| | SGLT1/2 in-vitro assay |
| Description: | To analyze a sodium-dependent glucose transport, cells for expressing hSGLT1 and hSGLT2 were seeded at 1×105 cells per well into a 96-well culture plate, after which resulting cells were cultured in an RPMI 1640 medium containing 10% fetal bovine serum (FBS). In 1 day after culture, the resulting cells were cultured in a pre-treatment buffer solution (10 mM HEPES, 5 mM tris, 140 mM choline chloride, 2 mM KCl, 1 mM CaCl2 and 1 mM MgCl2, pH 7.4) under 37° C./5% CO2 conditions for 10 minutes. Then, the resulting cells were cultured in a uptake buffer solution (10 mM HEPES, 5 mM tris, 140 mM NaCl, 2 mM KCl, 1 mM CaCl2, 1 mM MgCl2 and 1 mM AMGS pH 7.4) containing 14C-AMG (8 μM) and a compound of the present disclosure or a dimethyl sulfoxide (DMSO) vehicle under 37° C./5% CO2 conditions for 2 hours. After culture, the cells were washed twice with a washing buffer solution (a pre-treatment buffer solution containing 10 mM AMG at room temperature), after which a radiation thereof was measured by using a liquid scintillation counter. IC50 of each compound was measured according to a non-linear regression analysis by using SigmaPlot (Document Analytical Biochemistry 429: 70-75, Molecular and Cellular Biochemistry 280: 91-98, 2005). |
