  Synthesis of Glycosyl Glycerols and Related Glycolipids

  摘要：

  Several isomeric glycosyl glycerols were synthesized. Acetylated allyl glycosides of D-glucose and D-galactose were transformed into 1-O-(glycopyranosyl)-rac-glycerols in a three step procedure via the corresponding 2,3-epoxypropyl glycosides and the peracetylated glycosyl glycerols. Tetra-O-benzyl-D-glucose was glycosylated with 1,3-di-O-benzylglycerol to give the alpha-anomer preferentially. The 2-O-(tetra-O-acetyl-beta-glycopyranosyl)-sn-glycerols and 2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding alpha-derivatives of D-mannose were synthesized by selective glycosylation methods from 1,3-di-O-benzylglycerol and 1,3-O-benzylideneglycerol, respectively, and activated sugar compounds followed by hydrogenolysis. After long chain acylation and selective deacetylation the 1,3-di-O-acyl-2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding a-derivative of D-mannose were synthesized.

  N-Oxyamides of bioactive anionic glycoglycerolipids based on 2-O-β-D-glucosylglycerol were efficiently prepared. However, the oxidation step of the primary hydroxyl group of the glucose moiety in the presence of the N-oxyamide function appeared to be a difficult task that was nevertheless conveniently achieved for the first time by employing a chemoenzymatic laccase/TEMPO procedure. The obtained N-oxyamides

  有效制备了基于2- O -β- D-葡萄糖基甘油的生物活性阴离子甘油脂的N-草酰胺。然而，在N-草酰胺官能团存在下，葡萄糖部分的伯羟基的氧化步骤似乎是一项艰巨的任务，但首次通过采用化学酶漆酶/TEMPO程序方便地实现了这一任务。与相应的生物活性酯类似，所获得的N-羟基酰胺在无血清培养基中比在完全培养基中表现出更高的对卵巢癌IGROV-1细胞增殖的抑制作用。稳定性和血清结合研究表明，在完全培养基中观察到的化合物活性降低可能主要是由于血清蛋白的结合作用，而不是糖甘油脂酰基链的水解降解。此外，无血清条件下的细胞研究结果表明，N-羟基酰胺基团可以增加甘油糖脂的抗增殖活性，而与阴离子羧基的存在无关。除 IGROV-1 之外的其他细胞系的细胞研究也支持该系列化合物对 Akt 过度激活的肿瘤细胞具有一定程度的选择性。

• Regio- and diastereoselective lipase-catalyzed preparation of acetylated 2-O-glucosylglycerols

  日期：1994.7

  2-O-(beta-D-Glucopyranosyl) glycerol and 2-O-(2',3',4',6'-tetra-O-acetyl-beta-D-glucopyranosyl)glycerol have been submitted to lipase-catalyzed acetylation using Pseudomonas cepacia (LPS) and Candida antarctica (LCA) lipases in organic solvent. The reactions involved the glycerol moiety and were highly diastereoselective: LPS yielded the (2S)-1-O-acetylderivative, while, more interestingly, LCA yielded the (2R)-1-O-acetyl-derivative; in this way the natural compound lilioside A could be obtained. Conversely, lipase-catalyzed hydrolysis of the fully acetylated 1,3-di-O-acetyl-2-O-(2',3',4',6'-tetra-O-acetyl-beta-D-glucopyranosyl)glycerol using LCA furnished the (2S)-1-O-acetyl-derivative showing the same steric preference as the reverse reaction.
