  Cross‐metathesis ofC‐Glycosides and Peptides

  摘要：

  Peptides bearing an acryloyl residue at their N-terminus were coupled with various C-glycosides in an equimolar ratio via cross-metathesis. The newly formed olefin was obtained with high E/Z selectivity in satisfying to high yields with low homodimerization of the starting materials. The posttranslational cross-metathesis approach was shown to be suitable for the combinatorial synthesis of a small library of C-glycopeptides.

  authorities have imposed restrictions to minimize or even stop its use. It has therefore become imperative to identify environmentally benign solvents to replace it. Here we report on a bio derived solvent, γ-valerolactone, for the incorporation of the first amino acid onto p-alkoxybenzyl alcohol resin in solid-phase peptide synthesis. Satisfactory loading values (by a spectrophotometric method) were

  由于CH 2 Cl 2的危险性，监管机构已施加限制以最小化或什至停止使用它。因此，必须找到对环境无害的溶剂来替代它。在这里，我们报告了一种生物衍生的溶剂γ-戊内酯，用于在固相肽合成中将第一个氨基酸掺入对烷氧基苄醇树脂中。达到了令人满意的负载值（通过分光光度法）。此外，还检查了外消旋化和二肽形成，发现是可接受的。

  appropriate amino acid residue, were efficiently hydrolyzed in the presence of ZnCl2 at pH 7.0. The rapid hydrolysis of X-Ser is due to an autocatalysis of the hydroxy group in the serine residue, and is found to be accelerated by a metal ion, in particular by ZnCl2. Roles of the metal ion in the hydrolysis of peptides involving a serine residue, in relation to the recently reported protein cleavages, are

  在pH 7.0的ZnCl2存在下，在C末端具有丝氨酸残基的二肽X-Ser（其中X是合适的氨基酸残基）被有效地水解。X-Ser的快速水解是由于丝氨酸残基中羟基的自催化作用，并且被金属离子，特别是ZnCl2加速。与最近报道的蛋白质裂解有关，讨论了金属离子在涉及丝氨酸残基的肽水解中的作用。

  Methods are described herein for small molecule biochemical profiling of an individual subject for diagnosis of a disease or disorder, facilitating diagnosis of a disease or disorder, and/or identifying an increased risk of developing a disease or disorder in the individual subject. Aberrant levels of small molecules present in a sample from an individual subject are identified and diagnostic information relevant to the individual subject is obtained based on the identified aberrant levels. The obtained diagnostic information includes one or more of an identification of at least one biochemical pathway associated with the identified subset of the small molecules having aberrant levels, an identification at least one disease or disorder associated with the identified subset of the small molecules having aberrant levels, and an identification of at least one recommended follow up test associated with the identified subset of the small molecules having aberrant levels.

  小肽因其独特的特性和多样化的生物学功能而受到越来越多的关注。然而，由于其丰度低且存在多种结构异构体，实现快速分离和准确定量仍然是一个挑战。在这项研究中，我们开发了一种使用同位素化学标记超灵敏测定生物样品中二肽/三肽的新方法。我们成功合成了一种新型衍生化试剂4-(2-(乙氧基亚甲基)-3-氧代丁酰胺基)-三甲基苯胺碘化物(EOTMBA)及其氘标记同位素试剂(-EOTMBA)。总共97个小肽，包括89个二肽和8个三肽，在60℃下1.5小时内可以在​​甲醇中完全衍生化。 EOTMBA 标记后，通过 LC-MS/MS 分析在 22 分钟内完成对这些二肽/三肽的分析。该方法的准确度为 86.3%–113%，定量限范围为 0.25 fmol/L 至 5 nmol/L。利用该方法，我们对取自健康个体和胆道疾病患者的 147 份血浆、49 份尿液和 46 份胆汁样本中的二肽/三肽进行了超灵敏和准确的定量。
