  名称：

  5-epi-Deoxyrhamnojirimycin is a potent inhibitor of an α-l-rhamnosidase: 5-epi-deoxymannojirimycin is not a potent inhibitor of an α-d-mannosidase

  摘要：

  Whereas deoxyrhamnojirimycin (LRJ) 1 shows no significant inhibition of naringinase (an alpha-L-rhamnosidase), its C-5 epimer 2 is a potent and specific inhibitor of the enzyme and demonstrates the value of unambiguous chemical synthesis of such materials in the evaluation of their biological properties. In contrast, moderately weak inhibition towards an alpha-D-mannosidase is shown by both deoxymannojirimycin (DMJ) 5 and its C-5 epimer 6. Mimics of L-rhamnose which are recognised by enzymes that synthesise or process L-rhamnose may inhibit el ther the biosynthesis of the sugar or its incorporation into mycobacterial cell walls, providing new strategies for the treatment of diseases such as tuberculosis and leprosy. Molecular modelling studies provide a rationale for the surprisingly potent activity of the C-S epimer 2 compared with LRJ 1 and support a general hypothesis that potent piperidine glycosidase inhibitors mimic the H-4(3) conformation Of the relevant glycopyranosyl cation intermediate.

  L-鼠李糖的哌啶类似物对柚皮苷酶（L-鼠李糖苷酶）的抑制作用：用于包含三羟基哌酸的文库的支架

  摘要：

  L-Deoxyrhamnojirimycin 1不能显着抑制柚皮苷酶，但是5- epi -L-deoxyrhamnojirimycin 2是有效的抑制剂。相反，α-C-糖苷1是L-鼠李糖苷酶的良好抑制剂，而这些的2则不是。中间的氮杂双环内酯可能用于将许多三羟基哌酸掺入肽文库中。
