Embodiment 1
[0028] The synthetic method of embodiment 1N-(2-(4-chlorobenzoyl) phenyl)-5-bromothiophene-2-carboxamide Y1
[0029] Add 5-bromo-2-thiophenecarboxylic acid (1mmol, 206mg), 3mL thionyl chloride, and 3 drops of pyridine into a 50mL round-bottomed flask, stir and add flow (80°C), after 2 hours, stop the reaction and rotate The solvent was removed by evaporation to obtain 5-bromo-2-thienyl chloride, which was added to 5 mL of dry dichloromethane for later use. Add 2-amino-4'-chlorobenzophenone (1 mmol, 232 mg), 5 mL of dichloromethane, and 1 mL of triethylamine into a 50 mL round bottom flask, stir to dissolve, and cool to 0° C. in an ice-water bath. Under stirring, a dichloromethane solution of 5-bromo-2-thiophene acid chloride was added dropwise (dropped within 10 minutes), and after the dropwise addition was completed, the stirring reaction was continued for 2 hours. Stop the reaction, remove the solvent under reduced pressure with a rotary evaporator, and separate and purify ...
Embodiment 2
[0031] Example 2 Detection of insulin secretion-stimulating activity of N-(2-(4-chlorobenzoyl)phenyl)-5-bromothiophene-2-carboxamide Y1
[0032] Insulin-stimulating activity was detected by rat insulinoma cells INS-832 / 13 cells. INS-832 / 13 cells were cultured in RPMI1640 medium containing 10% fetal bovine serum, 10mM hydroxyethylpiperazine ethanesulfonic acid, 2mM L-glutamate, 1mM sodium pyruvate, 0.05mM mercaptoethanol, placed Contains 5% CO 2 cultured in a cell culture incubator.
[0033] INS-832 / 13 cells take 10 5 Plate / well in 24-well plate, 37°C, 5% CO 2 Incubate for 48 hours. When the cells grow well, suck out the RPMI1640 medium, add sugar-free buffer solution (115mM sodium chloride, 5mM potassium chloride, 24mM sodium bicarbonate, 2.5mM calcium chloride, 1mM magnesium chloride, 10mM hydroxyethylpiperazine ethylsulfur acid, 0.1% bovine serum albumin, pH7.2) for 2 hours, and then replaced with buffer solutions containing 2.5mM and 16.7mM glucose concentrations and 1...
