KGA-2727, which has a pyrazole-O-glucoside structure, as the first selective SGLT1 inhibitor.?KGA-2727 inhibited SGLT1 potently and highly selectively in an in vitro assay using cells transiently expressing recombinant SGLTs.KGA2727 dose-dependently inhibits Methyl-Dglucopyranoside (AMG) uptake by SGLT1 and SGLT2.?A Dixon plot analysis for KGA-2727 shows good linearity for human SGLT1 and SGLT2.?KGA-2727 inhibits these SGLTs in a competitive manner displayed from the results of the Dixon plot.

In a small intestine closed loop absorption test with normal rats, KGA-2727 inhibited the absorption of glucose but not that of fructose.?After oral intake of starch along with KGA-2727 in normal rats, the residual content of glucose in the gastrointestinal tract increased.?In the oral glucose tolerance test with streptozotocin-induced diabetic rats, KGA-2727 attenuated the elevation of plasma glucose after glucose loading, indicating that KGA-2727 improved postprandial hyperglycemia.?In Zucker diabetic fatty (ZDF) rats, chronic treatments with KGA-2727 reduced the levels of plasma glucose and glycated hemoglobin.?Furthermore, KGA-2727 preserved glucose-stimulated insulin secretion and reduced urinary glucose excretion with improved morphological changes of pancreatic islets and renal distal tubules in ZDF rats.?In addition, the chronic treatment with KGA-2727 increased the level of glucagon-like peptide-1 in the portal vein.
