Problems solved by technology

Considering that many chiral mixture drugs in the prior art have potential problems such as easy to produce unknown toxic and side effects, reduced drug efficacy and difficulty in quality control, it will greatly increase the risk of research and development, and optically pure stereoisomers have more advantages than chiral mixtures. The advantages of safer, lower probability of toxic side effects, better stability and easier quality control, and optically pure stereoisomers also have potential improvements in pharmacodynamics, pharmacokinetics and toxicology Therefore, the development of a single stereoisomer with high selectivity, fast onset, high efficiency, safety, and good stability for SGLT-2 is of great significance for subsequent drug development and quality control in drug production after marketing
