EC50: 1.1±0.06 nM for hSGLT2

Selective inhibition of SGLT2 has been proposed to aid in the normalization of plasma glucose levels in patients with diabetes by preventing the renal glucose reabsorption process and promoting glucose excretion in urine. Dapagliflozin is a potent, selective Renal Sodium-Dependent Glucose Cotransporter 2 (SGLT2) inhibitor.

In vitro: EC50 values of 1.1 nM for hSGLT2 and 1.4 μM for hSGLT1 determined for Dapagliflozin corresponded to 1200-fold selectivity for SGLT2 as compared with phlorizin’s 10-fold selectivity. Dapagliflozin inhibitory potencies against rat SGLT (rSGLT)2 and hSGLT2 were comparable, but the selectivity of Dapagliflozin for rSGLT2 versus rSGLT1 decreased to 200-fold [1].

In vivo: In vivo, dapagliflozin acutely induced renal glucose excretion in diabetic and normal rats, improved glucose tolerance in normal rats, as well as reduced hyperglycemia in Zucker diabetic fatty rats after single oral doses ranging between 0.1 and 1.0 mg/kg [2].
