  Design, synthesis and binding affinities of novel non-peptide mimics of somatostatin/sandostatin®

  摘要：

  Based on molecular modelling studies of Sandostatin(R), sugar-based derivatives I-VI were prepared as potential non-peptide mimics of somatostatin/Sandostatin(R). These compounds displaced 3-[I-125]-Tyr(11)-SRIF-14 from the somatostatin receptor on membranes of rat cerebral cortex with IC50 values between 10 and 15 mu M.

  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。

  Isomerization of enantiopure C2-symmetric 3,5-dihydroxyazepane derivatives has been studied. The neighboring nitrogen participation occurs during mesylation to give a chloromethylpiperidine, whereas from the a chiral bridged morpholine structure (1R-(6endo, 7exo)-8-oxa-3-azabicyclo[3.2.1]octane-6,7-diol) is obtained under Mitsunobu conditions.

• Syntheses and Evaluation as Glycosidase Inhibitor of 1,5-Dideoxy-1,5-imino-D-glucitol Analogs of Salacinol, a Potent α-Glucosidase Inhibitor Isolated from Ayurvedic Medicine, Salacia reticulata

  日期：——

  N-Alkylated deoxynojirimycin (10) bearing the same alkyl chain as salacinol (1), a potent alpha-glucosidase inhibitor isolated from Ayurvedic traditional medicine, Salacia reticulata, was found to inhibit both rat intestinal maltase and sucrase as strong as 1, while 10 has been reported to be inactive against glucoamylase G2 from Aspergillus niger. Its O-desulfate (12) was also found active against these enzymes, and characteristic sulfate anion moiety of I was found not essential for the alpha-glucosidase inhibitory activity.
