KGA-2727 is a potent and selective SGLT1 inhibitor for the treatment of diabete. KGA-2727 inhibited SGLT1 potently and highly selectively in an in vitro assay using cells transiently expressing recombinant SGLTs. KGA-2727 inhibited the absorption of glucose but not that of fructose. It has inhibition constant (Ki) values of 97 and 13,600 nM for human (h) SGLT1 and hSGLT2, respectively.

Biological Activity
| ln Vitro | Good linearity for human SGLT1 and SGLT2 is demonstrated by the Dixon plot study of KGA-2727. Dixon plot results show that KGA-2727 inhibits these SGLTs in a way that is competitive. KGA2727 inhibits SGLT1 and SGLT2's absorption of methyl-D-glucopyranoside (AMG) in a dose-dependent manner [1]. |
| ln Vivo | KGA-2727 decreased the rise in plasma glucose following a glucose load in the oral glucose tolerance test conducted in streptozotocin-induced diabetic rats, suggesting that KGA-2727 ameliorated postprandial hyperglycemia [1]. In Zucker diabetic fat (ZDF) rats, long-term administration of KGA-2727 decreased plasma glucose and glycated hemoglobin levels. KGA-2727 can also improve the morphological alterations of the pancreatic islets and renal distal tubules in ZDF rats, maintaining glucose-stimulated insulin production and lowering urine glucose excretion [1]. |

Solubility in Formulation 1: ≥ 5 mg/mL (9.32 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 5 mg/mL (9.32 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 5 mg/mL (9.32 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 50.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
