Problems solved by technology

[0003] Benzyl alogliptin has stereoisomerism. Due to the presence of the amino group at the C18 position, it produces two configurations, R and S. The commercially available strong active substance is the R configuration, and the S-isomer has also been reported. Antagonizes the activity of DDP-4, but the activity is more than 1000 times lower than that of the R configuration, and has no activity against other families

Abstract

The invention discloses a method for separating Alogliptin benzoate and an enantiomer thereof through high performance liquid chromatography. The method comprises the following steps: dissolving an Alogliptin benzoate raw material medicine containing Alogliptin benzoate and the enantiomer thereof in a dilution solution until the concentration is 0.1-2mg / mL; and separating Alogliptin benzoate and the enantiomer thereof by using a high performance liquid chromatography system adopting silica with the surface being covalently bonded with cellulose-tri(3,5-dichlorophenylcarbamate) as a stationary phase and an n-hexane, ethyl acetate, anhydrous ethanol and triethylamine mixed solution as a mobile phase, wherein the dilution solution is one selected from or a mixture composed of two or more of acetonitrile, methanol and ethanol. The method effectively realizes separation and determination of Alogliptin benzoate and the enantiomer thereof, and guarantees the effectiveness and the safety of Alogliptin benzoate products.

Description

technical field [0001] The invention relates to a method for resolving alogliptin benzoate and its enantiomers, belonging to the technical field of medicine. Background technique [0002] Alogliptin benzoate (Alogliptin benzoate) is a serine protease dipeptidyl peptidase IV (DPP-4) inhibitor developed by Takeda, Japan, which can maintain glucagon-like peptide 1 (GLP-1) and glucose It depends on the level of insulin-promoting polypeptide (GIP), promotes the secretion of insulin, and thus exerts the hypoglycemic effect. [0003] Benzyl alogliptin has stereoisomerism. Due to the presence of the amino group at the C18 position, it produces two configurations, R and S. The commercially available strong active substance is the R configuration, and the S-isomer has also been reported. Antagonizes the activity of DDP-4, but the activity is more than 1000 times lower than that of the R configuration, and has no activity against other families. In the production process, alogliptin ...
