The invention relates to the field of medicine related to diabetes, in particular to an SGLT2 inhibitor shown in the specification and containing a nitrile-based benzene S-glucoside structure, a preparation method of the inhibitor and application of the compound in the diabetes medicine preparation process.

Description

Compound of a kind of nitrile group-containing benzene S-glucoside structure and uses thereof
Technical field
The present invention relates to the pharmaceutical field relevant to diabetes B.Specifically, the present invention relates to 2 type sodium dependent glucose transhipment (SGLT2) inhibitor, the Preparation method and uses to the medicative a kind of nitrile group-containing benzene S-glucoside structure of diabetes B.
Background technology
Whole world diabetic subject presents the trend increased gradually, and wherein about the overwhelming majority is diabetes B patient.Sulfonylurea, N1,N1-Dimethylbiguanide class, thiazolidinediones, alpha-glucosidase inhibitor class, dipeptidyl peptidase-iv inhibitor class and trypsin class medicine is mainly contained at present at the antidiabetic medicine of Clinical practice.These medicines have good therapeutic action, but long-term treatment exists comparatively severe side effect; And owing to there is resistance, in some cases in time drug combination be all difficult to the blood sugar controlling patient.
2 type sodium dependent glucoses transhipment (SGLT2) are the novel targets of the treatment diabetes of discovered in recent years.SGLT2 is mainly distributed in renal proximal tubules, and its effect absorbs the glucose in urine, and returns it in blood, therefore suppresses that SGLT2's just can reduce the concentration of glucose in blood.When SGLT2 function is suppressed, more glucose will be secreted from urine, this glucose level that will contribute to diabetic subject and keep correct.
