  • Patent number: 8927489
    Abstract: The present invention provides a pharmaceutical composition for the sustained release of C-peptide. The composition is in the form of a gel containing C-peptide. The gel formation is achieved by the adjustment of pH of the composition and/or by addition of divalent metal ions. The composition does not include any other gel-forming agents.

  • Publication number: 20140378394
    Abstract: The present invention relates to the development of improved methods for treating erectile dysfunction associated with diabetes. Significantly, such dosing regimens can be combined with established methods for treating sexual dysfunction, including phosphodiesterase-5 (PDE5) inhibitors such as those sold under the trademark VIAGRA® to provide for significantly improved efficacy compared to the PDE5 inhibitor alone.

  • Patent number: 6610649
    Abstract: The invention features peptides that are fragments of the human insulin C-peptide, which peptides include the sequence ELGGGPGAG or a fragment thereof, or the sequence EGSLQ or a fragment thereof. The peptides have the ability to stimulate Na+K+ATPase activity. Also provided are biomimetic organic compounds exhibiting activation of Na+K+ATPase activity and/or cellular binding to renal tubule cells and fibroblasts. Such peptides and compounds are useful in combating diabetes and diabetic complications, or for stimulating Na+K+ATPase activity.
