摘要:
Fibrinogen receptor antagonists having the structure X--Y--Z--A--B and pharmaceutically acceptable salts, wherein X is a 5, 6 or 7 membered aromatic or nonaromatic ring, and Y is a 5 or 6 membered aromatic ring, e.g., ##STR1##
摘要:
A series of non-peptide derivatives that are antagonists of the fibrinogen IIb/IIIa receptor and thus are platelet anti-aggregation compounds useful in the prevention and treatment of diseases caused by thrombus formation.
摘要:
Fibrinogen receptor antagonists of the formula: ##STR1## wherein A,B,D,E,Y are as defined in the specification, are disclosed for use in inhibiting the binding of fibrinogen to blood platelets and for inhibiting the aggregation of blood platelets.
摘要:

摘要:
Novel fibrinogen receptor antagonists of the formula: X--Y--Z-Aryl-A--B and the pharmaceutically acceptable salts thereof, wherein Aryl is a 5-membered aromatic ring system containing 1 or 2 heteroatoms chosen from N, O or S wherein ring atoms may be unsubstituted or substituted with R.sup.5 and wherein S may be substituted with 0, 1 or 2 oxygen atoms; and X comprises various Nitrogen substituents including aromatic or nonaromatic systems; Y comprises, for example, alkyl or alkylaminocarbonylalkyl groups and Z and A are substituents which when present are independently chosen from alkyl or alkyloxyalkyl or other groups as defined herein; B is (a) or (b). The claimed compounds exhibit fibrinogen receptor antagonist activity, inhibit platelet aggregation and are therefore useful in modulating or preventing thrombus formation.
