  • Synthetic Studies on Glycopeptides Concerned with Defense Response of Plants. I. Syntheses of Supprescins A and B.
    作者:Takuya KANEMITSU、Yukio OGIHARA、Tadahiro TAKEDA
    DOI:10.1248/cpb.45.643
    日期:——
    Two glycopeptides, supprescins A and B, that suppress the production of pisatin, a phytoalexin of pea, were synthesized. In the synthesis of supprescin A, condensation of 3, 4, 6-tri-O-acetyl-2-azido-2-deoxy-α-D-galactopyranosyl trichloroacetimidate or its glycosidic β isomer with N-(carbobenzoxy)-L-seryl-O-benzyl-L-seryl-glycine methyl ester was carried out in the presence of trimethylsilyl trifluoromethanesulfonate (TMSOTf) to give the monoglycosyl tripeptide derivatives. For the synthesis of supprescin B, glycosylation of 2, 3, 4, 6-tetra-O-acetyl-α-D-galactopyranosyl bromide and 1, 2, 3, 6-tetra-O-benzoyl-α-D-galactopyranose was promoted by silver trifluoromethanesulfonate (AgOTf) to provide a disaccharide derivative. The coupling of diglycosyl imidate, 2, 3, 4, 6-tetra-O-acetyl-β-D-galactopyranosyl-(1→4)-3, 6-di-O-benzoyl-2-azido-2-deoxy-D-galactopyranosyl trichloroacetimidate, and N-(carbobenzoxy)-L-seryl-O-benzyl-L-seryl-glycyl-4-benzyl-L-aspartyl-5-benzyl-L-glutamyl-O-benzyl-L-threonine methyl ester in the presence of TMSOTf afforded the diglycosyl hexapeptide derivatives. Reduction, followed by N-acetylation, and then removal of the remaining protecting groups afforded the desired supprescin B.
    两种糖肽,抑制蛋白A和B,能够抑制豌豆中一种植物抗毒素——豌豆素的合成,它们已被制备出来。在制备抑制蛋白A的过程中,三甲基三氟甲磺酸酯(TMSOTf)的存在下,将3,4,6-三-O-乙酰基-2-叠氮-2-脱氧-α-D-半乳糖喃糖基三酰亚胺酯或其糖苷β异构体与N-(羧基苄氧羰基)-L-丝氨酸-O-苄基-L-丝酰甘酸甲酯进行缩合反应,得到单糖基三肽衍生物。在制备抑制蛋白B的过程中,2,3,4,6-四-O-乙酰基-α-D-半乳糖喃糖基和1,2,3,6-四-O-苯甲酰基-α-D-半乳糖喃糖在三氟甲磺酸(AgOTf)的促进下进行糖基化反应,生成二糖衍生物。在TMSOTf的存在下,将二糖基亚胺酯,2,3,4,6-四-O-乙酰基-β-D-半乳糖喃糖基-(1→4)-3,6-二-O-苯甲酰基-2-叠氮-2-脱氧-D-半乳糖喃糖基三酰亚胺酯与N-(羧基苄氧羰基)-L-丝氨酸-O-苄基-L-丝酰甘酰-4-苄基-L-天冬酰-5-苄基-L-谷酰-O-苄基-L-苏氨酸甲酯进行偶联反应,得到二糖基六肽衍生物。随后进行还原、N-乙酰化和剩余保护基团的去除,最终得到了所需的抑制蛋白B。

    Fuc-Gal-anhydroGlcNAc with single free 3'-OH group. Its standard α-galactosylation gave protected B (type 2) tetrasaccharide. For synthesis of correspondent A tetrasaccharide seven different 2-azido-2-deoxygalactosyl (GalN3) donors were tested: 6-O-acetyl-3,4-O-isopropylidene-GalN3 thioglycoside was shown to provide the best yield (89%) and stereoselectivity (α/β = 24:1). Further 1,6-anhydro cycle opening

    DOI:10.1071/ch09058
    日期:——
    H type V and VI antigens in multi-milligramme quantities as part of an overall goal to prepare all 18 A, B, and H antigens. The A and B type V and VI antigens were prepared with a 7-octen-1-yl linker, to enable future conjugation to a protein or solid support. The H type V and VI antigens were prepared as the octyl glycoside, to facilitate detailed enzyme kinetics studies.
    长期以来,化学家,生物化学家和进化生物学家都对ABO组织血型抗原感兴趣。然而,迄今为止,尽管该小组有可能提供对这些聚糖基序的生物学作用的更详细的了解,但尚未进行所有ABO组织血型组抗原的完整合成。在这里,我们报告以毫克级的数量对A,B和H型V和VI抗原进行化学合成,这是制备所有18种A,B和H抗原的总体目标的一部分。使用7-辛烯-1-基接头制备A型和B型V型和VI型抗原,以便将来与蛋白质或固体支持物结合。H型V和VI型抗原被制备为辛基糖苷,以促进详细的酶动力学研究。
