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.
