  Synthesis of all stereoisomers of 3-hydroxypipecolic acid and 3-hydroxy-4,5-dehydropipecolic acid and their evaluation as glycosidase inhibitors

  摘要：

  A highly practicable synthesis of both enantiomers of 3-hydroxypipecolic acid derivatives 1, 2, 3, 4 is described. Screening of these molecules for glycosidase inhibition has been examined. Compound 3 was shown to be a potent inhibitor of beta-N-acetylglucosaminidase as well as Escherichia coli beta-glucuronidase. (C) 2008 Elsevier Ltd. All rights reserved.

  kinetic resolution, the synthesis of both L- and D-isomers of 3,4,5-trihydroxy- and 3-hydroxypipecolic acids was achieved. None of the compounds tested showed inhibitory activity against alpha- and beta-glucosidases. On the other hand, L-23 and L-29 were found to have potent inhibitory activity against beta-glucuronidase. In addition, it is interesting that some uronic-type azasugar derivatives showed moderate

  我们已经合成了对应于糖醛酸的5-氮杂衍生物的3-羟基-和3,4,5-三羟基哌酸衍生物，并评估了它们对包括β-葡萄糖醛酸苷酶在内的各种糖苷酶的抑制活性。选择化合物4和5作为合成3,4,5-三羟基哌酸和3-羟基哌酸以及3-羟基贝白蛋白（从有毒蘑菇中分离出的独特天然产物）的常用中间体。N-Boc-烯丙基甘氨酸衍生物与丙烯醛的交叉羟醛缩合反应，然后进行闭环易位，得到非对映异构体混合物的4和5，可以通过硅胶柱色谱法分离。通过使用脂肪酶催化的动力学拆分，可以合成3,4,5-三羟基和3-羟基哌酸的L-异构体和D-异构体。所测试的化合物均未显示出对α-和β-葡糖苷酶的抑制活性。另一方面，发现L-23和L-29对β-葡糖醛酸糖苷酶具有有效的抑制活性。另外，有趣的是，一些糖醛酸型的氮杂糖衍生物显示出对β-N-乙酰氨基葡糖苷酶的中等抑制活性。
