[0083] (3R,4S,5S,6R)-2-{3-[(5-(4-Fluorophenyl)selenophen-2-yl)methyl]-4-methylphenyl}-6-hydroxymethyl -2-Methoxytetrahydro-2H-pyran-3,4,5-triol (7) and (2S,3R,4R,5S,6R)-2-{3-{[5-(4- Fluorophenyl)selenophen-2-yl]methyl}-4-methylphenyl}-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (10) synthesis
[0084]
[0085] Step A: D-gluconolactone (5.0g, 28.1mmol) and N-methylmorpholine (23.3g, 222mmol) were dissolved in THF (50mL), and trimethylchlorosilane (18.3 g, 168 mmol). Stirring was continued at this temperature for 1 hour after the addition was complete, and then the mixture was naturally warmed to room temperature and stirred overnight. Toluene (200 mL) was added, and ice water (200 mL) was added dropwise under an ice-water bath to control the inner temperature not to exceed 10°C. Separate the layers, collect the organic layer, and extract the aqueous layer with toluene (50 mL). The combined organic layers were washed successively with saturated aqueous sodium dihydr...

Abstract
The invention discloses novel SGLT2 inhibitor compounds shown in a formula (I), pharmaceutically acceptable salts, easily hydrolyzed pre-drug esters or isomers and a pharmaceutical composition which contains the compounds as an inhibitor of a sodium-glucose co-transporter (SGLT). The pharmaceutical composition is used for treating or delaying related diseases such as diabetes, diabetic retinopathy, diabetic neuropathy, diabetic nephropathy, insulin resistance, hyperglycemia, hyperinsulinemia, rise of fatty acid or glycerinum, hyperlipemia, obesity, hypertriglyceridemia, X syndrome, diabetic complications, atherosclerosis, hypertension and the like. The formula is shown in the description.
Description
technical field [0001] The present invention relates to a compound represented by general formula (I) and general formula (II), its pharmaceutically acceptable salt, its easily hydrolyzed prodrug ester or its isomer, and a pharmaceutical composition containing the compound , and its use as a therapeutic agent, in particular as an inhibitor of the sodium-glucose cotransporter SGLT2. Background technique [0002] Diabetes is a metabolic disorder syndrome characterized by hyperglycemia caused by defects in insulinsecretion and / or insufficient insulin action. Long-term hyperglycemia can damage many organs, leading to dysfunction and serious complications, such as diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy. Diabetes can be divided into two types: insulin-dependent type 1 and non-insulin-dependent type 2, of which type 2 diabetes is the most common, accounting for more than 90% of diabetic patients. Diabetes has become the most prevalent disease in the ...
