin compound conjugates and modifying moieties for use in making novel insulin compound conjugates. The invention also includes fatty acid compositions for administration of pharmaceutical agents, such as the novel insulin compound conjugates, and/or the cation-insulin compound conjugate complexes of the invention.

  • Publication number: 20060019873
    Abstract: An insulin compound coupled to a modifying moiety having a formula: —X—R1—Y-PAG-Z-R??(Formula VI) where, X, Y and Z are independently selected linking groups and each is optionally present, and X, when present, is coupled to the insulin compound by a covalent bond, either R1 or R2 is is a lower alkyl, optionally including a carbonyl group, and when R1 is a lower alkyl, R2 is a capping group, and PAG is a linear or branched carbon chain incorporating one or more alkalene glycol moieties, and optionally incorporating one or more additional moieties selected from the group consisting of —S—, —O—, —N—, and —C(O)—, and where the modifying moiety has a maximum number of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 heavy atoms.
