(2R)-2-Ethylchromane-2-carboxylic Acids: Discovery of Novel PPARα/γ Dual Agonists as Antihyperglycemic and Hypolipidemic Agents
摘要:
A series of chromane-2-carboxylic acid derivatives was synthesized and evaluated for PPAR agonist activities. A structure-activity relationship was developed toward PPARalpha/gamma dual agonism. As a result, (2R)-7-{3-[2-chloro-4-(4-fluorophenoxy)phenoxy]propoxy}-2-ethylchromane-2-carboxylic acid (48) was identified as a potent, structurally novel, selective PPARalpha/gamma dual agonist. Compound 48 exhibited substantial antihyperglycemic and hypolipidemic activities when orally administered in three different animal models: the db/db mouse type 2 diabetes model, a Syrian hamster lipid model, and a dog lipid model.
