Homogeneous suspension

CMC-NA

≥5mg/ml

Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Tofogliflozin (CSG 452) is a novel sodium-glucose co-transporter 2(SGLT2) inhibitor with IC50 values of 2.9 nM and 8444 nM for hSGLT2 and Hsglt1, respectively.
in vitro	Tofogliflozin (CSG 452) is the potent and most selective inhibitor of SGLT2; the selectivity of this compound toward SGLT2 is 2900 times that toward SGLT1. It dose-dependently inhibited glucose entry into tubular cells, suppressed high glucose-induced ROS generation, MCP-1 gene induction and apoptosis in tubular cells, and an antioxidant NAC mimicked its effects on high glucose-exposed tubular cells^[3].
in vivo	A single oral administration of Tofogliflozin (CSG 452) lowers blood glucose levels in Zucker diabetic rats with increased renal glucose clearance and treatment for 4 weeks with this compound improves glucose tolerance in db/db mice. It lowers urine volume compared with the untreated control group at 8 weeks of treatment. This compound increases renal glucose clearance levels compared with untreated db/db mice, whereas losartan treatment has no effect on this parameter. It reduces the threshold of glucose reabsorption in db/db mice and increases the UGE, and then reduces the PG. Tofogliflozin treatment significantly and dose-dependently elevates the total beta-cell mass, suggesting that beta-cell loss is prevented. It suppresses plasma glucose and glycated Hb and preserves pancreatic beta-cell mass and plasma insulin levels^[2].

	実験の流れ	Tubular cells are treated with or without 3 nM or 30 nM tofogliflozin (CSG 452) under serum-free BM containing 10 μg/ml transferrin and GA-1 000 for 24 h at 37 °C. After washing with PBS, the cells are incubated with Hanks’ balanced salt solution (HBSS) containing 100 μM of 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-d-glucose (2-NBDG), a fluorescent derivative of glucose, in the absence of this compound for 15 min. Culture medium is removed and replaced with HBSS, and fluorescence intensity in the cells is analyzed in an ARVO fluorescent plate reader.
