产品介绍
Canagliflozin hemihydrate (also known as TA-7284; JNJ-24831754ZAE; JNJ 28431754AAA; JNJ-28431754; Invokana), the hemihydrated form of Canagliflozin, is a highly potent and selective SGLT2 inhibitor with anti-diabetic effects. It inhibits hSGLT2 with IC50 of 2.2 nM in a cell-free assay. Canagliflozin exhibits 413-fold selectivity over hSGLT1. Canagliflozin is a FDA approved drug for the treatment of type 2 diabetes. Canagliflozin is an inhibitor of subtype 2 sodium-glucose transport protein (SGLT2), which is responsible for at least 90% of the glucose reabsorption in the kidney. Blocking this transporter causes blood glucose to be eliminated through the urine. Canagliflozin was approved by the FDA on March 29, 2013, and became the first SGLT2 inhibitor approved in the USA.

实验参考方法
In Vitro

In vitro activity: Canagliflozin is a novel C-glucoside with thiophene ring. Canagliflozin inhibits Na+-dependent 14C-AMG uptake in a concentration-dependent fashion. Canagliflozin inhibits 14C-AMG uptake in CHO-hSGLT1 and mSGLT1 cells with IC50 of 0.7 μM and>1 μM, respectively. Canagliflozin inhibits the facilitative (non-Na+-linked) GLUT-mediated 2H-2-DG uptake in L6 myoblasts by less than 50%. In sham-injected oocytes, Canagliflozin (10 μM) or phlorizin (3 mM) alone in the presence of 50 μM DNJ does not affect currents. In SGLT3-injected oocytes, DMSO and Canagliflozin 10 μM inhibits DNJ-induced currents by 15.6% and 23.4%, respectively.


Kinase Assay: Canagliflozin is a highly potent and selective SGLT2 inhibitor for hSGLT2 with IC50 of 2.2 nM, and exhibits 413-fold selectivity over hSGLT1.


Cell Assay: Cells from the rat skeletal muscle cell line, L6, is used to test the effect of Canagliflozin on glucose transporter 1 (GLUT1) activity. Cells are maintained in Dulbecco's modified Eagle's medium containing 5.6 mM glucose supplemented with 10% fetal bovine serum, are seeded in 24-well plates at a density of 3 × 105 cells/well and cultured for 24 hours in an atmosphere of 5% CO2 at 37 °C. Cells are rinsed twice with Kreb's ringer phosphate HEPES buffer (pH 7.4, 150 mM NaCl, 5 mM KCl, 1.25 mM MgSO4, 1.25 mM CaCl2, 2.9 mM Na2HPO4, 10 mM HEPES) and are pre-incubated with the solutions of Canagliflozin (250 μL, 10 μM) for 5 minutes at room temperature. The transport reaction is initiated by adding 50 μL of 4.5 mM 2-DG (a substrate for GLUTs)/3H-2-DG (0.625 μCi) followed by incubation for 15 minutes at room temperature. The 2-DG uptake is halted by aspiration of the incubation mixture. Cells are immediately washed 3 times with ice-cold PBS. Samples are extracted with 0.3 N NaOH, and radioactivity is determined by liquid scintillation.

In VivoCanagliflozin shows pronounced anti-hyperglycemic effects in high-fat diet fed KK (HF-KK) mice. Oral administration at 30 mg/kg of Canagliflozin to male SD rats induces glucose excretion over 24 hours by 3,696 mg per 200 g body weight. Pharmacokinetic studies reveals a much higher exposure of Canagliflozin following oral administration. Following intravenous and oral doses of 3 and 10 mg/kg, respectively, to male SD rats, AUC0–inf, po, t1/2 and oral bioavailability are determined to be 35,980 ng·h/mL, 5.2 hours, and 85%, respectively. Thus, inhibition of SGLT2 in renal tubules after oral dosing of Canagliflozin is likely to continuously suppress reabsorption of glucose. The extensive UGE would reflect excellent pharmacokinetic properties of Canagliflozin in vivo as well as high potency of SGLT2 inhibition. Since most of the filtered glucose is reabsorbed by SGLT2 in the renal tubules, the novel compound would be useful for an anti-diabetic agent. Single oral administration of Canagliflozin at 3 mg/kg remarkably reduced blood glucose levels without influencing food intake in hyperglycemic high-fat diet fed KK (HF-KK) mice. There is a 48% reduction in blood glucose level versus vehicle at 6 hours. In contrast, Canagliflozin only slightly affects blood glucose levels in normoglycemic mice. Therefore, Canagliflozin would control hyperglycemia in the therapy of T2DM with low risk of hypoglycemia.
