  Design and Synthesis of Activity Probes for Glycosidases

  摘要：

  [GRAPHICS]A new synthetic route was developed for the preparation of activity probe 1 for beta-glucosidase in this study. The key glycosidation step begins with benzyl p-hydroxyphenylacetate. Benzylic functionalization for the construction of the trapping device was achieved at later stages. Probe 1 was shown to be able to label the target enzyme. This cassette-like design offers great flexibility for future alterations. It would allow the synthetic scheme to expand to other glycosidase probes with different linker/reporter combinations.

  syntheses were performed for the preparation of a library based on the structure of a key intermediate. The recognition head of this library covers a series of six sugars, including alpha- and beta-d-Glc, alpha- and beta-d-Gal, alpha-d-Man, and alpha-l-Fuc. Each member in this versatile intermediate library could serve as the building block in constructing an activity probe for GHs. As demonstrated in this

  已经证明，选择性标记糖苷水解酶（GH）亚家族的化学探针是GH相关研究的有力工具。我们先前已经在模型研究中证明了采用盒式设计的β-葡萄糖苷酶活性探针的设计和合成。在本文中，我们报道了使用（4-羟苯基）乙酸2-氰基乙基酯作为潜伏捕集装置的前体的改进的合成路线。基于关键中间体的结构，进行平行合成以制备文库。该库的识别头涵盖了一系列的六种糖，包括α-和β-d-Glc，α-和β-d-Gal，α-d-Man和α-1-Fuc。这个通用的中间库中的每个成员都可以作为构建GH活性探针的基础。如本研究所示，
