KGA-2727

SKU: orb1219288

Description

KGA-2727 is a potent and selective SGLT1 inhibitor, with Kis of 97.4 nM and 43.5 nM for human and rat SGLT1, respectively. The selectivity ratios (Ki for SGLT2/Ki for SGLT1) of KGA-2727 are 140 (human) and 390 (rat). KGA-2727 for the treatment of diabete.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.

Bioactivity

• In Vivo:
  In the oral glucose tolerance test with streptozotocin-induced diabetic rats, KGA-2727 attenuates the elevation of plasma glucose after glucose loading, indicating that KGA-2727 improves postprandial hyperglycemia. In Zucker diabetic fatty (ZDF) rats, chronic treatments with KGA-2727 reduces the levels of plasma glucose and glycated hemoglobin. Furthermore, KGA-2727 preserves glucose-stimulated insulin secretion and reduces urinary glucose excretion with improved morphological changes of pancreatic islets and renal distal tubules in ZDF rats.
• In Vitro:
  A Dixon plot analysis for KGA-2727 displays good linearity for human SGLT1 and SGLT2. The results of the Dixon plot show that KGA-2727 inhibits these SGLTs in a competitive manner. KGA2727 dose-dependently inhibits Methyl-Dglucopyranoside (AMG) uptake by SGLT1 and SGLT2.
