    摘要:
    抗体的位点特异性标记和偶联对于基础研究和开发更有效的诊断和治疗方法是非常需要的。我们在这里报告了一种通用且稳健的化学酶法,该方法允许对抗体进行一锅式位点特异性功能化。设计、合成和评估了一系列选择性修饰的二糖恶唑啉衍生物,作为抗体 Fc 聚糖重塑的不同内切糖苷酶的供体底物。我们发现,在测试的几种内切糖苷酶中,来自化脓性链球菌的野生型内切糖苷酶血清型 M49 (Endo-S2) 在将带有位点选择性修饰的叠氮化物、生物素或荧光标签的功能化二糖转移到抗体而不水解产生的转糖基产物方面表现出显着的活性。这一发现连同 Endo-S2 对重组抗体的出色 Fc 去糖基化活性,允许以一锅法直接标记和功能化抗体,无需中间体和酶分离。位点特异性引入不同数量的叠氮基团使得能够高效合成均相抗体-药物偶联物 (ADC),并通过无铜方法精确控制药物抗体比 (DAR) 在 2 到 12 之间应变促进的点击反应。细胞活力测定表明,与具有较低

    用 6-磷酸甘露糖 (M6P) 聚糖配体对治疗性溶酶体酶进行功能化是增强阳离子非依赖性 M6P 受体 (CI-MPR) 介导的细胞摄取的主要策略,从而提高酶的整体治疗功效。然而,最小的高亲和力 M6P 含N-聚糖配体仍有待鉴定,它们与治疗性溶酶体酶的有效和位点选择性缀合是一项具有挑战性的任务。我们在此报告截短的 M6P-聚糖恶唑啉的化学合成及其在重组人酸性 α-葡萄糖苷酶 (rhGAA) 的酶促聚糖重塑中的应用,该酶用于治疗庞贝病,这是一种由糖原缺乏引起的疾病-降解溶酶体酶。构效关系研究确定 M6P 四糖恶唑啉是酶促转糖基化的最小底物,可产生 CI-MPR 的高亲和力 M6P 聚糖配体。利用内切糖苷酶 Endo-A 和 Endo-F3 的底物特异性,我们发现 Endo-A 和 Endo-F3 可以有效地去糖基化各自的高甘露糖和复合型rhGAA 中的N-聚糖和位点选择性地将合成的 M6P N-聚糖转移到去糖基化的

    Mannose-6-phosphate (M6P)-terminated oligosaccharides are important signals for M6P-receptor-mediated targeting of newly synthesized hydrolases from Golgi to lysosomes, but the precise structural requirement for the M6P ligand-receptor recognition has not been fully understood due to the difficulties in obtaining homogeneous M6P-containing glycoproteins. We describe here a chemoenzymatic synthesis of homogeneous
    6-磷酸甘露糖 (M6P) 末端寡糖是 M6P 受体介导的将新合成的解酶从高尔基体靶向溶酶体的重要信号,但由于 M6P 配体受体识别的精确结构要求尚未完全了解难以获得均质的含 M6P 的糖蛋白。我们在这里描述了携带天然 M6P 的 N-聚糖的均质磷酸糖蛋白的化学酶促合成。该方法包括化学合成具有不同数量和位置的 M6P 部分的聚糖恶唑啉,并通过内切糖合酶将它们转移到 GlcNAc 蛋白,以提供均质的含 M6P 的糖蛋白。还完成了两个 M6P-寡糖与环状多肽的同时连接以产生二价 M6P-糖肽。表面等离子体共振结合研究表明,位于低聚甘露糖环境的低 α-1,3-分支的单个 M6P 部分足以与受体 CI-MPR 高亲和力结合,而在 α 处存在 M6P 部分-1,6-分支是可有可无的。此外,对二价环状和线性多肽的结合研究表明,两个 M6P-寡糖配体的紧密接近对于实现对 CI-MPR 受体的高亲和力至关重要。总之,本研究表明
  • Convergent Synthesis of Homogeneous Glc<sub>1</sub>Man<sub>9</sub>GlcNAc<sub>2</sub>-Protein and Derivatives as Ligands of Molecular Chaperones in Protein Quality Control
    作者:Mohammed N. Amin、Wei Huang、Rahman M. Mizanur、Lai-Xi Wang

    日期:2011.9.14
    A detailed understanding of the molecular mechanism of chaperone-assisted protein quality control is often hampered by the lack of well-defined homogeneous glycoprotein probes. We describe here a highly convergent chemoenzymatic synthesis of the monoglucosylated glycoforms of bovine ribonuclease (RNase) as specific ligands of lectin-like chaperones calnexin (CNX) and calreticulin (CRT) that are known to recognize the monoglucosylated high-mannose oligosaccharide component of glycoproteins in protein folding. The synthesis of a selectively modified glycoform Gal(1)Glc(1)Man(9)GlcNAc(2)-RNase was accomplished by chemical synthesis of a large N-glycan oxazoline and its subsequent enzymatic ligation to GlcNAc-RNase under the catalysis of a glycosynthase. Selective removal of the terminal galactose by a beta-galactosidase gave the Glc(1)Man(9)GlcNAc(2)-RNase glycoform in excellent yield. CD spectroscopic analysis and RNA-hydrolyzing assay indicated that the synthetic RNase glycoforms maintained essentially the same global conformations and were fully active as the natural bovine ribonudease B. SPR binding studies revealed that the Glc(1)Man(9)GlcNAc(2)-RNase had high affinity to lectin CRT, while the synthetic Man(9)GlcNAc(2)-RNase glycoform and natural RNase B did not show CRT-binding activity. These results confirmed the essential role of the glucose moiety in the chaperone molecular recognition. Interestingly, the galactose-masked glycoform Gal(1)Glc(1)Man(9)GlcNAc(2)-RNase also showed significant affinity to lectin CRT, suggesting that a galactose beta-1,4-linked to the key glucose moiety does not significantly block the lectin binding. These synthetic homogeneous glycoprotein probes should be valuable for a detailed mechanistic study on how molecular chaperones work in concert to distinguish between misfolded and folded glycoproteins in the protein quality control cycle.

    The present disclosure provides compounds useful for enzymatic glycan remodeling of a glycoprotein. Also provided is a method for remodeling a glycoprotein using M6P-glycan oxazolines in a one-pot deglycosylation/transglycosylation process, which may enable siteselective M6P-glycan remodeling of glycoproteins to obtain homogeneous products. The remodeled glycoprotein (such as a recombinant human acid α-glucosidase) may have enhanced affinity for the CI-MPR, increased uptake by a cell, and improved therapeutic efficacy compared to the original glycoprotein. A method of treating Pompe disease using a glycanremodeled lysosomal enzyme is also provided.
