Nine new compounds having five- and modified six-member carbohydrate core derived from D-lyxose or D-mannose, and non-hydrolysable aglycones (benzylsulfonyl or aryl(alkyl)triazolyl) were synthesised to investigate their ability to inhibit the recombinant Drosophila melanogaster homologs of two human GH38 family enzymes: Golgi mannosidase II (dGMIIb) and lysosomal mannosidase (dLMII). Two compounds
合成了九种新化合物,这些化合物具有衍生自D-lyxose或D-甘露糖的五元和六元碳水化合物核心,以及不可水解的糖苷配基(苄基磺酰基或芳基(烷基)三唑基),以研究其抑制重组果蝇果蝇同系物的能力。两种人类GH38家族酶中的一种:高尔基甘露糖苷酶II(dGMIIb)和溶酶体甘露糖苷酶(dLMII)。两种化合物是弱选择性dGMIIb抑制剂,在mM水平下显示IC50。此外,发现另一种GH38酶,商品菜豆α-甘露糖苷酶,无论碳水化合物核心如何,都被三唑缀合物抑制,而相应的砜是无活性的。
