    GLYCOSYNTHASE VARIANTS FOR ANTIBODY-DRUG CONJUGATE ENGINEERING
    摘要:
    The present disclosure relates to novel glycosynthase enzymes for antibody-drug conjugates (ADCs) engineering. The enzyme variants, termed EndoSd-D232M and EndoSz-D234M, contain the glycan conjugation and/or modification activity at the conserved N297 glycosylation site of Fc region of an exemplary antibody. It has been demonstrated that the glycosynthase activities of EndoSd-D232M and EndoSz-D234M can be applied to various mAbs targeting different receptors, including, but not limited to, Globo H, SSEA-4, SSEA-3 series of receptors (OBI-888; Globo H ganglioside), Herceptin (Her 2 receptor), Peijeta (Her 2 receptor) and Vectibix (EGFR receptor). It has been found that both mAb-GlcNAc and mAb- GlucNAc(F) were suitable substrates for both EndoSd-D232M and EndoSz-D234M.

  • Applications of Shoda's reagent (DMC) and analogues for activation of the anomeric centre of unprotected carbohydrates
    作者:Antony J. Fairbanks
    DOI:10.1016/j.carres.2020.108197
    日期:2021.1
    its derivatives are useful for numerous synthetic transformations in which the anomeric centre of unprotected reducing sugars is selectively activated in aqueous solution. As such unprotected sugars can undergo anomeric substitution with a range of added nucleophiles, providing highly efficient routes to a range of glycosides and glycoconjugates without the need for traditional protecting group manipulations
    2-氯-1,3-二甲基咪唑啉氯化物(DMC,本文也称为 Shoda 试剂)及其衍生物可用于许多合成转化,其中未保护的还原糖的异头中心在水溶液中被选择性激活。由于此类未受保护的糖可以用一系列添加的亲核试剂进行异头取代,从而为一系列糖苷和糖缀合物提供高效途径,而无需进行传统的保护基操作。这篇简短的评论总结了 DMC 及其一些衍生物/类似物的发展,并重点介绍了保护无基团合成的最新应用。

    facile and practical method for synthesis of sugar oxazolines (=dihydrooxazoles) from the corresponding Nacetyl2‐amino sugars has been developed by using 2‐chloro‐1,3‐dimethyl‐1H‐benzimidazol‐3‐ium chloride (CDMBI) as a dehydrative condensing agent. The intramolecular dehydrative reaction between the 2‐acetamido group and the anomeric OH group of unprotected Nacetyl2‐amino sugars took place smoothly

    Glycosynthases are promising enzyme catalysts for glycoside synthesis. Derived from glycoside hydrolases by mechanistic repurposing of their active site, glycosynthases utilize suitably activated glycosyl donors for glycosylation, yet they are unable to hydrolyze the products thus formed. Although primed for synthetic application by their design, glycosynthases have yet to see actual use in carbohydrate
    糖苷合酶是用于糖苷合成的有前途的酶催化剂。糖基合酶通过机械地改变其活性位点而衍生自糖苷水解酶,其利用适当活化的糖基供体进行糖基化,但是它们不能水解由此形成的产物。尽管通过其设计为合成应用做好了准备,但糖合酶尚未见到在碳水化合物生产中的实际用途。为了挑战从过程化学观点出发对糖合酶适用性的限制,我们在此开发了一种双歧双歧杆菌β- N-乙酰基己糖胺酶的糖合酶(D746E变体),该酶具有很高的合成活性(≥100μmolmin –1 mg –1)。使用时具有化学和区域选择性Ñ乙酰基d -葡糖胺1,2-恶唑啉为乳糖β-1,3-糖基化。因此,我们建立了一种化学酶法工艺技术,用于生产人乳寡糖的核心结构单位乳糖-N-三糖II。使用恶唑啉的等量(化学制备,40%收率从Ñ乙酰基d -葡糖胺)和乳糖,我们获得了lacto- Ñ -triose II(515毫米; 281毫克毫升-1 ;约90%产率;≤1ħ反应时间
