  Synthetic Mimics of Small Mammalian Cell Surface Receptors

  摘要：

  Receptors on the surface of mammalian cells promote the uptake of cell-impermeable ligands by receptor-mediated endocytosis. To mimic this process, we synthesized small molecules designed to project anti-dinitrophenyl antibody-binding motifs from the surface of living Jurkat lymphocytes. These synthetic receptors comprise N-alkyl derivatives of 3beta-cholesterylamine as the plasma membrane anchor linked to 2,4-dinitrophenyl (DNP) and structurally similar fluorescent 7-nitrobenz-2-oxa-1,3-diazole (NBD) headgroups. Insertion of two beta-alanine subunits between a DNP derivative and 3beta-cholesterylamine yielded a receptor that avidly associates with cell surfaces (cellular t(1/2) similar to 20 h). When added to Jurkat cells at 10 muM, this receptor enhanced uptake of an anti-DNP IgG ligand by similar to200-fold in magnitude and similar to400-fold in rate within 4 h (ligand internalization t(1/2) similar to 95 min at 37 degreesC). This non-natural receptor mimics many natural receptors by dynamically cycling between plasma membranes and intracellular endosomes (recycling t(1/2) similar to 3 min), targeting of protein ligands to proposed cholesterol and sphingolipid-enriched lipid raft membrane microdomains, and delivery of protein ligands to late endosomes/lysosomes. Quantitative dithionite quenching of fluorescent extracellular NBD headgroups demonstrated that other 3beta-cholesterylamine derivatives bearing fewer beta-alanines in the linker region or N-acyl derivatives of 3beta-cholesterylamine were less effective receptors due to more extensive trafficking to internal membranes. Synthetic cell surface receptors have potential applications as cellular probes, tools for drug delivery, and methods to deplete therapeutically important extracellular ligands.

  摘要：

  Cu（I）催化炔叠氮化物[2 + 3]环加成反应是将生物分子共价固定在磁性纳米颗粒（MNP）上的有效且正交的共轭反应。MNP表面上的叠氮基可提供更好的与烷基化分子的结合效率。此外，将C末端链化的蛋白位点特异性地固定在MNP上。通过位点特异性固定表现出的蛋白质结合活性高于通过随机酰胺键形成所表现出的蛋白质结合活性。

  日期：2007.10.1

  Ultraviolet photodissociation (UVPD) of chromophore-modified peptides enhances the capabilities for de novo sequencing in a quadrupole ion trap mass spectrometer. Attachment of UV chromophores allows efficient photoactivation of not only the precursor ions but also any fragments that retain the chromophore functionality. For doubly protonated peptides, UVPD leads to a vast reduction in MS/MS complexity

  发色团修饰的肽的紫外光解离（UVPD）增强了四极离子阱质谱仪中从头测序的能力。紫外线发色团的附着不仅可以有效地激活前体离子，而且还可以保留任何保留发色团功能的碎片。对于双质子化肽，UVPD导致MS / MS复杂性大大降低。根据生色团的位置（即N端或C端），通过UVPD将碰撞激活解离时通常看到的b和y离子阵列还原为y或b离子的单个序列。磺化试剂Alexa Fluor 350（AF350）通过UVPD为单电荷和双电荷肽提供了最佳的总体结果。AF350的非磺化类似物7-氨基-4-甲基香豆素-3-乙酸 还通过UVPD简化了带双电荷但不带单电荷的肽的光谱。二硝基苯基肽还可以通过UVPD产生简化的光谱，尽管伴随一系列诊断性y离子有少量内部碎片。此MS / MS简化过程的成功源自暴露于后续激光脉冲时任何含发色团的片段的广泛二次断裂。能量可变的UVPD显示，不含生色团的y碎片离子的丰度随激光脉冲能量线性增
