  Design, synthesis and biological evaluation of novel L-isoserine tripeptide derivatives as aminopeptidase N inhibitors

  摘要：

  Aminopeptidase N (APN/CD13) is one of the essential proteins for tumour invasion, angiogenesis and metastasis as it is over-expressed on the surface of different tumour cells. Based on our previous work that L-isoserine dipeptide derivatives were potent APN inhibitors, we designed and synthesized L-isoserine tripeptide derivatives as APN inhibitors. Among these compounds, one compound 16l (IC50 = 2.51 +/- 0.2 +/- mu M) showed similar inhibitory effect compared with control compound Bestatin (IC50 = 6.25 +/- 0.4 mu M) and it could be used as novel lead compound for the APN inhibitors development as anticancer agents in the future.

  β-turn-like conformation, known as open turn identified by the absence of any intramolecular hydrogen bond, which further self-assembled to form a herringbone helix-like architecture through non-covalent interactions. To the best of our knowledge, this is the first report on a designed open turn tripeptide without a kink-forming element. However, in spite of the presence of a non-standard amino acid 2 adopted

  研究了N和C保护的三肽Boc-Gly-Phe-Phe-OMe（1）及其类似物Boc-Gly-Phg-Phe-OMe（2，Phg =苯基甘氨酸）的自组装。一个氨基酸的侧链中仅存在一个额外的亚甲基（–CH 2 –）基团，会导致其分子排列和超分子结构发生重大变化。单晶X射线衍射分析表明1采用II型β-转角样构象，称为开环转角，其通过不存在任何分子内氢键来鉴定，并通过非共价相互作用进一步自组装形成人字形螺旋状结构。据我们所知，这是有关无扭结形成元件的设计开放式转弯三肽的首份报告。然而，尽管存在非标准氨基酸2β-折叠构象采用了β-折叠构象，该构象通过结晶形式的非共价相互作用进一步自组织形成螺旋结构。还通过溶剂依赖性NMR滴定，2D NOESY和CD光谱实验研究了这些肽在溶液中的构象。在光学显微镜和场发射扫描电子显微镜（FESEM）的作用下，这些肽在乙腈-水介质中表现出两种不同的花状结构。

  Highly substituted chiral hydantoins were readily synthesized from simple dipeptides in a single step under mild conditions. This reaction proceeded through the dual activation of an amide and a tert-butyloxycarbonyl (Boc) protecting group by Tf2O-pyridine. This method was successfully applied in the preparation of a variety of biologically active compounds, including drug analogs and natural products

  (13)C NMR, alone or in combination with (1)H NMR, allows the assignment of the absolute configuration of chiral alcohols, amines, carboxylic acids, thiols, cyanohydrins, sec,sec-diols and sec,sec-aminoalcohols, derivatized with appropriate chiral auxiliaries. This extends the assignment possibilities of NMR to fully deuterated and to nonproton containing compounds.
