were synthesized from readily available 1,2:5,6-di-O-isopropylidene-α-glucofuranose through an ene-yne metathesis as the key step. The glycosidase inhibition activity of these compounds against some commercially available enzymes was examined, and the analogues were found to be very selective glycosidase inhibitors at concentrations in the range of 21–44 μM.
两种基于多羟基哌啶的 2-C-羟甲基支链的 L-1-脱氧异菌野尻霉素 (L-allo-DNJ) 类似物由现成的 1,2:5,6-二-O-异亚丙基-α-呋喃糖通过烯-炔复分解是关键步骤。检查了这些化合物对一些市售酶的糖苷酶抑制活性,发现类似物在 21–44 μM 的浓度范围内是非常有选择性的糖苷酶抑制剂。
