  The present invention relates to compounds of the formula I, wherein R1; R2; Z; A; B; D; Q; J; V; G and M have the meanings indicated in the claims. The compounds of the formula I are valuable pharmacologically active compounds. They exhibit a strong anti-aggregating effect on platelets and thus an anti-thrombotic effect and are suitable, e.g., for the therapy and prophylaxis of cardio-vascular disorders like thromboembolic diseases or restenoses. They are reversible antagonists of the platelet ADP receptor P2Y12, and can in general be applied in conditions in which an undesired activation of the platelet ADP receptor P2Y12 is present or for the cure or prevention of which an inhibition of the platelet ADP receptor P2Y12 is intended. The invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as active ingredients in pharmaceuticals, and pharmaceutical preparations comprising them.

• Identification of High-Affinity P2Y₁₂ Antagonists Based on a Phenylpyrazole Glutamic Acid Piperazine Backbone

  A series of novel, highly potent P2Y(12) antagonists as inhibitors of platelet aggregation based on a phenylpyrazole glutamic acid piperazine backbone is described. Exploration of the structural requirements of the substituents by probing the structure-activity relationship along this backbone led to the discovery of the N-acetyl-(S)-proline cyclobutyl amide moiety as a highly privileged motif. Combining the most favorable substituents led to remarkably potent P2Y(12) antagonists displaying not only low nanomolar binding affinity to the P2Y(12) receptor but also a low nanomolar inhibition of platelet aggregation in the human platelet rich plasma assay with IC50 values below 50 nM. Using a homology and a three-dimensional quantitative structure-activity relationship model, a binding hypothesis elucidating the impact of several structural features was developed.
