Introduction of alkyl or alkoxy substituents at the 4′-position was found to improve SGLT2 potency, whereas introduction of a hydrophilic group at this position was deleterious. Compounds with alkoxy-, cycloalkoxy- or cycloalkenyloxy-ethoxy scaffolds exhibited good inhibitory activity and high selectivity toward SGLT2. Selected compounds were investigated for in vivo efficacy.
已经合成了一系列在远端芳基环的4'-位置具有各种取代基的C-芳基
葡糖苷,并评估了其对hSGLT1和hSGLT2的抑制作用。发现在4'-位置处引入烷基或烷氧基取代基可提高SGLT2的效力,而在该位置处引入亲
水性基团是有害的。具有烷氧基-,环烷氧基-或环烯氧基-乙氧基支架的化合物表现出良好的抑制活性和对SGLT2的高选择性。研究了所选化合物的体内功效。
