  α-氨基氧基寡肽：一类新型抗癌折叠剂的合成，二级结构和细胞毒性

  摘要：

  α-氨基氧基肽是具有高蛋白水解和构象稳定性的拟肽折叠剂。为了获得对α-氨基氧基寡肽的更好合成途径，我们使用了溶液和固相支持方法的直接组合，并获得了对一组癌细胞显示出显着抗癌活性的寡聚体。我们解决了绕螺旋轴多圈旋转的α-氨氧基肽的第一个X射线晶体结构。晶体结构显示出右旋2 8螺旋构型，每转正好有两个残基，螺旋间距为5.8Å。通过二维ROESY实验，分子动力学模拟和CD光谱，我们能够确定2 8螺旋是有机溶剂中的主要构象。在水溶液中，α-氨氧基肽在酸性pH下以2 8螺旋构象存在，但随着pH的增加，其二级结构表现出显着变化。在模型膜存在下，最具细胞毒性的α-氨基肽具有增加的吸收2 8螺旋构象的倾向。这表明在作用模式研究中观察到的2 8螺旋构象与膜分解活性之间存在相关性，从而为α-氨氧基肽的折叠特性和生物活性提供了新的见解。

  Synthesis and Characterization of Chiral N−O Turns Induced by α-Aminoxy Acids

  摘要：

  Chiral alpha -aminoxy acids of various side chains were synthesized with high optical purity starting from chiral alpha -amino acids. The conformations of diamides 13a-e, 15, and 16 were probed by using NMR, FT-IR, and CD spectroscopic methods as well as X-ray crystallography. The right-handed turns with eight-membered-ring intramolecular hydrogen bonds between adjacent residues (called the N-O turns) were found to be preferred for D-aminoxy acid residues, and they were independent of the side chains. The rigid chiral N-O turns should have great potential in molecular design.

• Structure–activity relationships of novel endomorphin-2 analogues with N–O turns induced by α-aminoxy acids

  Endomorphin-2 (H-Tyr-Pro-Phe-Phe-NH2, EM-2) is a putative endogenous mu-opioid receptor ligand. To study the structure-activity relationship against its receptor, we introduced N-O turns into EM-2 and got the analogues with potent affinities for p-opioid receptor. Our results indicated that N-O turn structures at the PrO2-aminoxy-Phe(3) position of EM-2 analogues played important roles for their affinities. These novel analogues with N-O turns provided a new approach to develop potent analgesics related to EM-2. (c) 2005 Elsevier Ltd. All rights reserved.
