A series of iso-allo-DNJ and L-isoDALDP derivatives were synthesized from dithioacetal 16 with sequential and highly diastereoselective Ho and Henry reactions, and aziridinium intermediate-mediated ring rearrangement as key steps. Glycosidase inhibition assay found four of them as selective α-glucosidase inhibitors, and the less substituted compound 30 showed more potent α-glucosidase inhibition (IC50
一系列异异-DNJ 和L -isoDALDP 衍生物由二硫缩醛16合成,具有连续和高度非对映选择性的 Ho 和 Henry 反应,以及氮丙啶中间体介导的环重排作为关键步骤。糖苷酶抑制试验发现其中四种是选择性 α-葡萄糖苷酶抑制剂,取代较少的化合物30显示出比其他化合物更强的 α-葡萄糖苷酶抑制作用 (IC 50 = 9.3 μM)。分子对接研究揭示了 iso- allo -DNJ 和L -isoDALDP 衍生物与其母体化合物的不同对接模式,以及化合物30与 isofagomine 的相似性。
