Tofogliflozin hydrate (CSG-452 hydrate) 是一种有效的,高度特异性的和选择性的SGLT2抑制剂,其IC50值为 2.9 nM,对人、大鼠和小鼠SGLT2的Ki值分别为 2.9 nM,14.9 nM 和 6.4 nM。Tofogliflozin hydrate 部分抑制肾小管细胞中高葡萄糖诱导的ROS生成。
生物活性 | Tofogliflozin hydrate (CSG-452 hydrate) is a potent and highly specificsodium/glucose cotransporter 2 (SGLT2)inhibitor with anIC50of 2.9 nM andKivalues of 2.9 nM, 14.9 nM, and 6.4 nM for human, rat, and mouseSGLT2[1]. Tofogliflozin partially inhibits high glucose-inducedreactive oxyen species (ROS)generation in tubular cells[2]. |
IC50& Target | IC50: 2.9 nM (SGLT2); Ki: 2.9 nM ( humanSGLT2), 14.9 nM (ratSGLT2), and 6.4 nM (mouseSGLT2)[1] |
体外研究 (In Vitro) | Tofofloxacin (3-30 nM; 24 hours; tubular epithelial cells) treatment inhibits the oxidative stress generation and monocyte chemoattractant protein-1 (MCP-1) gene expression in tubular cells induced by high glucose[2]. Tofofloxacin (3-30 nM; 8 days; tubular epithelial cells) treatment inhibits the apoptotic cell death induced by high glucose[2].
RT-PCR[2] Cell Line: | Tubular epithelial cells | Concentration: | 3 nM and 30 nM | Incubation Time: | 24 hours | Result: | Inhibited MCP-1 gene expression in tubular cells induced by high glucose exposure. |
Apoptosis Analysis[2] Cell Line: | Tubular epithelial cells | Concentration: | 3 nM and 30 nM | Incubation Time: | 8 days | Result: | Inhibited the apoptotic cell death induced by high glucose. |
|
体内研究 (In Vivo) | Tofogliflozin (0.1-10 mg/kg; oral administration; once daily; for 4 weeks;db/dbmice) treatment improves hyperglycemia and thereby ameliorated glucose intolerance of the obese diabetic mice[1].
Animal Model: | db/dbmice[1] | Dosage: | 0.1 mg/kg, 0.3 mg/kg, 1 mg/kg, 3 mg/kg, or 10 mg/kg | Administration: | Oral administration; once daily; for 4 weeks | Result: | Observed acute blood glucose reduction, dose-dependently reduced glycated hemoglobin, significantly prevented the decrease of IRI levels at doses of 3 and 10 mg/kg, and no difference in food intake or body weight. |
