The design, synthesis and conformational studies of a new β-hairpin mimic, 2, are described in this paper. The design towards hairpin 2 is based on the assembly of the bifunctional DKP-1 as a β-turn inducer, a peptidomimetic strand, namely 5-amino-2-methoxybenzhydrazide, to stabilize the formation of β-sheets, and finally a tetrapeptide sequence, GVVI, containing the hydrophobic residues Val, Ile and
本文介绍了一种新型β-发夹模拟物2的设计,合成和构象研究。发夹2的设计基于组装成β-转角诱导剂的双功能DKP - 1,拟肽链(即5-氨基-2-甲氧基苯甲酰肼),以稳定β-折叠的形成,最后是四肽序列。 ,GVVI,含有疏水残基Val,Ile和Gly。发夹2的合成在溶液中进行,而质子溶剂中β-发夹的形成已通过NMR研究证实(1 H和13C化学位移,邻近偶合常数和ROE),并通过计算研究(Monte-Carlo构象搜索,分子动力学和DFT计算)得到证实。
