    摘要: The disclosed invention relates to methods of modifying peptide compositions to increase stability and delivery efficiency. Specifically, the disclosed invention relates to methods to increase the stability and delivery efficiency of protein kinase C (PKC) modulatory peptide compositions. A "therapeutic peptide composition" comprises a "carrier peptide" and a "cargo peptide." A "carrier peptide" is a peptide or amino acid sequence within a peptide that facilitates the cellular uptake of the therapeutic peptide composition. The "cargo peptide" is a PKC modulatory peptide. Peptide modifications to either the carrier peptide, the cargo peptide, or both, which are described herein increase the stability and delivery efficiency of therapeutic peptide compositions by reducing disulfide bond exchange, physical stability, reducing proteolytic degradation, and increasing efficiency of cellular uptake.

    摘要: Compounds having activity for lowering parathyroid hormone levels are described. In one embodiment, the compounds are comprised of a contiguous sequence of subunits, X 1 - X 2 - X 3 - X 4 - X 5 - X 6 - X 7 , wherein the X 1 subunit comprises a thiol-containing moiety and the distribution of charge on the X 2 -X 7 subunits provides the desired activity. Methods of using the compounds for treating hyperparathyroidism, bone disease and/or hypercalcemic disorders are also described, and in particular, methods for lowering plasma PTH and serum calcium are provided. The compounds can be used to treat subjects having, for example: primary, secondary or tertiary hyperparathyroidism; hypercalcemia of malignancy; metastatic bone disease; or osteoporosis.

    摘要: The present invention provides peptides for inhibiting various protein kinase isozymes. The peptide can be directed to any region of the protein kinase C isozyme, and in one embodiment, is directed to the V5 domain. The peptide can be conjugated to a carrier, in a releasable or non-releasable manner. The peptides can be used to inhibit angiogenesis and/or vascular permeability. The peptides can be used to treat subjects having, for example, cancer, diabetic blindness, macular degeneration, rheumatoid arthritis, or psoriasis.
