A synthetic approach to 1,4-imino-L-lyxitols with various modifications at the C-5 position is reported. These imino-L-lyxitol cores were used for the preparation of a series of N-(4-halobenzyl)polyhydroxypyrrolidines. An impact of the C-5 modification on the inhibition and selectivity against GH38 α-mannosidases from Drosophila melanogaster, the Golgi (GMIIb) and lysosomal (LManII) mannosidases and
报道了在C-5位具有各种修饰的1,4-亚氨基-L-糖醇的合成方法。这些亚氨基-L-木糖醇核用于制备一系列N-(4-卤代苄基)聚羟基吡咯烷。评估了C-5修饰对黑腹果蝇,高尔基(GMIIb)和溶酶体(LManII)甘露糖苷酶和商业化的加拿大豆(Canavalia ensiformis)的杰克豆α-甘露糖苷酶对GH38α-甘露糖苷酶的抑制和选择性的影响。C-5处的修饰影响了它们对靶GMIIb酶的抑制活性。相反,未观察到吡咯烷对LManII的抑制作用。因此,亚氨基-L-糖醇核心的修饰是用于设计具有对靶GMIIb酶的期望选择性的抑制剂的合适基序。
