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.

they are characterized by poororalbioavailability and a need for boosting with a pharmacokinetic enhancer, which results in additional drug–drug interactions that are sometimes difficult to manage. We investigated a chemo-activated, acyl migration-based prodrug design approach to improve the pharmacokinetic profile of 1 but failed to obtain improved oralbioavailability over dosing the parent drug
