| Description: | The following method was used to determine the inhibitory activity of the compounds of the present invention on SGLT1 and SGLT2. The experimental method is summarized as follows:SGLT1 and SGLT2 transiently transferred HEK293 cells were seeded in a 96-well plate. The density of the cells was 1-1.5×104. The cells were cultured at 37° C. and 5% CO2 for 48 hours, and then washed twice with 200 μL sodium-free buffer. 90 μL sodium-containing buffer of the test compound at different concentrations was added to the well. Each test compound was repeated in three wells for each concentration. The cells were cultured at 37° C. for 15 minutes, then 10 μL (in number 0.1 μCi [14C]) Methyl α-D-glucopyranoside was added to each well of the 96-well plate. The cells were further cultured at 37° C. for 2 hours, then the supernatant was discarded. The cells were washed twice with pre-chilled sodium-free buffer and then dissolved in 100 μL NaOH (200 mM). 100 μL scintillation solution was added, and mixed well. Scintiloscope was used for the quantitative detection of 14C. |
