Discovery of GCC5694A: A potent and selective sodium glucose co-transporter 2 inhibitor for the treatment of type 2 diabetes.

Sodium-dependent glucose co-transporter 2 (SGLT2) has emerged as a promising drug target for the treatment of type 2 diabetes, and recently, several SGLT2 inhibitors have been approved for clinical use. A series of molecules with a C-aryl glucoside scaffold was designed and synthesized for biological evaluation. Among the molecules tested, a dihydrobenzofuran-containing analog, 14g (GCC5694A), exhibited excellentin vitro activity against SGLT2 (IC50 = 0.460 nM), good selectivity for SGLT1, and good metabolic stability. Data from further evaluation of the compound in animal models showed that this molecule is a promising candidate for development as an anti-diabetic agent.
