  Structure-Based Design, Synthesis, and Biological Evaluation of Irreversible Human Rhinovirus 3C Protease Inhibitors. 2. Peptide Structure−Activity Studies

  摘要：

  The structure-based design, chemical synthesis, and biological evaluation of various peptide-derived human rhinovirus (HRV) 3C protease (3CP) inhibitors are described. These compounds are comprised of an ethyl propenoate Michael acceptor moiety and a tripeptidyl binding determinant. The systematic modification of each amino acid residue present in the binding determinant as well as the N-terminal functionality is described. Such modifications are shown to provide irreversible HRV-14 3CP inhibitors with anti-3CP activities (k(obs)/[I]) ranging from 60 to 280 000 M-1 s(-1) and antiviral EC50's which approach 0.15 mu M. An optimized inhibitor which incorporates several improvements identified by the structure-activity studies is also described. This molecule displays very rapid irreversible inhibition of HRV-14 3CP (k(obs)/[I] = 800 000 M-1 s(-1)) and potent antiviral activity against HRV-14 in cell culture (EC50 = 0.056 mu M). A 1.9 Angstrom crystal structure of an S-alkylthiocarbamate-containing inhibitor complexed with HRV-8 3CP is also detailed.

  模拟p53-MDM2 / MDMX蛋白-蛋白质相互作用的α-螺旋模拟磺基-γ-AA肽抑制剂。

  摘要：

  拟肽支架的使用是抑制蛋白相互作用的一种有前途的策略。在本文中，我们证明了可以合理设计磺基-γ-AA肽以模仿p53α-螺旋并抑制p53-MDM2 PPI。最好的抑制剂对MDM2的Kd和IC50值分别为26 nM和0.891μM，是破坏p53-MDM2 / MDMX相互作用的最有效的非天然拟肽抑制剂之一。使用荧光偏振分析，圆二色性，核磁共振波谱和计算模拟，我们证明了磺基-γ-AA肽采用类似于p53的螺旋结构，并通过结合到MDM2的疏水缝隙竞争性抑制p53-MDM2相互作用。有趣的是 通过增强p53转录活性并诱导MDM2和p21的表达，吻合的磺酰基-γ-AA肽显示出有希望的细胞活性。此外，磺基-γ-AA肽对蛋白水解表现出显着的抗性，从而增强了它们的生物学潜力。我们的结果表明，磺基-γ-AA肽是一类新型的破坏PPI的非天然螺旋折叠剂。

  Peptide vinyl sulfones were prepared from 2-chlorotrityl resin-bound phenolic amino vinyl sulfones in high yield and purity. This method enables the convenient synthesis of peptide vinyl sulfones having different amino acids at the P(1) position. It also allows efficient synthesis of vinyl sulfone-containing, activity-based probes of cysteine proteases used in a proteomic experiment.

  The reductive alkylation of primary amines with aldehydes or ketones is an important tool in the synthesis of wide variety of amines. We described here a novel, one-pot reductive alkylation method using multifunctional S-ethyl thioesters as a source for in situ generation of aldehydes to alkylate a range of multifunctional primary amines. The corresponding multifunctional secondary amines were obtained

  伯胺与醛或酮的还原性烷基化反应是合成多种胺的重要工具。我们在这里描述了一种新颖的一锅还原烷基化方法，该方法使用多功能S-乙基硫酯作为原位生成醛以烷基化一系列多功能伯胺的来源。以良好至优异的产率（大部分＞ 90％）获得相应的多官能仲胺。该一锅还原烷基化包括在低于20摄氏度的温度下用三乙基硅烷处理受保护的S-乙基硫酯，伯胺，10％Pd / C和三乙酰氧基硼氢化钠在N，N-二甲基甲酰胺中的混合物30分钟。当醛不够稳定以至于不能分离时，该方法具有特殊的优点，因此不适合逐步还原烷基化的策略。1（S）-[（（9-芴基甲氧基羰基）氨基] -4-氧代丁酸叔丁基酯（10）就是这种情况，它不能从α-叔丁基γ-S-乙基（S）-N获得-（9-芴基甲氧基羰基）硫代谷氨酸盐（9）。但是，通过我们的一锅还原烷基化方法，用9处理9-芴甲基苯丙氨酸酯（6a）得到了叔丁基2（S）-[（9-芴基甲氧基羰基）氨基] -4-[[3-苯基-1（

  A new class of peptide mimics termed “γ-AApeptides” has been described. The design and synthesis of γ-AApeptides, and potential bioactivities towards p53/MDM2 interaction were demonstrated. γ-AApeptides were also found to be highly resistant to proteolysis. The development of sequence-specific γ-AApeptides may lead to a family of peptidomimetics with a new framework for drug discovery or peptide/protein mimicry.

  The mimicry of protein tertiary structure by oligomers with unnatural backbones is a significant contemporary research challenge. Among common elements of secondary structure found in natural proteins, sheets have proven the most difficult to address. Here, we report the systematic comparison of different strategies for peptide backbone modification in β-sheets with the goal of identifying the best method for replacing a multi-stranded sheet in a protein tertiary fold. The most effective sheet modifications examined led to native-like tertiary folding behavior with a thermodynamic folded stability comparable to the prototype protein on which the modified backbones are based.
