N-Aroyl- alpha -aminocarboxylic acid derivatives of the formula in which L, R' to R''' and Q have the meaning given in the description, can be used for the treatment or prophylaxis of diseases which are caused by the binding of adhesive proteins to blood platelets, as well as by blood platelet aggregation and cell-cell adhesion. They are prepared by removing protective groups in appropriately protected compounds or by conversion of the cyano group to the amidino group in appropriate nitriles.
