Substituted 1-phenyl-oxazolidin-2-one derivatives, their preparation and their use as adhesion-receptor antagonists.

摘要

Novel oxazolidinone derivatives of the formula I wherein R<1> is a phenyl radical which is unsubstituted or substituted once by CN, H2N-CH2-, A2N-CH2-, H2N-C(=NH)-, H2N-C(=NH)-NH-, H2N-C(=NH)-NH-CH2-, HO-NH-C(=NH)- or HO-NH-C(=NH)-NH-, X is O, S, SO, SO2, -NH- or -NA-, B is A is alkyl having 1 to 6 C atoms, R<2> is H, A, Li, Na, K, NH4 or benzyl, R<3> is H or (CH2)n-COOR<2>, E in each case independently of one another is CH or N, Q is O, S or NH, m is 1, 2 or 3 and n is 0, 1, 2 or 3, and their physiologically acceptable salts inhibit the binding of fibrinogen to the corresponding receptor and can be used for the treatment of thromboses, apoplexy, cardiac infarct, inflammations, arteriosclerosis, osteoporosis and tumours.
