    strain energy, reactions of thiols with cyclopropenyl ketones are both fast and irreversible and give rise to stable conjugate addition adducts. The resulting cyclopropenyl ketones have a low molecular weight and allow for simple attachment of amides via N-hydroxysuccinimide (NHS)-esters. While cyclopropenyl ketones do display slow background reactivity toward water, labeling by thiols is much more rapid
    描述了使用环丙烯基酮进行半胱酸烷基化的方法。由于环丙烯应变能的显着释放,醇与环丙烯基酮的反应既快速又不可逆,并产生稳定的共轭加合物。所得的环丙烯基酮具有低分子量,并允许经由N-羟基琥珀酰亚胺(NHS)-酯简单地连接酰胺。虽然环丙烯基酮确实对显示出较慢的背景反应性,但醇标记的速度要快得多。环丙烯基酮与谷胱甘肽(GSH)的反应以595 M -1 s -1的速率进行在pH 7.4的PBS中比α-卤代羰基标记试剂要快得多,并且与马来酰亚胺/偶联剂竞争。该方法已在蛋白质偶联中得到证明,并且在GSH或人血浆中长时间孵育后,芳基硫醇盐偶联物被证明是稳定的。最后,使用环丙烯基酮来生成基于PEG凝胶,该凝胶对在还原环境中的长时间孵育稳定。
  • Tuning the Hydrolytic Stability of Next Generation Maleimide Cross-Linkers Enables Access to Albumin-Antibody Fragment Conjugates and tri-scFvs

    日期:2018.2.21
    We describe investigations to expand the scope of next generation maleimide cross-linkers for the construction of homogeneous protein–protein conjugates. Diiodomaleimides are shown to offer the ideal properties of rapid bioconjugation with reduced hydrolysis, allowing the cross-linking of even sterically hindered systems. The optimized linkers are exploited to link human serum albumin to antibody fragments (Fab or scFv) as a prospective half-life extension platform, with retention of antigen binding and robust serum stability. Finally, a triprotein conjugate is formed, by linking scFv antibody fragments targeting carcinoembryonic antigen. This tri-scFv is shown to infer a combination of greater antigen avidity and increased in vivo half-life, representing a promising platform for antibody therapeutic development.
    我们描述了扩大下一代马来酰亚胺交联剂的范围以构建均质蛋白质-蛋白质缀合物的研究。二马来酰亚胺被证明具有快速生物共轭的理想特性,同时减少了解,甚至可以实现空间位阻系统的交联。优化的接头用于将人血清白蛋白连接到抗体片段(Fab 或 scFv),作为预期的半衰期延长平台,同时保留抗原结合和强大的血清稳定性。最后,通过连接靶向癌胚抗原的 scFv 抗体片段,形成三蛋白缀合物。这种三链抗体被证明具有更高的抗原亲合力和更长的体内半衰期,代表了抗体治疗开发的一个有前途的平台。

    The performance of cationic liposomes for delivery of therapeutic nucleic acids in vivo can be improved and specifically tailored to certain types of cargo and target cells by incorporation of PEG-containing lipoconjugates in the cationic liposome’s composition. Here, we report on the synthesis of novel PEG-containing lipoconjugates with molecular masses of PEG 800, 1500 and 2000 Da. PEG-containing lipoconjugates were used as one of the components in liposome preparation with the polycationic amphiphile 1,26-bis(cholest-5-en-3β-yloxycarbonylamino)-7,11,16,20-tetra-azahexacosan tetrahydrochloride (2X3) and the lipid-helper dioleoylphosphatidylethanolamine (DOPE). We demonstrate that increasing the length of the PEG chain reduces the transfection activity of liposomes in vitro, but improves the biodistribution, increases the circulation time in the bloodstream and enhances the interferon-inducing activity of immunostimulating RNA in vivo.

    阳离子脂质体在体内传递治疗核酸的表现可以通过将含PEG的脂质共轭物纳入阳离子脂质体的组成中进行改进和特定定制以适应某些类型的载荷和目标细胞。在这里,我们报告了PEG含量为800、1500和2000 Da的新型PEG含量的脂质共轭物的合成。PEG含量的脂质共轭物被用作脂质体制备中的一个组分,与多阳离子两亲分子1,26-双(胆固醇-5-烯-3β-氧羰基基)-7,11,16,20-四氮杂六十烷四盐酸盐(2X3)和脂质助剂二油基磷脂酰乙醇胺(DOPE)一起使用。我们证明,增加PEG链的长度会降低体外脂质体的转染活性,但会改善生物分布,增加在血液循环中的时间,并增强体内免疫刺激RNA的干扰素诱导活性。
