KGA-2727是选择性，高亲和力和口服有效的SGLT1抑制剂，对人和大鼠SGLT1的Ki分别为 97.4 nM 和 43.5 nM，对SGLT1的选择性比人SGLT2 高 140 倍 ，大鼠SGLT2高390 倍。KGA-2727具有抗糖尿病活性。

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.
