Douglas Riexinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20080045461
    Abstract: The subject matter described herein provides novel human glucagon-like peptide-1 (GLP-1) receptor modulators that have biological activity similar or superior to native GLP-1 peptide and thus are useful for the treatment or prevention of diseases or disorders associated with GLP activity. The described compounds include chemically modified peptides that may stimulate insulin secretion in type II diabetics, but also produce other beneficial insulinotropic responses. These synthetic peptide GLP-1 receptor modulators exhibit increased stability to proteolytic cleavage making them ideal therapeutic candidates for oral or parenteral administration. The disclosed and claimed peptides show desirable pharmacokinetic properties and desirable potency in efficacy models of diabetes.

  • Publication number: 20070149763
    Abstract: The present invention provides the crystal structure of BACE-1 complexed with both an active site inhibitor and an exosite peptide containing the core sequence YPYFI. The crystal structure shows the exosite peptide bound to the BACE-1 exosite and identifies a novel peptide binding site on the surface of the BACE-1. The invention also provides the residues that make up the exosite binding site within 6.0 ? of any exosite peptide atom which are: E316, K317, F318, P319, F322, G325, E326, Q327, L328, V329, C330, W331, Q332, A333, T335, D372, V373, A374, S376, D378, D379, C380, Y381.
