  Structure-based design of dipeptide derivatives for the human neutral endopeptidase

  摘要：

  Neutral endopeptidase (NEP) plays a key role in the metabolic inactivation of various bioactive peptides such as atrial natriuretic peptide (ANP), endothelins, and enkephalins. Furthermore, NEP is known to work as elastase in skin fibroblast. Therefore, effective inhibitors of NEP offer significant therapeutic interest as antihypertensives, analgesics, and skin anti-aging agents. Recently, the X-ray crystal structure of human NEP complexed with phosphoramidon has been reported and provided insights into the active site specificity of NEP. Here, we designed new inhibitors by using in silico molecular modeling and synthesized them by short steps. Expectedly, we found highly effective inhibitors with sub-nanomolar levels of IC(50) values. These results indicate that our structure-based molecular designing program is useful for obtaining novel NEP inhibitors. Furthermore, these inhibitors may be attractive leads for the generation of new pharmaceuticals for NEP-related diseases. (C) 2011 Elsevier Ltd. All rights reserved.

  开发杂三芳基化合物作为亚型选择性和有效抑制 Sirt5 的新化学型

  摘要：

  与其他去乙酰化酶（NAD +依赖性 III 类赖氨酸脱酰基酶）相比，Sirt5 的抑制作用尚未得到很好的研究。我们目前的工作基于最近发现的 Sirt5 抑制剂巴柳氮，这是一种经批准的药物，口服后生物利用度可忽略不计。在之前的工作中首次了解其构效关系后，我们现在能够开发出杂芳基-三芳基化合物作为一种新型化学类型的药物样、强效和亚型选择性 Sirt5 抑制剂。铅结构的不利偶氮基团以系统和全面的方式进行了修饰，使我们得到了一些开链，最重要的是，五元杂环取代物（异恶唑CG_209、三唑CG_220、吡唑CG_232) 具有非常令人鼓舞的体外活性（Sirt5 上的 IC 50在低微摩尔范围内，<10 μM）。这些先进的抑制剂没有细胞毒性，并显示出良好的药代动力学特性，这通过活细胞成像实验对线粒体的渗透性得到了证实。此外，与作为参考化合物的巴柳氮相比，计算类似物的相对游离结合亲和力的结果与体外获得的抑

  Application of substituted 2-(trimethylsilyl)ethyl esters to suppress diketopiperazine formation

  摘要：

  The use of differently substituted 2-(trimethylsilyl)ethyl esters for C-terminal protection in peptide synthesis has been investigated. While the use of the unsubstituted 2-(trimethylsilyl)ethyl ester resulted in a substantial amount of diketopiperazine at the dipeptide stage, use of the corresponding methyl-substituted silyl ester gave a significant reduction of this undesired pathway. Both esters could be deprotected by fluoride-induced cleavage under mild conditions. (C) 2004 Elsevier Ltd. All rights reserved.

  A laminin-related antimetastatic peptide was conjugated with chitosan, and antimetastatic activity of the peptide–chitosan conjugate was assayed. Chitosan was converted to its organosoluble derivative, 6-O-trityl-chitosan, in 3 steps, and then coupled with the peptide portion, Ac-Tyr-Ile-Gly-Ser-Arg-βAla-OH (βAla; β-alanine), which contains a spacer amino acid at the carboxy-terminus. The product was treated with CHCl2CO2H to afford the desired conjugate, Ac-Tyr-Ile-Gly-Ser-Arg-βAla–chitosan. The peptide was introduced to every 6.3 glucosamine residues. The conjugate proved to have higher inhibitory activity against experimental lung metastasis of B16BL6 melanoma cells in mice than did the parent peptide.
