NOVEL CRYSTALLINE FORMS OF ANTIDIABETIC COMPOUNDS

摘要

A novel crystalline anhydrate of the free acid and a crystalline anhydrous besylate salt of a selective PPAR gamma partial agonist which has a fused bicyclic aromatic group attached to an oxypropanoic acid moiety are stable and non-hygroscopic. The compounds are suitable for preparing pharmaceutical formulations for the treatment of type 2 diabetes, hyperglycemia, obesity, and dyslipidemia.
