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。
