• Novel template-assembled oligosaccharide clusters as epitope mimics for HIV-neutralizing antibody 2G12. Design, synthesis, and antibody binding study

  The synthesis of a new class of template-assembled oligomannose clusters as the mimics of the epitope of the HIV-neutralizing antibody 2G12 is described. The novel oligomannose clusters were successfully assembled on a cyclic decapeptide template using the Cu(I)-catalyzed 1,3-dipolar cycloaddition of azides to alkynes by introducing four units of a synthetic D1 arm tetrasaccharide (Manα1,2Manα1,2Manα1,3Manα-) of high-mannose N-glycan on one face of the template and two T-helper epitope peptides on the other face of the template. Their binding to human antibody 2G12 was studied using surface plasmon resonance (SPR) technology. It was found that while the synthetic monomeric D1 arm oligosaccharide and its fluorinated derivative interacted with 2G12 only weakly, the corresponding template-assembled oligosaccharide clusters showed high affinity to antibody 2G12, indicating a clear clustering effect in 2G12 recognition. Interestingly, the fluorinated D1 arm cluster, in which the 6-OH of the terminal mannosyl residue was replaced with a fluorine atom, showed a distinct kinetic model in 2G12 binding as compared with the cluster of the natural D1 arm oligosaccharides. The oligosaccharide clusters with varied length of spacer demonstrated different affinity to 2G12, suggesting that an appropriate spatial orientation of the sugar chains in the cluster was crucial for high affinity binding to the antibody 2G12. It was also found that the introduction of two T-helper epitopes onto the template did not affect the structural integrity of the oligomannose cluster. The novel synthetic glycoconjugates represent a new type of immunogen that may be able to raise carbohydrate-specific neutralizing antibodies against HIV-1.

  描述了一种新型模板组装的寡甘露聚糖簇的合成，该簇模仿了HIV中和抗体2G12的表位。这些新颖的寡甘露聚糖簇成功地在一个环状十肽模板上组装，采用了铜(I)催化的叠氮化物与炔烃的1,3-极性环加成反应，通过在模板的一侧引入四个单位的合成D1臂四糖（Manα1,2Manα1,2Manα1,3Manα-）和在另一侧引入两个T辅助表位肽。使用表面等离子共振（SPR）技术研究了它们与人抗体2G12的结合。研究发现，虽然合成的单体D1臂寡糖及其氟化衍生物与2G12的相互作用非常弱，但相应的模板组装的寡糖簇对抗体2G12显示出高亲和力，表明在2G12识别中存在明显的聚集效应。有趣的是，氟化D1臂簇中末端甘露糖残基的6-OH被氟原子取代时，与天然D1臂寡糖簇相比，其在与2G12结合时展现出明显不同的动力学模型。具有不同长度间隔链的寡糖簇对2G12的亲和力表现出不同，表明聚糖链在簇中的适当空间取向对于与抗体2G12的高亲和力结合至关重要。研究还发现，在模板上引入两个T辅助表位并没有影响寡甘露聚糖簇的结构完整性。这些新颖的合成糖 conjugates 代表了一种新型免疫原，可能能够引发针对HIV-1的特异性中和抗体。

  Two oligosaccharides, alpha-D-Manp-(1 --> 2)-alpha-D-Manp-(1 --> 2)-alpha-D-Manp-(1 --> 6)-alpha-D-Manp-(l --> 4)-alpha-D-GlcpNAc (I) and alpha-D-Manp-(1 --> 3)-alpha-D-Manp-(1 --> 2)-alpha-D-Manp-(1 --> 2)-alpha-D-Manp-(1 --> 6)-alpha-D-Manp-(1 --> 4)-alpha-D-GlcpNAc (II), the glycosylphosphatidylinositol (GPI) anchor glycans from S. cerevesiae and A. fumigatus were synthesized as their methyl glycosides in a regio- and stereoselective manner. The pentasaccharide I was obtained from 6-O-selective glycosylation of methyl 2,3-di-O-benzoyl-alpha-D-mannopyranosyl-(l --> 4)-2-acetamido-3,6-di-O-benzoyl-2-deoxy-alpha-D-glucopyranoside (8) with 2-O-acetyl-3,4,6-tri-O-benzoyl-alpha-D-mannopyranosyl-(1 --> 2) -3,4,6-tri-O-benzoyl-alpha-D-mannopyranosyl trichloroacetimidate (9), followed by benzoylation, deacetylation, and mannosylation, and then by deprotection. The hexasaccharide (II) was obtained via condensation of allyl 3,4,6-tri-O-benzoyl-alpha-D-mannopyranosyl-(l --> 2)-3,4,6-tri-O-benzoyl-alpha-D-mannopyranoside (17) with 2,3,4,6-tetra-O-benzoyl-alpha-D-mannopyranosyl-(1 --> 3)-2,4,6-tri-O-acetyl-alpha-D-mannopyranosyl trichloroacetimidate (16), followed by deallylation, trichloroacetimidation, and coupling with acceptor (8), and finally by deprotection.
