  Synthesis of amphiphilic polyhydroxylated pyrrolidines as potential glycosidase inhibitors

  摘要：

  Several polyhydroxylated pyrrolidines with an aliphatic long chain on the ring nitrogen were prepared starting from D-mannitol. An amphiphilic bis-azasugar scaffold has been also prepared. These products behave as cationic surfactants and show a promising anti HIV-I activity. (C) 1998 Elsevier Science Ltd. All rights reserved.

  N-substituted iminosugar analogues are potent inhibitors of glucosidases and glycosyltransferases with broad therapeutic applications, such as treatment of diabetes and Gaucher disease, immunosuppressive activities, and antibacterial and antiviral effects against HIV, HPV, hepatitis C, bovine diarrhea (BVDV), Ebola (EBOV) and Marburg viruses (MARV), influenza, Zika, and dengue virus. Based on our previous work

  N-取代的亚氨基糖类似物是强力的葡糖苷酶和糖基转移酶抑制剂，具有广泛的治疗应用，例如糖尿病和高雪氏病的治疗，免疫抑制活性以及对HIV，HPV，丙型肝炎，牛腹泻（BVDV），埃博拉病毒（EBOla）的抗菌和抗病毒作用EBOV）和马尔堡病毒（MARV），流行性感冒，寨卡病毒和登革热病毒。基于我们先前在功能化异构体1,5-二氧-1,5-亚氨基-D-古洛糖醇（L-古洛哌啶，在C-2和C-5处相对于葡萄糖或脱氧野oji霉素（DNJ）呈反向构型）的研究）和N-连接到吡喃葡萄糖单元不同位点的1,6-二脱氧-1,6-亚氨基-D-甘露醇（D-甘露聚糖-庚烷衍生物）核心，我们继续对这些带有简单N-烷基链而不是葡萄糖的亚氨基糖进行研究，以了解这些容易获得的支架是否可以保留相应的基于葡萄糖的N-烷基衍生物作为miglustat和miglitol药物中的DNJ核心的抑制谱。因此，通过利用经由两个异构体双环氧化物的S
• Polyhydroxylated piperidines and azepanes from D-mannitol synthesis of 1-deoxynojirimycin and analogues
  作者：Lydie Poitout、Yves Le Merrer、Jean-Claude Depezay

  DOI：10.1016/s0040-4039(00)76888-2

  日期：1994.5

  D-mannitol and L-iditol bis-epoxides, easily obtained from D-mannitol, are convenient substrates for the synthesis of polyhydroxylated piperidines and azepanes, via a nucleophilic opening of one epoxy function followed by a spontaneous intramolecular ring closure. Using this strategy 1-deoxynojirimycin and analogues were prepared.

  可以容易地从D-甘露醇获得的D-甘露醇和L -iditol双环氧化物是通过一个环氧官能团的亲核开口随后自发的分子内环闭合而合成多羟基化哌啶和氮杂环庚烷的方便底物。使用这种策略，制备了1-脱氧野oji霉素和类似物。

  日期：1997.3

  A series of enantiomerically pure azasugars (2,5-dideoxy-2, 5-imino-D-mannitol, 1-deoxynojirimycin, 1-deoxymannojirimycin, and related compounds) was synthesized from D-mannitol via aminoheterocyclization of C2-symmetric bis-epoxides and subsequently followed by ring isomerization in few cases. These compounds have been evaluated as inhibitors of several glycosidases (alpha- and beta-D-glucosidases

  通过C2-对称双环氧化物的氨基杂环化反应，由D-甘露醇合成了一系列对映体纯的氮杂糖（2,5-dideoxy-2、5-imino-D-甘露醇，1-deoxynojirimycin，1-deoxymannojirimycin和相关化合物）。在少数情况下随后进行环异构化。这些化合物已被评估为几种糖苷酶（α-和β-D-葡糖苷酶，α-D-甘露糖苷酶和α-L-岩藻糖苷酶）的抑制剂。抑制研究显着地表明，多羟基化的氮杂环庚烷是糖苷酶的抑制剂，Ki在微摩尔范围内。

  This Letter describes an efficient synthesis of a range of 1'-homo-N-nucleoside mimetics with a series of 4-substituted 1,2,3-triazoles replacing the natural nucleobase. The synthesis of 6-O-monosulfated 1'-homo-N-nucleoside mimetic derivatives is also discussed. (C) 2011 Elsevier Ltd. All rights reserved.
