• Development of Stable Phosphohistidine Analogues

  and Tyr residues, our understanding of histidine phosphorylation is relatively limited, particularly in higher eukaryotes, due to technical difficulties stemming from the intrinsic instability and isomerism of phosphohistidine (pHis). We report the design and synthesis of stable and nonisomerizable pHis analogues. These pHis analogues were successfully utilized in solid-phase peptide synthesis and semi-synthesis

  蛋白质磷酸化是最常见和最广泛研究的翻译后修饰 (PTM) 之一。与 Ser、Thr 和 Tyr 残基的 O 磷酸化相比，我们对组氨酸磷酸化的理解相对有限，尤其是在高等真核生物中，由于磷酸组氨酸 (pHis) 的内在不稳定性和异构现象所带来的技术困难。我们报告了稳定和非异构化 pHis 类似物的设计和合成。这些 pHis 类似物已成功用于固相肽合成和组蛋白 H4 的半合成。值得注意的是，使用合成肽作为免疫原获得了特异性识别pHis的第一抗体。

  New [(18) F]fluorinated 1,2,3-triazolyl amino acid derivatives were efficiently prepared from Huisgen 1,3-dipolar cycloaddition reactions, well known as click reaction. We developed two simultaneous click reactions in one-pot with a simple solid-phase extraction (SPE) purification method. [(18) F]fluoro-1-propyne was obtained at a 45% non-decay corrected radiochemical yield based on the [(18) F]fluoride

  新的 [(18) F] 氟化 1,2,3-三唑基氨基酸衍生物是从 Huisgen 1,3-偶极环加成反应（众所周知的点击反应）有效制备的。我们使用简单的固相萃取 (SPE) 纯化方法在一锅中开发了两个同步点击反应。[(18) F] 氟-1-丙炔基于 [(18) F] 氟离子以 45% 的非衰变校正放射化学产率获得。使用未保护的叠氮烷基氨基酸 [(18) F] 氟-1-丙炔和亲脂性添加剂炔进行一锅式和同时两次点击反应，以产生三种合成氨基酸衍生物 AMC-101 ([(18 ) F]-6a)、AMC-102 ([(18) F]-6b) 和 AMC-103 ([(18) F]-6c) 具有 29%、28% 和 24% 的非衰减校正分别为放射化学产率。所有放射性示踪剂均表明放射化学纯度 > 95% 无任何残留有机溶剂。我们的新方法涉及一锅中的两次点击反应，通过从同时进行的两次点击反应中轻松去除残留的前体，显示出高放射化学和化学纯度。

  Crosslinking amino acids are naturally existing protein crosslinkers. Herein, we described the synthesis of several novel bis-amino acids constituted of serine, alanine, lysine, and tyrosine with click chemistry. The Huisgen 1,3-dipolar cycloadditions between azido- and alkyne-functionalized amino acids can be easily realized in the presence of catalytic amount of CuSO4 and Na ascorbate. In addition

  交联氨基酸是天然存在的蛋白质交联剂。在这里，我们用点击化学描述了由丝氨酸，丙氨酸，赖氨酸和酪氨酸组成的几种新型双氨基酸的合成。在催化量的CuSO 4和抗坏血酸钠存在下，叠氮基和炔基官能化氨基酸之间的Huisgen 1,3-偶极环加成反应很容易实现。另外，还使用蒽，荧光素和苯并噻二唑作为荧光团制备了荧光双氨基酸衍生物。用对称的双炔苯并噻二唑，可以合成带有两个不同氨基酸部分的不对称衍生物。
• A Fluorogenic Probe for the Catalyst-Free Detection of Azide-Tagged Molecules

  Fluorogenic reactions in which non- or weakly fluorescent reagents produce highly fluorescent products can be exploited to detect a broad range of compounds including biomolecules and materials. We describe a modified dibenzocyclooctine that under catalyst-free conditions undergoes fast strain promoted cycloadditions with azides to yield strongly fluorescent triazoles. The Cycloaddition products are more than 1000-fold brighter compared to the Starting cyclooctyne, exhibit large Stokes shift,. and can be excited above 350 nm, which is required for many applications. Quantum mechanical: calculations indicate that the fluorescence increase upon triazole formation is due to large differences in oscillator strengths of the S-0 <-> S-1 transitions in the planar C-2v-symmetric starting material compared to the symmetry broken and nonplanar.cycloaddition products. The new fluorogenic probe was successfully employed for labeling of proteins modified by an azide moiety.
• Stable triazolylphosphonate analogues of phosphohistidine

  Histidine-phosphorylated proteins and the corresponding kinases are important components of bacterial and eukaryotic cell-signalling pathways, and are therefore potential drug targets. The study of these biomolecules has been hampered by the lability of the phosphoramidate functional group in the phosphohistidines and the lack of generic antibodies. Herein, the design and concise synthesis of stable triazolylphosphonate analogues of N1- and N3-phosphohistidine, and derivatives suitable for bioconjugation, are described.
