Identification of potent, nonabsorbable agonists of the calcium-sensing receptor for GI-specific administration.

Abstract:

:Modulation of gastrointestinal nutrient sensing pathways provides a promising a new approach for the treatment of metabolic diseases including diabetes and obesity. The calcium-sensing receptor has been identified as a key receptor involved in mineral and amino acid nutrient sensing and thus is an attractive target for modulation in the intestine. Herein we describe the optimization of gastrointestinally restricted calcium-sensing receptor agonists starting from a 3-aminopyrrolidine-containing template leading to the identification of GI-restricted agonist 19 (GSK3004774).

  • Coupling of the antennapedia third helix to a potent antagonist of the p53/hdm2 protein-protein interaction.

    abstract::The use of cell-membrane translocating sequences for intracellular delivery of peptides can be a powerful approach to validate drug discovery targets in cellular settings. To accomplish this, a protocol has been implemented to couple the antennapedia third helix (residues 43-58) to a potent antagonist of the p53/hdm2 ...
