Glycosylated dihydrochalcones as potent and selective sodium glucose co-transporter 2 (SGLT2) inhibitors

A series of glucose conjugates was synthesized and tested for inhibition of SGLT1 and SGLT2. The core structure was derived from compound 1a. Modification of the benzofuran moiety and 4′-substituent of the phenyl ring in compound 1a improved selectivity at SGLT2. Select compounds were compared to 1a in metabolic stability and in vivo efficacy studies.
