The compounds represented by the formula (I), and pharmacologically acceptable salts and solvates thereof are disclosed. The compound is hydrolyzed in organisms into a compound represented by the formula in which W represents a hydrogen atom, and D represents the group -V-(CH2)p-COOR, wherein R represents a hydrogen atom. The compound inhibits the aggregation of platelets via the inhibition of the linkage of the platelet membrane protein GPIIb/IIIa to fibrinogen.
wherein A represents CH2 or CO, B represents the group -(CH2)k- or -(CH2)m-CO-, X and Y are different from each other and represent N or CH, W represents an ester moiety which can be removed under the physiological condition, and Z represents the groups (II) or (III):
wherein D represents the group -V-(CH2)p-COOR.
