Abstract: Compounds of general formula (I), which are inhibitors of the adhesion and migration of leukocytes and/or antagonists of the adhesion receptor VLA-4, the pharmaceutical preparation containing thereof and their use. Compounds of general formula (I) are useful for the preparation of medicaments intended for the treatment or prophylaxis of diseases which are caused by an undesired extent of leukocyte adhesion and/or leukocyte migration or in which cell-cell or cell-matrix interactions which are based on interactions of VLA-4 receptors with their ligands, for example of inflammatory processes, rheumatoid arthritis or allergic disorders.

Abstract: The present invention relates to compounds of the formula I (see formula I) which are inhibitors of the adhesion and migration of leucocytes and/or antagonists of the adhesion receptor VLA-4 which belongs to the group of integrins. The invention also relates to processes for their preparation, to the use of compounds of the formula I for the treatment or prophylaxis of diseases which are caused by an undesired extent of leucocyte adhesion and/or leucocyte migration or which are associated therewith or in which cell-cell or cell-matrix interactions which are based on interactions of VLA-4 receptors with their ligands play a part, for example of inflammatory processes, of rheumatoid arthritis or of allergic disorders, and also to the use of compounds of the formula I for the production of pharmaceuticals for use in such diseases, and to pharmaceutical preparations which contain the compounds of the formula I.
