  Oligo-Asp Tag/Zn(II) 复合探针作为蛋白质标记和荧光成像的新对

  摘要：

  为了在复杂的生物系统中完成对特定蛋白质的选择性标记，需要掺入蛋白质中的肽标签和互补的小分子探针。尽管已经开发了多种肽标签/探针对作为蛋白质分析的分子工具，但适用于蛋白质实时成像的对的可用性仍然有限。我们现在报告了一个新的肽标签/人工探针对，由可遗传编码的低聚天冬氨酸序列（D4 标签，(D4)n，n = 1-3）和相应的多核 Zn(II) 复合物 (Zn(II)- DpaTyrs）。Zn(II)-DpaTyr 探针与 D4 标签的强结合亲和力是多重配位键和多价效应的结果。用等温滴定量热法定量测定。

  Conformationally flexible platelet aggregation inhibitors based on the tetrapeptide Arg-Gly-Asp-Arg

  摘要：

  A series of nonpeptide fibrinogen receptor antagonists based upon the tetrapeptide Arg-Gly-Asp-Arg were prepared. These relatively simple derivatives incorporate a high degree of conformational flexibility that was anticipated to allow them to attain the requisite conformation for binding to the platelet fibrinogen receptor. Optimization of the distances between the required acidic and basic functional groups led eventually to compound 7, which is a one hundred-fold more potent inhibitor of platelet aggregation than the peptide it is based upon.

  A complementary recognition pair consisting of a genetically encodable peptide tag and a small molecular probe is a powerful tool to specifically label and manipulate a protein of interest under biological conditions. In this study, we report the redesign of a tag–probe pair comprising an oligo-aspartate peptide tag (such as DDDD) and a binuclear zinc complex. Isothermal-titration calorimetry screening of binding between the series of peptides and zinc complexes revealed that the binding affinity was largely influenced by subtle changes of the ligand structure of the probe. However, the binding was tolerant to differences of the tag peptide sequence. Of those tested, a pair containing a peptide tag (DDAADD) and a binuclear zinc complex possessing 4-chloropyridines (3-2Zn(II)) showed the strongest binding affinity (Ka = 3.88 × 105 M−1), which was about 10-fold larger than the conventional pair of D4-peptide tag (DDDD) and 1-2Zn(II) containing nonsubstituted pyridines (Ka = 3.73 × 104 M−1). The strong binding of this new complementary recognition pair enabled the rapid covalent labeling of a tag-fused maltose binding protein with a fluorescent zinc complex, demonstrating its potential utility in protein analysis.

  一种由遗传编码可表达的多肽标签和小分子探针组成的互补识别对，是在生物条件下特异性地标记和操控感兴趣蛋白的有力工具。本研究中，我们报道了一种标签-探针对的设计重构，该对由寡天冬氨酸多肽标签（如DDDD）和双核锌复合物组成。等温滴定量热法筛选一系列多肽与锌复合物之间的结合发现，结合亲和力主要受探针配体结构的细微变化影响。然而，结合对标签多肽序列的差异具有容忍性。在测试的组合中，包含多肽标签（DDAADD）和含4-氯吡啶的双核锌复合物（3-2Zn(II)）的组合显示出最强的结合亲和力（Ka = 3.88 × 105 M−1），比传统的D4多肽标签（DDDD）与不含取代吡啶的1-2Zn(II)组合的亲和力大约强10倍（Ka = 3.73 × 104 M−1）。这种新的互补识别对强大的结合力使得能够快速共价标记融合了标签的麦芽糖结合蛋白与荧光锌复合物，展示了其在蛋白质分析中的潜在应用价值。

  of a short‐peptide tag and a small molecular probe is a versatile molecular tool for protein detection, handling, and purification, and so forth. In this manuscript, we report that the binuclear NiII‐DpaTyr (DpaTyr=bis((dipicolylamino)methyl)tyrosine) complex serves as a strong binding probe for an oligo‐aspartate tag tethered to a protein. Among various binuclear metal complexes of M‐DpaTyr (M=ZnII

  短肽标签和小分子探针的互补识别对是用于蛋白质检测，处理和纯化等的多功能分子工具。在此手稿中，我们报道了双核Ni II -DpaTyr（DpaTyr =双（（二吡啶甲酰基氨基）甲基）酪氨酸）复合物可作为与蛋白质连接的低聚天冬氨酸标签的强结合探针。在M‐DpaTyr的各种双核金属络​​合物中（M = Zn II，Ni II，Mn II，Cu II，Cd II，Co III和Fe III），我们发现Ni II‐ DpaTyr（1-2 Ni2 +）显示出强结合亲和力（表观结合常数：ķ应用≈10 5 中号-1），用于寡聚天门冬氨酸的肽中性含水条件下（50米中号HEPES，百米中号NaCl，pH为7.2）。等温滴定热量法（ITC）的详细研究表明，三天冬氨酸D3标签（DDD）是1-2Ni2 +在1：1结合化学计量法中识别的最佳序列。另一方面，除Ni II-和Zn II -DpaTyr外，DpaTyr的其

  This Letter describes the continued SAR exploration of small molecule Legumain inhibitors with the aim of developing a potent and selective in vitro tool compound. Work continued in this Letter explores the use of alternative P2-P3 linker units and the P3 group SAR which led to the identification of 10t, a potent, selective and cellularly active Legumain inhibitor. We also demonstrate that 10t has activity in both cancer cell viability and colony formation assays. (C) 2015 Elsevier Ltd. All rights reserved.
