生物活性
Kifunensine 是可从放线菌中分离得到的 I 类 α-mannosidases 有效选择性抑制剂，可阻断 α-mannosidases I 修剪糖蛋白上的甘露糖残基。Kifunensine 可抑制内质网相关蛋白降解途径。体外研究
Kifunensine, an alkaloid from actinomycete Kitasatosporia kifunense 9482, is the most efficient nhibitor of a-mannosidase I, blocking N-glycan synthesis at an8GlcNAc 2 (Man8) or Man9GlcNAc 2 (Man9) stage.
RT-PCR.
| Cell Line: | Hybridoma cells expressing a human IgG1 monoclonal Antibody [3] . |
| Concentration: | 2 μg/mL. |
| Incubation Time: | 4 days. |
| Result: |
Significantly reduced the lentil lectin binding.
Kifunensine is the most effective among the inhibitors tested in producing antibodies containing oligomannose residues without fucose. |
体内研究
