  Synthesis of α-d-Glcp-(1 → 2)-α-d-Glcp-(1 → 3)-α-d-Glcp-O-(CH2)8COOCH3 for use in the assay of α-glucosidase I activity

  摘要：

  The chemical synthesis of alpha-D-Glcp-(1 --> 2)-alpha-D-Glc p-(1 --> 3)-alpha-D-Glcp-O-(CH2)(8)COOCH3 (9), a substrate specific for cr-glucosidase I, is reported. This enzyme removes the terminal alpha-D-Glcp unit to produce alpha-D-Glcp-(1 --> 3)-alpha-D-Glcp-O-(CH2)(8)COOCH3 (10). This is the first synthetic substrate described for glucosidase I that allows kinetic evaluation of substrates and inhibitors of this enzyme. Tetramethylrhodamine was coupled to 9 through an ethylenediamine linker to produce a brilliant red derivative. Addition of this fluorescent dye did not affect enzyme binding to the substrate, as determined by a comparison of the K-m value (1.3 mM). The fluorescent label allows visual detection of 2-3 pmol of product by TLC. (C) 1996 Elsevier Science Ltd.
