A new series of (2S,3R,4R,5S,6R)-5-fluoro-6-(hydroxymethyl)-2-aryltetrahydro-2H-pyran-3,4-diols as dual inhibitors of sodium glucose co-transporter proteins (SGLTs) were disclosed. Two methods were developed to efficiently synthesize C5-fluoro-lactones 3 and 4, which are key intermediates to the C5-fluoro-hexose based C-aryl glucosides. Compound 2b demonstrated potent hSGLT1 and hSGLT2 inhibition (IC50 = 43 nM
一系列新的(2S,3R,4R,5S,6R)-5-氟-6-(羟甲基)-2-芳基四氢-2H-吡喃-3,4-二醇作为钠葡萄糖共转运蛋白的双重抑制剂( SGLTs)。开发了两种方法以有效合成C 5-氟代内酯3和4,它们是基于C 5-氟己糖的C-芳基葡糖苷的关键中间体。化合物2b表现出有效的hSGLT1和hSGLT2抑制作用( SGLT1的IC 50 = 43 nM,SGLT2的IC 50 = 9 nM)。它在Sprague Dawley(SD)大鼠的口服葡萄糖耐量试验(OGTT)中显示出对葡萄糖偏移的强烈抑制作用,并在db / db中发挥了明显的降血糖作用 口服剂量为10 mg / kg的小鼠和高脂饮食喂养的ZDF大鼠。
