摘要

A peptide compound represented by general formula (I) or a pharmacologically acceptable salt thereof. In said formula, R<1> represents aryl which may have one or more suitable substituents; R<2> represents optionally protected carboxy(lower)alkyl; R<3> represents a carboxamide group; A<1> represents lower alkylene; A<2> represents -N(R<4>)-CH2CO- or -NH-(R<4>)HCO- (wherein R<4> represents lower alkyl); A<3> represents lower alkylene which may have one or more substituents; m and n may be the same or different from each other and each represents 0 or 1, both being usable as a glycoprotein IIb/IIIa antagonist, a platelet aggregation inhibitor, and so on.
