  • Patent number: 9182414
    Abstract: The present invention concerns combination of an amount of a BRS-3 agonist with an amount of a dipeptidyl peptidase IV (DPP-IV) inhibitor such that the combination provides an effect in lowering a blood glucose level or in increasing a blood GLP-1 level in a subject over that provided by the amount of the BRS-3 agonist alone and by the amount of the DPP-IV inhibitor alone and the use of such a combination for treating or preventing obesity and diabetes and conditions related thereto and conditions ameliorated by increasing a blood GLP-1 level. The present invention also relates to the use of a G protein-coupled receptor to screen for GLP-1 secretagogues.

  • Patent number: 8883714
    Abstract: The present invention relates to methods of using GPR119 receptor to identify peptide YY (PYY) secretagogues and compounds useful in the treatment of conditions modulated by PYY, such as conditions modulated by stimulation of NPY Y2 receptor (Y2R). Agonists of GPR119 receptor are useful as therapeutic agents for treating or preventing a condition modulated by PYY, such as a condition modulated by stimulation of Y2R. Conditions modulated by PYY such as may be a condition modulated by stimulation of Y2R include bone-related conditions, metabolic disorders, angiogenesis-related conditions, ischemia-related conditions, convulsive disorders, malabsorptive disorders, cancers, and inflammatory disorders.

  • Publication number: 20120208843
    Abstract: The present invention relates to a method for identifying a metabolic stabilizing compound, comprising: a) contacting a candidate compound with GPR35, and b) determining whether GPR35 functionality is increased, wherein an increase in GPR35 functionality is indicative of the candidate compound being a metabolic stabilizing compound. The invention further relates to a method for treating or preventing a metabolic-related disorder, comprising administering to an individual in need thereof an effective amount of a GPR35 modulator.

  • Publication number: 20110319451
    Abstract: The present invention relates to a method for identifying a glycemic stabilizing compound, by: a) contacting a candidate compound with a 5-HT6 receptor, b) determining whether 5-HT6 receptor functionality is increased, and c) determining whether a glycemic marker is directly modulated, where an increase in 5-HT6 receptor functionality and direct modulation of a glycemic marker identifies the candidate compound as the glycemic stabilizing compound. In addition, the invention relates to a method for identifying a glycemic stabilizing compound, by: a) contacting a single dose of a candidate compound with a 5-HT6 receptor, b) determining whether 5-HT6 receptor functionality is increased, and c) determining whether a glycemic marker is directly modulated, where an increase in 5-HT6 receptor functionality and direct modulation of a glycemic marker identifies the candidate compound as the glycemic stabilizing compound.
