Identification of Diaryl Ether-Based Ligands for Estrogen-Related Receptor α as Potential Antidiabetic Agents
摘要:
Estrogen-related receptor a (ERR alpha) is an orphan nuclear receptor that has been functionally implicated in the regulation of energy homeostasis. Herein is described the development of diaryl ether based thiazolidenediones, which function as selective ligands against this receptor. Series optimization provided several potent analogues that inhibit the recruitment of a coactivator peptide fragment in in vitro biochemical assays (IC50 < 150 nM) and cellular two-hybrid reporter assays against the ligand binding domain (IC50 = 1-5 mu M). A cocrystal structure of the ligand-binding domain of ERR alpha with lead compound 29 revealed the presence of a covalent interaction between the protein and ligand, which has been shown to be reversible. In diet-induced murine models of obesity and in an overt diabetic rat model, oral administration of 29 normalized insulin and circulating triglyceride levels, improved insulin sensitivity, and was body weight neutral. This provides the first demonstration of functional activities of an ERRa ligand in metabolic animal models.

Based on the lead therapeutic agent NSC 240898, a new series of heterocyclic inhibitors of the BoNT serotype A metalloprotease has been generated. Highlights of the synthetic sequences include Sonogashira couplings of polysubstituted building blocks and gold-catalyzed indole formations. Preliminary structure-activity relationship studies afford detailed insights into the steric and electrostatic properties of the pharmacophore of this molecular scaffold.
