  • Publication number: 20200024322
    Abstract: The present invention relates to compounds having activity at both the human glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. The present invention also relates to compounds having an extended duration of action at each of these receptors. Furthermore, the present invention relates to compounds that may be administered orally. Compounds may be useful in the treatment of type 2 diabetes mellitus (“T2DM”). Also, the compounds may be useful in the treatment of obesity.

  • Publication number: 20190077834
    Abstract: Compounds comprising peptides capable of binding C3 protein and inhibiting complement activation are disclosed. The compounds comprise compstatin analogs in which the N-terminus contains an added or substituted component that improves (1) the peptide's binding affinity to C3 or its fragments, (2) the peptide's solubility in aqueous liquids, (3) the peptide's plasma stability, (4) the peptide's in vivo retention and/or (5) the peptide's bioavailability, as compared with an unmodified compstatin peptide under equivalent conditions. Pharmaceutical compositions and methods of using the compounds are also disclosed.
