Background

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].

Clinical trial: Dapagliflozin dosing at 1, 2.5 and 5 mg/day is effective in reducing glycaemic levels and body weight in treatment-naive patients with type 2 diabetes. Dapagliflozin was well tolerated [3].

Protocol

Cell experiment:[1]
Cell lines	Chinese hamster ovary cells stably expressing human SGLT2 and SGLT1
Reaction Conditions	1.1 nM (EC50)
Applications	Dapagliflozin inhibited accumulation of radiolabeled α-methyl-D-glucopyranoside, with EC50 values of 1.1 nM for human SGLT2 (hSGLT2) and 1.4 μM for hSGLT1.
Animal experiment:[1]
Animal models	Sprague-Dawley rats
Dosage form	0.1, 1.0, and 10 mg/kg Administered orally
Applications	In normal rats, a single oral dose of 0.1, 1.0, and 10 mg/kg of dapagliflozin induced respective losses of 550, 1100, and 1900 mg of glucose per 200 g of body weight over 24 h. In streptozotocin-induced diabetic rats, a single oral dose of 0.1 mg/kg of dapagliflozin resulted in a 55% reduction in blood glucose level. The above correlation of SGLT2 inhibition, glucosuria, and blood glucose-lowering effects suggest that selective SGLT2 inhibition by dapagliflozin holds promise as a viable approach to treat type 2 diabetes.
