The synthesis of tetrazoles derived from D-manno and D-rhamnopyranose from L-gulonolactone and of L-rhamnopyranose from D-gulonolactone is described. These and other materials are assessed as inhibitors of glycosidases. The [4.3.0] tetrazoles of D-manno- and D-rhamnopyranose are inhibitors of human liver α-mannosidase. In contrast the D-furanose analogues show no inhibitory activity whilst the [3.3
描述了衍生自L-古洛内酯的D-甘露糖和D-鼠李吡喃糖的四唑和衍生自D-古洛内酯的L-鼠李吡喃糖的合成。这些和其他材料被评估为糖苷酶的抑制剂。D-甘露糖吡喃糖和D-鼠李糖吡喃糖的[4.3.0]四唑是人肝脏α-甘露糖苷酶的抑制剂。相反,D-呋喃糖类似物没有抑制活性,而[3.3.0] L-鼠李糖呋喃替硝唑是有效的鼠李糖苷酶抑制剂,是分枝杆菌细胞壁生物合成的潜在抑制剂,因此可以提供治疗结核病的策略。
