    摘要:
    对 1,1-二氟环辛烷和 1,1,4,4-四氟环辛烷的 ^(19)F 核磁共振谱的温度依赖性的研究表明,这些物质在低温下更倾向于假设船椅构象。在更高的温度下,船椅系列构象内的假旋转变得迅速,并且在更高的温度下,导致环反转的平衡在 nmr 时间尺度上变得迅速。1,1,2,2-四氟环辛烷在低温下似乎更喜欢扭曲船 (S_4) 构象,并且在较高温度下,通过船船构象的假旋转变得迅速。在更高的温度下,环反转在 nmr 时间尺度上变得很快。在低温下,全氟环辛烷似乎更喜欢 (i) 扭船或 (ii) 船-船构象。如果我,那么即使在 - 173o,通过船-船构象的假旋转也必须很快。在室温下,相当于全氟环辛烷的环反转是快速的,显然是通过与舟系列之外的构象平衡的方式。已经获得了这些伪旋转和反转过程中的几个的激活参数。

    The present inventors have found that when screening for cyclic peptide compounds that can specifically bind to a target molecule, the use of a library including cyclic peptide compounds having a long side chain in the cyclic portion can improve the hit rate for cyclic peptide compounds that can specifically bind to the target molecule. Meanwhile, the present inventors have found that tryptophan and tyrosine residues, which have conventionally been used in oral low molecular-weight pharmaceuticals and are amino acid residues having an indole skeleton or a hydroxyphenyl group, are not suitable for peptides intended to attain high membrane permeability.
