  • Synthesis of libraries of thiazole, oxazole and imidazole-based cyclic peptides from azole-based amino acids. A new synthetic approach to bistratamides and didmolamides

    Treatment of a 1 : 1 mixture of the thiazole-based amino acids 8a and 8b with FDPP–i-Pr2NEt in CH3CN gave a mixture of the cyclic trimers 14, 15, 16 and 17 and the cyclic tetramers 19 and 23 in the ratio 2 : 7 : 5 : 8 : 1 : 1 and in a combined yield of 70%. Separate coupling reactions between the bisimidazole amino acid 45 and the thiazole/oxazole amino acids 43a and 42a in the presence of FDPP–i-Pr2NEt led to the bisimidazole based cyclic trimers 55 and 57 respectively (54–57%) and to the cyclic tetramer 56 (8–11%). Similar coupling reactions involving the bisthiazole and bisoxazole amino acids 49 and 47 with the imidazole/oxazole/thiazole amino acids 41a, 42a and 43a gave rise to the library of oxazole, thiazole and imidazole-based cyclic peptides 58, 59, 60, 61, 62, 63, 64 and 65. A coupling reaction between the bisthiazole amino acid 49 and the oxazole amino acid 73 led to an efficient (36% overall) synthesis of bistratamide H (67) found in the ascidian Lissoclinum bistratum. Coupling reactions involving oxazolines with thiazole amino acids were less successful. Thus, a coupling reaction between the phenylalanine-based oxazoline amino acid 71a and either the thiazole amino acid 8a or the bisthiazole amino acid 74 gave only a 2% yield of the cyclic hexapeptide didmolamide A (4) found in the ascidian Didemnum molle. Didmolamide B (68) was obtained in 9% yield from a coupling reaction between 74 and the phenylalanine threonine amino acid 72, using either FDPP or DPPA.
    噻唑氨基酸8a和8b的1:1混合物与FDPP-i-Pr2NEt在CH3CN中处理,得到了环状三聚体14、15、16和17以及环状四聚体19和23的混合物,其比例为2:7:5:8:1:1,总产率为70%。在FDPP-i-Pr2NEt存在下,双咪唑氨基酸45与噻唑/噁唑氨基酸43a和42a分别进行的单独偶联反应,分别得到了双咪唑基环状三聚体55和57(产率54-57%)以及环状四聚体56(产率8-11%)。类似地,双噻唑和双噁唑氨基酸49和47与咪唑/噁唑/噻唑氨基酸41a、42a和43a进行的偶联反应,生成了噁唑噻唑咪唑基环状肽库58、59、60、61、62、63、64和65。双噻唑氨基酸49与噁唑氨基酸73之间的偶联反应,高效(总产率36%)合成了在海鞘Lissoclinum bistratum中发现的双层板H(67)。含有噻唑氨基酸噁唑啉的偶联反应效果较差。因此,苯丙酸基噁唑氨基酸71a与噻唑氨基酸8a或双噻唑氨基酸74之间的偶联反应,仅得到了在海鞘Didemnum molle中发现的环状六肽didmolamide A(4),产率仅为2%。使用FDPPDPPA,从74与苯丙酸苏氨基酸72的偶联反应中获得了产率为9%的didmolamide B(68)。

  • Synthesis of a new class of imidazole-based cyclic peptides
    作者:Gebhard Haberhauer、Frank Rominger
    DOI:10.1016/s0040-4039(02)01365-5
    日期:2002.9
    A new class of cyclic peptides based on dipeptidyl imidazoles is presented. Their structure consists of imidazole units alternating with standard amino acid residues and resembles naturally occurring marine cyclopeptides such as westiellamide and ascidiacyclamide.
    提出了一类新的基于二肽基咪唑的环肽。它们的结构由与标准氨基酸残基交替排列的咪唑单元组成,类似于天然存在的海洋环肽,例如韦氏酰胺和Ascidiacyclamide。
  • Imidazole-Peptide Foldamers: Parabolic Dependence of the Folding Process on the Water Content of the Solvent

    of the solvent in a parabolic way. In a pure organic medium, the helix is stabilized by hydrogen bonds between the hydrogen atoms of the amide groups and the nitrogen atoms of the azole ring. In aqueous solution, the formation of the helix is driven by dispersion interactions. The formation of the helix is more pronounced in aqueous solution than in organic solvents.
    唑肽的寡聚体已经从多种海洋生物中分离出来。到目前为止,这些含唑的二肽类似物低聚物仅被发现为环状n单体(主要是三聚体和四聚体)。本文中,我们显示了含咪唑的假肽在不同溶剂中形成螺旋状二级结构。可以通过将单个手性咪唑单元连接至低聚物的N末端来确定螺旋的螺旋感。通过圆二色性(CD)光谱的研究表明,螺旋的折叠过程以抛物线方式取决于溶剂的含量。在纯有机介质中,螺旋结构通过酰胺基团的氢原子和唑环的氮原子之间的氢键稳定。在溶液中,螺旋的形成是由分散相互作用驱动的。螺旋的形成在溶液中比在有机溶剂中更明显。
