BICYCLIC FIBRINOGEN ANTAGONISTS

摘要

This invention relates to compounds of formula (I), wherein A<1> to A<5> form an accessible substituted seven-membered ring, which may be saturated or unsaturated, optionally containing up to two heteroatoms chosen from the group of O, S and N wherein S and N may be optionally oxidized; D<1> to D<4> form an accessible substituted six membered ring, optionally containing up to two nitrogen atoms; R is at least one substituent chosen from the group of R<7>, or Q-C1-4alkyl, Q-C2-4alkenyl, Q-C2-4alkynyl, preferably substituted by an acidic function; R* is H, Q-C1-6alkyl, Q-C1-6oxoalkyl, Q-C2-6alkenyl or Q-C2-4alkynyl, C3-6cycloalkyl, Ar or Het, optionally substituted by one or more substituents; and R<6> is preferably a substituent containing a basic nitrogen moiety; or a pharmaceutically acceptable salt thereof, which are effective for inhibiting platelet aggregation, pharmaceutical compositions for effecting such activity, and a method for inhibiting platelet aggregation.
