spiro-cyclization of the corresponding glucosyl-hydroximothioates. In an effort to synthesize analogous glucopyranosylidene-spiro-1,2,4-oxadiazolines, with a nitrogen atom instead of the sulphur, attempted cyclizations resulted in aromatization of the heterocycle with opening of the pyranosyl ring. Enzymatic measurements showed that some of the glucose-based inhibitors were active in the micromolar range. The
通过NBS介导的相应的葡糖基-羟肟基硫代酸酯的螺环化,可以高收率制备葡糖基亚烷基-螺-1,4,2-氧杂噻唑。为了合成具有氮原子而不是硫原子的类似的吡喃吡喃基-螺-1,2,4-恶二唑啉,尝试的环化导致杂环的芳构化并带有吡喃糖基环。酶促测量表明,一些基于葡萄糖的抑制剂在微摩尔范围内具有活性。在 迄今为止已知的基于葡萄糖的抑制剂中,2-萘基取代的1,4,2-氧杂噻唑显示出对RMGPb的最佳抑制作用(K i = 160 nM)。
