    八种N-乙酰氨基葡萄糖氨基转移酶-V的氨基脱氧三糖抑制剂的合成和评价。
    摘要:
    N-乙酰氨基葡萄糖氨基转移酶-V是一种重要的酶,可控制N-连接寡糖的分支模式。该酶识别三糖辛基2-乙酰氨基-2-脱氧-β-D-吡喃葡萄糖基-(1-> 2)-α-D-甘露吡喃糖基-(1-> 6)-β-D-吡喃葡萄糖苷(5)作为底物,并将β-连接的GlcNAc残基添加到中央α-Man单元的OH-6。化学合成了8个5的类似物,其中5中的α-Man残基的C-6被脱氧,并且在相同残基的C-4处引入了结构多样的修饰。为此目的制备的关键中间体是辛基2-乙酰氨基-2-脱氧-β-D-吡喃葡萄糖基-(1-> 2)-4-氨基-4,6-二脱氧-α-D-甘露吡喃糖基-(1- -> 6)-β-D-吡喃葡萄糖苷(7a),其中原始的4'-氨基很容易在未保护的糖上衍生化。评价了八个类似物7a-7h作为GlcNAcT-V的抑制剂,它们是分离的(从仓鼠肾脏)和克隆的(从大鼠肾脏)。发现所有化合物都是Ki在3-106 micro

    This minireview covers synthetic methods towards carbasugar-containing non-glycosidically linked pseudodisaccharides or higher pseudooligosaccharides. Carbocyclic pyranose mimetics (saturated or unsaturated between C-5 and C-5a) are linked by ether, thioether or amine bridges to carbohydrates or other carbasugars.

    βGlcNAc(12)αMan(16)βGlc-O(CH2)7CH3 (4) is an acceptor specific for N-acetylglucosaminyltransferase-V (GlcNAcT-V), a branching enzyme controlling the biosynthesis of cell-surface Asn-linked oligosaccharides. Three analogs of 4, where the central mannose residue has been O-methylated at O-3, at O-6, and where the 6-OH group was replaced by fluorine, were chemically synthesized, characterized by NMR-spectroscopy

    日期:1997.6.1

    N-Acetylglucosaminyltransferase-V (GlcNAcT-V) transfers a β-linked GlcNAc residue from UDP-GlcNAc to the 6-OH group of the αMan residue in oligosaccharides terminating in the sequence β-D-GlcpNAc-(1 → 2)-α-D-Manp-(1 → 6)-β-D-Glcp-OR (5, R = (CH2)7CH3). The terminal GlcNAc moiety may be replaced by a Glc residue to produce trisaccharide 6. Two thio analogs (7, 8) of trisaccharide 6, where the oxygen atoms in the glycosidic linkages between sugar residues were replaced by sulfur, were prepared by multistep chemical synthesis that made use of the key intermediates 1,2-anhydro-3,4,6-tri-O-benzyl-α-D-glucose (10) and 1,2-anhydro-3,4,6-tri-O-benzyl-β-D-mannose (13) as donors for the glycosylations. The thio analogs (7,8) were kinetically evaluated as substrates for GlcNAcT-V and found to be acceptors with two- to three-fold increase in Vmax but higher Km values (7, Km = 376 μM; 8, Km = 300 μM) than their parent compound 6 (Km = 111 μM), which has the natural oxygen linkage. The thio analogs 7 and 8 could be quantitatively converted into the expected product tetrasaccharides (27, 28) by incubation with GlcNAcT-V and UDP-GlcNAc. The enzymatic results indicate that GlcNAcT-V tolerates the substitution of the natural oxygen linkage of the acceptor by a sulfur linkage. Keywords: N-acetylglucosaminyltransferase-V, enzyme acceptors, trisaccharide analogs, thioglycosides.
