(2S,3R,4R,5S,6R)-2-Aryl-5,5-difluoro-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4-diols and (2S,3R,4R,5S,6R)-2-aryl-5-fluoro-5-methyl-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4-diols were discovered as dual inhibitors of sodium glucose co-transporter proteins (e.g. SGLT1 and SGLT2) through rational drug design, efficient synthesis, and in vitro and in vivo evaluation. Compound 6g demonstrated potent dual inhibitory activities (IC50 = 96 nM for SGLT1 and IC50 = 1.3 nM for SGLT2). It showed robust inhibition of blood glucose excursion in an oral glucose tolerance test (OGTT) in Sprague Dawley (SD) rats when dosed at both 1 mg/kg and 10 mg/kg orally. It also demonstrated postprandial glucose control in db/db mice when dosed orally at 10 mg/kg.

-二醇通过合理药物设计、高效合成以及体内外评估被发现为
钠葡萄糖协同转运蛋白(如SGLT1和SGLT2)的双重
抑制剂。化合物6g表现出强大的双重抑制活性(SGLT1的IC50为96 nM,SGLT2的IC50为1.3 nM)。在给予1 mg/kg和10 mg/kg剂量时,它在斯佩格雷-道利(
SD)大鼠的
口服葡萄糖耐量试验(OG
TT)中显示出对血糖 excursion的强效抑制作用。在给予10 mg/kg口服剂量时,它还在db/db小鼠中表现出对餐后血糖的控制作用。
