Biological Activity

Description Ipragliflozin (ASP1941) is a highly selective sodium-glucose cotransporter 2 (SGLT2) inhibitor with an IC50 value of 7.4 nM for hSGLT2 and a 254-fold selectivity versus SGLT1.

In vitro

Ipragliflozin concentration-dependently inhibits mouse, rat, and human SGLT2 activity at nanomolar concentrations. Furthermore, ipragliflozin does not potently inhibit human SGLT4 and SGLT5 isoforms (IC50>1,000 nM). In addition, ipragliflozin does not inhibit several glucose transporter (GLUT) isoforms, including GLUT1 and GLUT4, in mouse 3T3-L1, rat L6, human Caco-2, and HepG2 cells (IC50>1,000 nM). Ipragliflozin does not interact with various receptors, ion channels, and transporters such as adrenergic (α1, α2, and β), muscarinic (M1, M2, and non-selective), angiotensin(AT1 and AT2), calcium channel (L-type and N-type), potassium channel (KATP and SKCa), sodium channel (site 2), cholecystokinin (CCKA and CCKB), dopamine (D1, D2, and transporter), endothelin (ETA and ETB), gamma-aminobutyric acid (GABAA and GABAB), glutamate (AMPA, kainate, and NMDA), serotonin (5-HT1, 5HT2B, and transporter), histamine (H1, H2, and H3), and neurokinin (NK1, NK2, and NK3), exhibiting IC50 values >3,000 nM. Ipragliflozi is stable against mouse intestinal glucosidases[2].

In vivo Single oral doses (0.01-10 mg/kg) of ipragliflozin induces urinary glucose excretion in a dose-dependent manner in both normal and in KK-Ay mice, a type 2 diabetes model. Single administrations of ipragliflozin (0.1, 0.3 and 1 mg/kg) dose-dependently reduces blood glucose level in both KK-Ay mice and STZ rats. Administration of a single 0.3 mg/kg dose intravenously and a single 1 mg/kg dose orally to rats reveal that ipragliflozin has good bioavailability with a value of 71.7%[1]. Ipragliflozin shows good pharmacokinetic properties following oral dosing, and dose-dependently increased urinary glucose excretion, which lasts for over 12 h in normal mice. Single administration of ipragliflozin results in dose-dependent and sustained antihyperglycemic effects in both diabetic models. It has a low risk of hypoglycemia. After oral administration of ipragliflozin (3 mg/kg) to normal mice, plasma concentrations of ipragliflozin reach a maximum at 1 h and then gradually decrease. Obvious plasma concentrations are detected even 8 h after administration. In the pharmacokinetic studies in mice, ipragliflozin shows good oral bioavailability and exhibits high drug concentrations for long periods. The absolute bioavailabilities of ipragliflozin are 71.7-90.7% and 74.5-75.3% in rats and monkeys, respectively [2].

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
