  Conformationally restricted arginine analogs

  摘要：

  We report the practical synthesis and structural characterization of a set of conformationally constrained protected arginine analogues. These enantiomerically pure analogues have the general structure 1 and are prepared in seven to eight steps from the commercially available isomers of 4-hydroxyproline. These analogues vary in side chain length and in relative and absolute stereochemistry and are suitable for the direct introduction into peptides. The resulting peptide analogues should be useful as enzymatically stable replacements for bioactive peptides and as probes for understanding the conformational aspects of protein-peptide interactions.

  A chimeric amino acid analogue is provided suitable for incorporating into peptides which compound is represented by Formula 1: ##STR1## where P.sub.1 is preferably an amine protecting agent, and P.sub.2 and P.sub.3 are preferably amine or guanidine protecting agents. X can be OH, halide, or preferably an activating group suitable for conjugating the compound of Formula 1 to a peptide by conventional means, and m and n are 0-1 and 0-2 respectively. Peptides containing the chimeric amino acid analog are provided and include a platelet-aggregation inhibitor represented by Aaa.sub.1 -CPdl-Gly-Asp-Aaa.sub.2 where Aaa.sub.1 is Gly or H, Cpdl is the compound of Formula 1 which has been deprotected and Aaa.sub.2 is a hydrophobic amino acid preferably Val.

  提供了一种适合用于合成肽中的嵌合氨基酸类似物，该化合物由以下式表示：##STR1## 其中P.sub.1 最好是氨基保护剂，P.sub.2 和P.sub.3 最好是氨基或胍啉保护剂。X 可以是OH、卤素，或者最好是适合通过常规手段与Formula 1化合物结合的活化基团，m 和n 分别为0-1和0-2。提供了含有嵌合氨基酸类似物的肽，并包括一个由Aaa.sub.1 -CPdl-Gly-Asp-Aaa.sub.2 表示的血小板聚集抑制剂，其中Aaa.sub.1 是Gly或H，Cpdl 是已去保护的Formula 1化合物，Aaa.sub.2 是一个疏水性氨基酸，最好是Val。
