Novel macrocyclic C-aryl glucoside SGLT2 inhibitors as potential antidiabetic agents.

Novel macrocyclic C-aryl glucoside SGLT2 inhibitors were designed and synthesized. Two different synthetic routes of macrocyclization were adopted to prepare novel ansa SGLT2 inhibitors. Among the compounds tested, [1,7]dioxacyclopentadecine macrocycles possessing methylthiophenyl at the distal ring 40 or ethoxyphenyl at the distal ring 23 showed the best in vitro inhibitory activity in this series to date (40, IC(50)=0.778 nM and 23, IC(50)=0.899 nM) against hSGLT2.
