A new class of mild sodium-dependent glucose cotransporter 2 (SGLT2) inhibitors with glucosyl isoflavone structure were prepared from puerarin. The in vitro biological activity was performed on Chinese hamster ovary (CHO) cells stably expressing human SGLT2 while taking[14C]-methyl-D-glucopyranoside ([14C]-AMG) as the substrate. Some derivatives exhibited potent activity against SGLT2 with IC50 among 20~30 nmol/L. The inhibitory activities of derivatives with more lipophilic substitutents were more potent. The compounds whose 4'-OH and 7-OH were both protected with alkyl or benzyl are more active than those with only the 4'-OH being protected. The inhibitory activity of some homologues has no great difference. 4'-O-n-Hexylpuerarin (1i), 4'-O-n-octylpuerarin (1j), 4'-O-(4-methylbenzyl)puerarin (1l), 4'-O-(4-methoxylbenzyl)-puerarin (1m) with moderate inhibitory activity against SGLT2 may have anti-oxidant and anti-atherosclerotic properties due to the presence of Ar-OH in the molecule structure, which will be very useful to treat diabetic disease and cardiovascular complications.
